In Nick Cordero’s Death, a Reminder of Covid-19’s Unknowns
“The idea that ‘I’m young, I’ll be fine’ is not an idea that we can completely subscribe to,” said Dr. Utibe Essien, a physician and health equity researcher at the University of Pittsburgh.Amanda Kloots, Mr. Cordero’s wife, has said that he had no known pre-existing conditions that might have worsened the course of his disease.
Regeneron Starts Phase 3 Trial For Coronavirus Antibody Cocktail
Regeneron Pharmaceuticals has started late-stage clinical trials evaluating REGN-COV2, its investigational double antibody cocktail for the treatment and prevention of COVID-19. A Phase 3 trial will evaluate REGN-COV2's ability to prevent infection among uninfected people who have had close exposure to a COVID-19 patient.
Coronavirus vaccine research: Scientists pursue RNA to trigger covid immune response
In the global race to beat back the coronavirus pandemic, scientists in Britain, Germany, China and the United States are pushing to develop, and possibly manufacture, vaccines in a completely new way. This promising — but unproven — new generation of vaccine technologies is based on deploying a tiny snip of genetic code called messenger RNA to trigger the immune system. It has never before been approved for use.
The Fullest Look Yet at the Racial Inequity of Coronavirus
Fever checks can’t catch all Covid-19 cases. Smell tests might help
Unfortunately, temperature checks could well join the long list of fumbled responses to the pandemic, from the testing debacle to federal officials’ about-face on masks. Because many contagious people have no symptoms, using temperature checks to catch them is like trying to catch tennis balls in a soccer net: way too many can get through.
Coronavirus Survivors: Here’s What Recovery May Look Like
Coronavirus: Immunity may be more widespread than tests suggest
For every person testing positive for antibodies, two were found to have specific T-cells which identify and destroy infected cells. This was seen even in people who had mild or symptomless cases of Covid-19. But it's not yet clear whether this just protects that individual, or if it might also stop them from passing on the infection to others.
Oregon Coronavirus Among Under 10 Kids Grows Fivefold, to Nearly as Many Cases as People Over 80
The number of COVID-19 cases among children under the age of 10 in Oregon was more than five times greater at the end of June than it was one month earlier. Data shared by the Oregon Health Authority said 319 children under 10 had confirmed or presumptive positive cases by Tuesday, June 30. At the end of May, only 58 cases within that age group had been reported to the OHA.
Pfizer reports encouraging early covid-19 vaccine data
Remdesivir: How does the drug treat coronavirus and is it available in the UK?
Health officials in the US have announced that the Trump administration has bought almost the entire world’s stock of the Covid-19 drug remdesivir. Despite its ability to shorten the recovery times (by around four days) of some coronavirus patients, remdesivir has not been found to significantly improve an individual’s chances of surviving the disease.
Coronavirus tests, unpredictable pricing
Two Friends in Texas Were Tested for Coronavirus The emergency room charged Mr. Harvey $199 in cash. Ms. LeBlanc, who paid with insurance, was charged $6,408. “I assumed, like an idiot, it would be cheaper to use my insurance than pay cash right there,” Ms. LeBlanc said. “This is 32 times the cost of what my friend paid for the exact same thing.”
U.S. Coronavirus Testing Could Fail Again
Studies find nearly 300 kids with inflammatory condition tied to Covid-19
This coronavirus mutation has taken over the world. Scientists are trying to understand why.
A mutation that seems trivial could be making the virus spread more easily. At least four laboratory experiments suggest that the mutation makes the virus more infectious, although none of that work has been peer-reviewed. Another unpublished study led by scientists at Los Alamos National Laboratory asserts that patients with the G variant actually have more virus in their bodies, making them more likely to spread it to others.
Not just the lungs: Covid-19 attacks like no other ‘respiratory’ virus
As the pandemic grew from an outbreak affecting thousands in Wuhan, China, to some 10 million cases and 500,000 deaths globally as of late June, the list of symptoms has also exploded. The Centers for Disease Control and Prevention constantly scrambled to update its list in an effort to help clinicians identify likely cases.
CDC says COVID-19 cases in U.S. may be 10 times higher than reported
The true number of Americans who've been infected with COVID-19 may top 20 million, according to new estimates from the Centers for Disease Control and Prevention. The assessment comes from looking at blood samples across the country for the presence of antibodies to the virus. For every confirmed case of COVID-19, 10 more people had antibodies
Air conditioning and Covid-19: The scientific factors you should know
Air conditioning systems partially filter coronavirus-containing viral particles, alter airflow patterns, and often, recirculate indoor air — all shifts that can influence Covid-19 transmission. A.C. also increases ventilation within a stagnant room or building, which can disperse coronavirus-containing viral droplets, and lower the chance of infection.

Mask wearing made COVID death rates 100 times lower than projected
“We looked at the data from 198 countries around the world, and we looked at mortality from coronavirus,” says lead author Christopher Leