“You’ve probably noticed signs posted at pharmacies and grocery stores let you know you can get a flu shot now.  But should you?

QUESTION: Is there a time that’s best to get the vaccine? ANSWER: Yes, during the month of October. SOURCES: Three practicing physicians: Dr.Stuart Ray, LaTasha Perkins and Linda Fu. The Centers for Disease Control and Preventionm and the Immunization Action Coalition or I-A-C, an educational non-profit that works with the CDC.

Dr. Stuart Ray, an infectious disease specialist at Johns Hopkins, says October is your best bet to get the flu shot. According to Ray, that’s when flu season really starts to pick up. “The most important thing is to get it when it’s available. Certainly, the best time is probably before the end of October”. Our other experts agree, like family medicine doctor LaTasha Perkins and pediatrician doctor Linda Fu. “October is going to be the optimum month to get it,” Perkins agreed.

Pros and Cons of Shields for Protection from COVID-19

Are face shields more effective protection against the coronavirus than face masks? AARP asked the experts to explain the pros and cons of each.

Read full story of excerpts below at Source: >Pros and Cons of Shields for Protection from COVID-19

“One of the benefits of face shields is that they protect the entire face, including the eyes, which along with the nose and mouth can be a gateway for the coronavirus and other germs to enter the body. The plastic panel that hangs from the top of the forehead and extends below the chin prevents large respiratory droplets that are thought to carry the virus from reaching these areas of potential infection. Face shields also reduce the likelihood that you’ll introduce virus-packed particles on your own …They keep you from touching “your hands to your eyes and nose and mouth. If you’re wearing one, it’s pretty hard to do that” 

“A recent JAMA report found that when community health workers added face shields to other protective equipment (face masks and gloves), COVID-19 infection rates among the workers dropped to zero. Similar findings have been published in The Lancet: Researchers looked at studies evaluating the effectiveness of nonpharmacologic interventions and found that eye protection was associated with a lower risk of virus infection. “Eye protection is typically underconsidered and can be effective in community settings,” the report’s authors write.

It’s double protection,” Perencevich says about layering a face shield over a cloth face covering. “The face shield will protect the mask from being contaminated and then block additional droplets from your whole face, including your eyes.”

VIDEO: How To Protect Yourself From Coronavirus That Can Linger In The Air : Goats and Soda : NPR

Scientists say it’s increasingly clear that airborne virus particles help the coronavirus superspread. Here’s what they recommend to reduce the risks.

Full story of excerpts below at Source: >VIDEO: How To Protect Yourself From Coronavirus That Can Linger In The Air : Goats and Soda : NPR

In some settings — especially poorly ventilated indoor rooms where many people are gathering — researchers increasingly believe that clouds of the virus expelled when someone speaks are able to stay aloft in the air and potentially infect people farther away than the recommended 6 feet of social distance.

In these settings, an infectious person shouting or laughing or coughing can release clouds containing the virus that can build up, linger and waft in the air — and then be inhaled by passersby and settle in their lungs.

You limit aerosol transmission by increasing ventilation and increasing air circulation,” says Seema Lakdawala, a flu researcher at University of Pittsburgh, which means opening the windows that surround you and putting fans in them, facing inward, to draw outside air in. That fresh air will scatter any clouds of virus that might exist. That way, you’re less likely to breathe in a big infectious dose.

When you can, move your get-together outside to a location where fresh air is all around you — a backyard, for example. Lakdawala’s neighborhood hosts happy hours, “where everybody brings a lawn chair and we sit on someone’s lawn. Everyone is spatially distanced and brings their own drink.”

Much of this is common knowledge by now, but make sure you wear your mask correctly — making sure that it fits snugly over your nose and mouth while not obstructing your ability to breathe — and that you keep a personal space bubble of at least 6 feet between you and other people.

The mask will catch a lot of the droplets that come out when you speak or laugh or cough — and also block some of other people’s droplets from getting into your nose and mouth.

Superspreading Is A Hallmark Of The Coronavirus : Goats and Soda : NPR

>Superspreader News Last 20 days

That’s the word that one disease researcher uses to describe COVID-19. And now scientists are discovering the reasons that this virus is readily transmitted at “superspreader events.”

Full story of excerpts below at Source: >Superspreading Is A Hallmark Of The Coronavirus : Goats and Soda : NPR

“A person with a high viral load walks into a bar. That, according to researchers who study the novel coronavirus, is a recipe for a superspreading event — where one person or gathering leads to an unusually high number of new infections.

“And that kind of occurrence is increasingly considered a hallmark of the coronavirus that causes COVID-19. “There are some really good estimates out there that suggest that between 10% and 20% of cases are responsible for about 80% of transmission events.

“And two of the main reasons, say researchers, are the way this coronavirus spreads and the behavior of infected individuals. A key feature that helps this virus superspread is its ability to transmit through the air in closed indoor settings,

“It appears to spread efficiently from people who don’t yet know they’re sick. Leung says research shows that 40% of coronavirus transmission is taking place before a patient shows symptoms. And people may actually be most contagious the day or two before they start feeling sick.

Viral load actually increases a couple of days before symptoms show up...The virus is spreading from one person’s respiratory tract to another’s — even though the person who’s spreading it may feel totally fine. It may come down to differences in biology, such as how much virus a person sheds in sighs and coughs and sneezes — or even how the virus comes out from the respiratory tract. That’s “bad news,” says Leung, and means that containing the coronavirus requires more intensive interventions than past disease outbreaks like SARS.

“So when a person with a high viral load walks into a crowded bar — one with poor ventilation and where nobody is wearing masks or social distancing — that’s a superspreading cocktail.

“This pandemic has upended our world. It’s cost millions of people their jobs, closed schools, taken a lot of lives. It’s had such a huge effect in such a short period of time, so it’s understandable that many people comfort themselves by thinking this will pass; sooner or later, this virus will just go away.

13 minute podcast and Read full story of excerpts below at Source: >Why Herd Immunity Won’t Save Us : Short Wave : NPR

as good as herd immunity might look on paper, the real world is turning out to be a lot more complicated. All over the globe, millions are being infected, but the coronavirus is still here… “I think it’s going to be with us probably forever at this point. I mean, at a global scale, it’s going to be with us, and it’s how we decide to live with it… “herd immunity – what it is, why it became so popular in this pandemic and why it probably just isn’t going to happen.

“as soon as governments start floating these ideas of letting the virus pass through the population, scientists start projecting astronomical death counts that would result. And so herd immunity as an official policy basically dies before it ever gets started. There is just no way politically to embrace the strategy

“But the idea of natural herd immunity doesn’t really die. And this is what I find interesting. There’s still this sort of idea that somehow, the virus will eventually just vanish. And you’ve been hearing this a lot in recent weeks

Sweden never officially pursued a herd immunity approach, but they got kind of as close as any country has. They had this really light lockdown. They limited gatherings to 50 people or less, kept everything open with minor restrictions, like table-only seating at restaurants. And in the spring, Swedish officials were bragging that Stockholm might effectively reach herd immunity by the end of May.

Blood tests showed not that many people in Sweden have been infected with the coronavirus. It’s maybe 5%. And for natural herd immunity for this virus, that number has to reach more like 50% to 80%. Meanwhile, Sweden has had higher death rates than its Nordic neighbors like Norway, and their economy is suffering badly. So this has not worked well in practice.

Prior to Fauci’s comments, measures like temperature screenings—along with spraying disinfectant in public transportation, or walking through hand sanitizer showers—had been criticized as “safety theater,” meaning they are not proven to stem the spread of the virus.

“According to The Atlantic, temperature checks can backfire because not everyone who has the coronavirus will have fever as a symptom, so contagious people could be cleared to enter a business or other space where they could infect more people.

“Infected children have at least as much of the coronavirus in their noses and throats as infected adults, according to the research. Indeed, children younger than age 5 may host up to 100 times as much of the virus in the upper respiratory tract as adults, the authors found.” (And its hard to keep them wearing masks)

“But one takeaway from this is that we can’t assume that just because kids aren’t getting sick, or very sick, that they don’t have the virus…experts were alarmed to learn that young children may carry significant amounts of the coronavirus.

The results are consistent with those from a German study of 47 infected children between the ages 1 and 11, which showed that children who did not have symptoms had viral loads as high as adults’, or higher. And a recent study from France found that asymptomatic children had C.T. values similar to those of children with symptoms. C.T. values are a reasonable proxy for the amount of coronavirus present, said Dr. Kindrachuk, who relied on this metric during the Ebola outbreaks in West Africa.

A surgical mask was the most effective at blocking droplets and aerosols from talking, coughing and sneezing. But if you can’t get hold of one, a cloth mask is the next best thing, and the more layers the better.

We confirmed that even speaking generates substantial droplets. Coughing and sneezing (in that order) generate even more.

In practice, we don’t yet know which has a greater effect — wearing masks to prevent infected people spreading to others or protecting well people from inhaling infected aerosols. Probably both are equally important.

“…they really are protective of you as an individual. And sort of putting it all together, it really is that the less virus that you get in, the less sick you’re likely to be. So not only do masks protect you – and we’ve seen from getting the virus and altogether.

“And that’s been seen in hamster studies. That’s been seen in a health care worker study that was just published last week in JAMA. But if you do get the virus in, you get very little in. And you’re likely to get what’s called an asymptomatic infection or not have any symptoms at all and – or a very mild infection.

it really looks like any country that has adopted universal mask wearing – and many, many countries have – even as they open up and they’re seeing each other more and there’s more cases, it has led to much, much fewer deaths or severe illness. So the idea about this virus is it’s completely bizarre how it can cause no symptoms in some people and very, very severe symptoms in others…even in settings where there are outbreaks but everyone masked, there’s, like, a 95% rate of not having symptoms at all

Although they’re “particularly effective” at preventing large airborne respiratory droplets — which could result from a person nearby coughing or sneezing — they don’t do as good of a job with blocking smaller particles, as face shields don’t completely seal off the face. With smaller particles, they don’t travel like bullets, they hover in the air and below that face shield you’re still breathing in that air,” Edwards says.

Covid-19 cases by age: Why more young people are getting sick – Vox

Mixed public health messages and misunderstandings of risk haven’t helped.

Full Story at Source: >Covid-19 cases by age: Why more young people are getting sick – Vox

“Nationwide, “the average age of people getting infected is now a decade and a half younger than it was a few months ago,” Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said in a July 6 press briefing.

This seems to already be happening, with assisted living facility cases climbing in Houston and Phoenix, as well as in Florida now. “We first see it in the community, and then we see it in the residents and staff, and then you see the deaths,” David Grabowski, a health care policy expert at Harvard Medical School, told the Wall Street Journal.

“A higher percentage of young people — and a lower percentage of elderly people — getting infected could seem like a good thing. For one, it should mean fewer deaths. It also should mean less strain on the health care system and its workers. But in the states with larger outbreaks, including Arizona and Texas, hospitals are already getting overwhelmed with young and old alike.

“The social isolation of shutdowns also seems to be taking a much higher psychological toll on younger than older adults, and is potentially driving them to gather in risky indoor settings. A CDC study in May found that nearly half of all 18- to 29-year-olds surveyed had been feeling at least some symptoms of anxiety or depression — a higher proportion than for other age groups (which was closer to one-third for those 30 to 59). (The CDC now also offers specific guidance for teens and young adults who might be struggling.)

Here’s Why You Shouldn’t Go To A ‘Covid Party’ or ANY Party

“A 30 year old male died after recently attending a ‘Covid party’ in San Antonio, Texas. The motivation for holding such parties appears to be a curiosity if the virus is real, and to see if anyone gets infected.

See Full Story at Source: >Here’s Why You Shouldn’t Go To A ‘Covid Party’

“Do you still believe that SARS-CoV-2, the virus responsible for Covid-19, is a hoax? Well a 30 year old male in San Antonio, Texas who recently attended a “Covid party” believing that the virus might be a hoax is now dead. He reportedly told nurses before he died this week at Methodist Hospital in San Antonio, “I think I made a mistake. I thought this was a hoax, but it’s not.”

“Dr. Jane Appleby, the Chief Medical Officer for Methodist Hospital and Methodist Children’s Hospital, released a statement indicating that the man had attended a gathering with an infected individual to determine if the coronavirus was real. He wanted to see whether he could get infected after attending the event. Appleby shared the story as a warning to others throughout the US, where coronavirus cases are surging in a majority of states:

“The basis for holding Covid parties, so the thinking goes, is similar to the concept of holding a “chicken pox party” in order to get the disease and just “get it over with,” in order to gain immunity. But the two diseases are quite different and “getting it over with” likely holds a higher degree of uncertainty with respect to Covid-19.

“The CDC has warned that people infected with the coronavirus should not attend gatherings or parties. Simply put, any event where people do not practice social distancing and do not consistently wear face coverings represent significant risk for transmission. Such is also the case with congregating at bars— due to alcohol’s ability to reduce inhibitions, encouraging people to gather closer while speaking, spreading virus-laden droplets which may become airborne, existing as aerosols for up to 3 hours.

EPA’s previous releases approved disinfectants for “coronaviruses” but this is the first tested on the new pandemic coronavirus SARS-CoV-2 which causes Covid-19 worldwide this year.

WASHINGTON (July 6, 2020) — Throughout the COVID-19 public health emergency, the U.S. Environmental Protection Agency (EPA) has worked to provide the American public with information about how to safely and effectively kill the novel coronavirus, SARS-CoV-2, on surfaces. Last week, EPA approved two products, Lysol Disinfectant Spray (EPA Reg No. 777-99) and Lysol Disinfectant Max Cover Mist (EPA Reg No. 777-127), based on laboratory testing that shows the products are effective against SARS-CoV-2.

“This week, EPA updated the entries for two products on List N to show they have now been tested directly against SARS-CoV-2. These are the first List N products for which the agency has reviewed laboratory testing data and approved label claims against SARS-CoV-2. EPA expects to approve such claims for additional List N products in the coming weeks.

“All products on EPA’s List N meet the agency’s criteria for effectiveness against SARS-CoV-2. When using an EPA-registered disinfectant, follow the label directions for safe, effective use. Make sure to follow the contact time, which is the amount of time the surface should be visibly wet. Read the agency’s infographic on how to use these products.

“Studies by the signatories and other scientists have demonstrated beyond any reasonable doubt that viruses are released during exhalation, talking, and coughing in microdroplets small enough to remain aloft in air and pose a risk of exposure at distances beyond 1 to 2 meters (yards) from an infected individual,”

“For example, at typical indoor air velocities, a 5 nanometre droplet will travel tens of meters, much greater than the scale of a typical room, while settling from a height of 1.5 metres (about five feet) to the floor.” What’s not clearly understood is how important droplet size is to coronavirus transmission,

“A lot of people crowded close together indoors where it is poorly ventilated — that is what drives the pandemic,” … A loud bar, where people must raise their voices to be heard, is a perfect storm of close contact, poor air circulation and people generating a lot of virus-carrying particles by talking, laughing and shouting.

Advice to avoid coronavirus transmission:

“I am very much concerned about the general public and schools and ventilation in school buildings and in dorms on college campuses and in bars and in churches and where people sing and where people congregate,” 

• Provide sufficient and effective ventilation (supply clean outdoor air, minimize recirculating air) particularly in public buildings, workplace environments, schools, hospitals and age care homes.

• Supplement general ventilation with airborne infection controls such as local exhaust, high efficiency air filtration, and germicidal ultraviolet lights. (These would be placed high up in the ceiling to avoid damage to people’s eyes and skin)

• Avoid overcrowding, particularly in public transport and public buildings.

“Such measures are practical and often can be easily implemented; many are not costly, For example, simple steps such as opening both doors and windows can dramatically increase air flow rates in many buildings…In buildings, carbon dioxide monitors can help managers know if the air is being refreshed properly.

“In a car, open windows and make sure the air conditioning or heat is not recirculated but set to include outside air.

“Face masks can also offer the wearer some protection — though how much varies greatly, depending on the type of mask. No mask will offer full protection, and they should not be viewed as a replacement for physical distancing of at least 6 feet from others, frequent hand-washing and avoiding crowds. When you combine masks with those measures, they can make a big difference.

“…consider the fabric itself. The tightness of the weave is really important. … To check your fabric, hold it up to a light: If you can easily see the outline of the individual fibers, it’s not going to make a great filter. Researchers say a thick 100% cotton weave is a good bet. That’s because at the microscopic level, the natural fibers in cotton tend to have more three-dimensional structure than synthetic fibers, which are smoother…That 3D structure can create more roadblocks that can stop an incoming particle

“Think multiple layers. Several studies have found that masks made of multiple layers are more effective at blocking small particles. A good option: a mask made of two layers of a thick-weave fabric with a built-in pocket where you can place a filter...The best bet for the material to slip in as a filter is polypropylene, which is derived from plastic.. “If you go to Walmart, you look for Oly-fun, which is the brand name of that fabric. It’s also called spunbond

“polypropylene is great as a physical filter but has another benefit: It holds an electrostatic charge. In other words, it uses the power of static electricity. Think of the static cling that can happen when you rub two pieces of fabric together, …That’s basically what’s happening with this fabric: That “cling” effect traps incoming — and outgoing — droplets. “That’s what you want — the cling is what’s important…And unlike other materials, polypropylene keeps its electrostatic charge in the humidity created when you breathe out

“Avoid masks with exhalation valves. Some cloth and disposable masks come with an exhalation valve at the front. The valve makes it easier to breathe out, but it also releases unfiltered air, so it doesn’t protect others if you’re contagious. And protecting others is the primary reason to wear a mask.

Contacts should monitor themselves by checking their temperature twice daily and watching for symptoms of COVID-19.

If you are diagnosed with COVID-19, a public health worker may call you to check-in on your health, discuss who you’ve been in contact with, and ask where you spent time while you may have been infectious and able to spread COVID-19 to others.

And despite drawing massive crowds, protests against police violence and racial injustice in Washington state weren’t among those clusters.

“We did have a rally in Bellingham, which is our county seat, and there was also a protest, and we have not been able to connect a single case to that rally or to the protest, and what we’re finding is in large part that’s due to the use of masks

14 cases were associated with a party of 100 to 150 people in early June. Subsequently, 15 more cases were associated with the original 14. So that one event spread to 29 people and 31 related employers,

“We’re finding that the social events and gatherings, these parties where people aren’t wearing masks, are our primary source of infection, …And then the secondary source of infection is workplace settings

“The concern is that because these younger people are having more mild symptoms, they are going to work sick, they are visiting with their parents and grandparents sick and they’re continuing to go to social events where they expose more and more people

“Tempe, Arizona (CNN) Walking along the streets this week in Tempe, Arizona, it was rare to see anyone wearing a mask. Patrons at a bar packed the entire space, as if the pandemic had suddenly dissipated. This despite the news that the state is one of the growing coronavirus hotspots in the country.

“The Arizona Department of Health Sciences on Friday announced there were 3,246 new Covid-19 cases, a record number reported on one day.
Arizona was one of the first states to reopen but the impact of the virus is everywhere in Tempe as some businesses are still shut down.

“When asked why he wasn’t wearing a mask, he replied, “I think masks are good, but they act as a placebo. I have family personally lost to coronavirus, so like, I should be wearing a mask, but not when I’m out with my friends.”

“Please keep yourself and your family safe. Always wear a mask in public even if you do not feel sick. Maintain physical distancing. Let’s work together to slow the spread of COVID-19. #MaskUpAZ,” the Arizona Department of Health Sciences said in a tweet on Friday. Phoenix has ordered residents to wear masks, one of more than a dozen cities across the state to announce local mask ordinances.

“Alarmed by the rapid increase in cases, more than 3,000 doctors and nurses sent a letter to Gov. Doug Ducey this week urging him to mandate masks. Ducey said he would not order a state mandate, instead leaving it up to local governments.

“To tell the whole world that basically I’m a social Darwinist if you die, I don’t care, I just want my beer and burger is, is really … I mean even kindergarteners have more empathy for other people.”

Big WHO Mixup: Asymptomatic Vs Presymptomatic: How The Virus Spreads : NPR

“Scientists at the World Health Organization were having a virtual press conference, a normal thing they do, just giving updates on the virus and how it’s moving around the world. And then something kind of confusing happens.

10 minute podcast and read full transcript of podcast at Source: >Asymptomatic Vs Presymptomatic: How The Virus Spreads : Short Wave : NPR

“Maria Van Kerkhove, who’s one of WHO’s top epidemiologists…

“listening to Van Kerkhove, you’d think – well, why did we lock down? Why do we wear masks? She left listeners with the impression that anyone without symptoms had a low chance of spreading the virus. And that’s wrong. We know – and there’s documented evidence for this – that the virus can be spread by people without symptoms.

“So this statement was reported on by news outlets. You know, the WHO is a major global health organization. What they say matters. And that scientist, Maria Van Kerkhove had to kind of walk this back.

“There was a lot of reaction and pressure from researchers and the public. People were saying that it was confusing at best or actually wrong at worst.

this mix-up with the WHO was partly about a distinction between asymptomatic people and what scientists are calling pre-symptomatic people.

“Asymptomatic, which is the group that Van Kerkhove was referring to, these are coronavirus carriers who are infected but they never end up showing any symptoms. They feel fine the whole time. And then there’s another group called pre-symptomatic. And these are people who’ve been infected. They haven’t gotten sick yet, but they will. And they can definitely spread the virus, we think, up to three days before they start showing symptoms. There’s plenty of evidence for this.

“But here’s the catch. You can’t tell if someone is asymptomatic or pre-symptomatic until one of them starts showing symptoms. And even if there are asymptomatic people out there that seem to be transmitting the virus less, there are documented cases where it’s happened. So what Van Kerkhove says she meant to say is that she has not seen evidence that people who are truly asymptomatic are out there effectively spreading the virus to a lot of other people.

“if you’re not actively sick, if you’re not running your nose everywhere – spreading coronavirus seems to require situations where people are hanging out really close together, mostly indoors, and doing things that project their voice and breath and spread respiratory droplets. So it’s situations like singing in a choir or panting during a dance class at the gym or shouting to be heard in a nightclub. These are all activities that have reportedly led to virus transmission.

 

Coronavirus Lockdowns Saved Millions Of Lives, Journal ‘Nature’ Reports : NPR

“When it comes to controlling the spread of the coronavirus, stay-at-home orders work. Two new studies published in the journal Nature say millions of lives have been saved worldwide.

“Samir Bhatt from Imperial College London, who worked on one of the papers published in Nature. His team analyzed infection and death rates across 11 European nations through early May. They estimate that 3 million more people in those countries would’ve died if lockdowns had not been put in place.

“Nature also just published a separate study from the Global Policy Lab at the University of California, Berkeley. That study analyzed lockdowns in China, South Korea, Iran, France, Italy and the United States. It found that the lockdowns in those six countries averted 62 million cases. In the U.S., for example, there were 360,000 cases by early April. Without lockdowns and other interventions, the researchers at Berkeley calculate that the U.S. would’ve had 14 times that number by April 6. Solomon Hsiang from Berkeley says these unprecedented shelter-in-place orders came at an extreme cost. And when governments ordered them, it was unclear exactly how great the social benefits would be.

Bhatt says this pandemic is far from over. And as much as people want to get back to normal, he cautions that people need to understand how much of a positive impact the lockdown measures have been having. 

COVID-19 Is Likely Airborne, Aerosol Scientist Says


Something has been bothering Kimberly Prather, PhD: everything she reads about COVID-19 points to a pathogen that travels through the air.

>Reducing transmission of Coronavirus, AAAS Science
(Sars-CoV-2 is the latest Coronavirus)

Full story of excerpts below on Medscape at Source: >COVID-19 Is Likely Airborne, Aerosol Scientist Says

A lot of the evidence has been pointing to aerosol transmission of respiratory viruses,”  Influenza can be passed through the air, as can the virus that causes SARS. “This particular virus, a lot of evidence is mounting. ..she’s been alarmed not to see the CDC or WHO come out with a strong statement that people could catch COVID-19 by breathing it in.

“…masks can play a major role in stopping that transmission. When you sing, the amount of droplets and aerosol that come out is really, in some respects, scary…When a person coughs or sneezes, they generate large droplets laden with viral particles. Those droplets are heavy and fall to the ground or a nearby surface pretty quickly, within seconds. They are still somewhat wet and sticky when they land.

“That’s where the 6-foot rule comes in… It’s based on studies of respiratory droplets conducted in the 1930s. Aerosols…can accumulate, remain infectious in indoor air for hours, and be easily inhaled deeply into the lungs this is a scary thing to be telling people. “I hesitate. I don’t want to freak people out.” She also believes knowledge is power.

“I have to say something because this could actually protect people,” she says. What airborne transmission means, she says, is that 6 feet is not far enough to stand apart. It also means we should probably be wearing masks a lot more often.

Is Ibuprofen Really Risky for Coronavirus Patients? – The NY Times. If you have covid fever the answer is not black and white, as usual.

Experts are puzzling over a claim made by France’s health minister.

>NSAIDs in patients with viral infections, including Covid-19: victims or perpetrators?

Full story of excerpts below at Source >Is Ibuprofen Really Risky for Coronavirus Patients?

When organizations can’t make up their minds, I get worried. France say this, the WHO changes its mind; it means the the answers are more complicated than black or white. In the case of ibuprofen and fevers we should be more deliberate than pill-popping for any pain.  I feel that the NY Times article source above really put the topic in great perspective. — DH

“for infectious disease specialists, the greater concern is that when Nsaids and acetaminophen reduce fever, patients may be more comfortable but their lower temperatures can short-circuit the body’s main defense against infection.

“Studies have found that if people infected with a variety of viruses and other microorganisms bring their fevers down, with Nsaids or with acetaminophen, their symptoms may last longer and they continue to shed virus for a longer time — meaning they may be contagious for longer periods

The immune system works better when the body’s temperature is higher, enabling it to more efficiently kill viruses and bacteria. Dozens of studies — in animals, reptiles and humans — have found that fever is beneficial in fighting infections.

“There is at least a theoretical danger the fever-reducers — including acetaminophen — may have a similar effect in patients ill with the coronavirus. Although there is no research yet, …it might be reasonable for a person infected with the coronavirus to avoid both kinds of painkillers…A drug like acetaminophen or ibuprofen can bring a fever down, but you don’t want to keep taking it constantly.

“..an 18th-century English physician, Dr. Thomas Sydenham: “Fever is nature’s engine which she brings to the battlefield to vanquish her enemies.”

Good news for a change. Coronavirus Antibody Testing Shows Lower Fatality Rate For Infection : Shots – Health News : NPR


Tests for the immune response to the coronavirus are revealing thousands of people who were infected but never got severely ill. The findings suggest the virus is less deadly than it first appeared.

Full story of excerpts below at Source: >Coronavirus Antibody Testing Shows Lower Fatality Rate For Infection : Shots – Health News : NPR

Mounting evidence suggests the coronavirus is more common and less deadly than it first appeared. The evidence comes from tests that detect antibodies to the coronavirus in a person’s blood rather than the virus itself.

The tests are finding large numbers of people in the U.S. who were infected but never became seriously ill. And when these mild infections are included in coronavirus statistics, the virus appears less dangerous. …But even a virus with a fatality rate less than 1% presents a formidable threat.

“That is many times more deadly than seasonal influenza,” ….Studies suggest a healthy young person’s chance of dying from an infection is less than 1 in 1,000. But for someone in poor health in their 90s, it can be greater than 1 in 10...And that means different states in the U.S. should expect different infection fatality rates.

 

What We Can Learn Today From An Ebola Outbreak : NPR


“It sounds like a movie plot: police discover the body of a young man who’s been murdered. The body tests positive for a deadly infectious disease. Authorities trace the killing to a gang. They race to find the gang members, who may also be incubating the virus. This week on Hidden Brain, we revisit our 2016 story about disease, panic, and how a public health team used psychology to confront an epidemic.

“This scenario actually unfolded in the West African nation of Liberia in 2015. And what followed was a truly unconventional effort by epidemiologists to stop a new Ebola outbreak. It was all done in an effort to overcome what can be the biggest obstacle in public health: a severe lack of trust.

What It Takes To Be A Contact Tracer : NPR Do you have empathy? Welcome to the new economy


Riding the Tidal Wave of the Coming Public Health Economy

5 min podcast >A Day In The Life Of A Coronavirus Contact Tracer

Are the US and state governments being dragged kicking and screaming into an unprecedented massive investment for contact tracing? As governments extol the quick recovery from the virus pandemic, experts keep talking of repeating infection waves since our fragmented bureaucracy cannot get a handle what the virus is really doing in this country until massive resources are committed to tracking it down. Fighting over costs will be swept away into absolute submission and a new economy. Other countries and a few States are leading the way. Watch for new remote and compassionate footwork jobs to start appearing. Contract tracing needs empathy. Everyone is frightened when contacted. — DH

“NPR’s Michel Martin speaks with John Welch, the director of partnerships & operations for Massachusetts’ COVID-19 response at Partners In Health, about their contact tracing program and training.

“Public health experts say that one of the keys to safely lifting stay-at-home orders around the country is contact tracing. So we wanted to spend some time now learning more about what it takes to implement a statewide contact tracing program and how people are being trained for this…

“It is exactly as you described it, a ramp-up at this stage, a lot of quick hiring and, you know, in-depth training and making sure we have the right people who have the right skills but then most importantly people who have the patience and the empathy to listen. They’re reaching out to people who are in crisis and some people who are in acute crisis sort of superimposed on a chronic crisis of maybe poverty or marginalization.

“And those individuals need extra time and not only need it – they deserve it. So these contact tracers are balancing the need for understanding how to do the work while also just being a gentle ear…You know, first and foremost, we’re very sensitive to a variety of populations who might not be interested in anyone who’s sort of affiliated with state government reaching out to them.

“And we’re very sensitive to that and want all those individuals to know that this is a public health activity, that their information is very safe with us and that our interest is in helping them and keeping their families and friends safe.But then the folks who we do get in touch with are actually by and large relieved, you know.

We live in a world now, in this country where to receive health care, you’ve got to go and find it. And this activity is care coming to find you. So while contact tracing is an important epidemiological tool, it’s also an act of caring. And I think by and large people are really relieved to receive that phone call.

4 minute podcast, some excerpt below and much more at >We Asked All 50 States About Their Contact Tracing Capacity. Here’s What We Learned :
“We are investigating the relentless math of containing the pandemic. The next phase of fighting the coronavirus leans heavily on contact tracing. And numbers will measure the result. How many people have tested positive? How many people have they recently contacted? And how quickly can those people be quarantined?

“To establish those numbers, the United States needs a very large workforce of people to do contact tracing. Are we hiring enough people? NPR’s Selena Simmons-Duffin has spent the last week putting that question to officials in every single state, along with Puerto Rico and the District of Columbia. And she’s on the line. Selena, good morning.

SELENA SIMMONS-DUFFIN, BYLINE: Good morning, Steve.

INSKEEP: What’d you find?

SIMMONS-DUFFIN: So we were able to get data from 41 states. And the total they currently have added up to 7,300. Most states said they were planning a hiring surge. And after that, we will have 35,600. This is a snapshot from the past week. And a lot is in flux. But that’s our best estimate for what’s planned, more than 35,000 contact tracers nationally.

INSKEEP: Which sounds like a lot. But is that enough?

SIMMONS-DUFFIN: The short answer is not even close. Yesterday on the show, you had some influential former officials saying the country needs 180,000 total. Other estimates have put the number needed at 100,000. Here’s what Tom Frieden, former CDC director, told me about the totals we found.

TOM FRIEDEN: It’s a start. I think an increasing number of health departments around the country recognize the need to substantially scale up activities.

Coronavirus patients describe symptoms that last a month or more

“Some patients say they’re struggling to get back to their regular lives a month after getting diagnosed with the coronavirus. They say they’re still experiencing symptoms intermittently. Doctors say there’s still unknowns because the disease is still a “baby virus.

”There’s a wide variation among patients in how long symptoms last. Teresa Rodriguez knew something was wrong when she lost her sense of smell. She was cooking dinner with her daughter, and it hit her that something was off. The following morning, on March 23, she woke up feeling extremely tired, and her health deteriorated quickly from there.

“By the next week, I was totally immobilized,” she said. Once she had the strength to get out of bed, Rodriguez, who is in her early 50s, drove to the nearest community Covid-19 testing site in the San Francisco Bay Area, staffed by the Alphabet company Verily. A few days later, the test came back positive.

“It’s now been more than a month since she started experiencing symptoms, and she’s still battling a lingering headache, cough and fatigue. Rodriguez is just starting to feel like she can move around her home, but she’s still not feeling like her usual energetic self.

“She’s had plenty of colds and flus in the past, and described Covid-19 as “far worse.” What has surprised her the most, aside from the severity of the symptoms, is the longevity. She’s far from alone. Patients diagnosed or suspected to have Covid-19 are posting via online forums and on social media about symptoms that feel endless. Many say it comes in waves.

“They start feeling better after a few weeks, but it hits them again and persists. These patients say they’re in the middle camp between those who experience the virus like a mild cold or flu, and those who are so sick they end up at the hospital. It has been a frustrating experience, they say, especially for those who are struggling to get back to work and care for their kids after more than a month of feeling under the weather.

Call For Public Health Investment In Next Congressional COVID-19 Aid Package. The curve needs to be going down, not flat… : NPR

(If we put on flat hats, can we go out then?)

11 Minute Podcast and full story at >Call For Public Health Investment

“NPR’s Steve Inskeep talks to Scott Gottlieb, ex-head of the FDA, and Andy Slavitt, who led the Centers for Medicare and Medicaid, about the letter they wrote to Congress with a plan to reopen the U.S.

What will it take for Americans to get back to work? Two veteran voices in American health care are offering answers…

“…we’re going to have to have an aggressive system in place to try to identify positive cases through testing. And when we do find people who are infected with coronavirus, we have to have a system in place to allow them to self-isolate so that they don’t continue to spread infection. That’s going to require us to hire many more public health workers to do the contact tracing, basically the blocking and tackling of public health work, where you identify people, and then you go out and talk to them and then interview people who may have been in contact with them and offer them testing.

“What we’re going to be doing as we enter into the fall, in particular, as coronavirus starts to collide with flu season and we face the risk of large outbreaks and maybe another epidemic heading into the winter, what we’re going to be trying to do is get ahead of this and put in place enough layers of protection that you mitigate spread. We’re never going to be able to reduce all spread…

“We’re at a point right now where we’re seeing cases across the country plateau, but we still have 30,000 cases a day that we’re recording. There’s many more that we’re not capturing. We’re still having 2,000 deaths a day. So we’ve plateaued, but we haven’t really seen the sustained declines that we think we need in order to really safely start to restart economic activity. In fact, really, when you look at it, only about five states have shown sustained reductions in new cases that meet the criteria set out by the administration in terms of when you would contemplate restarting activity. So the best thing we can do to get consumers back and get the economy vibrant again is give people confidence that we’ve controlled this epidemic, the virus isn’t circulating widely and people’s risk of contracting it if they go out is low again.”
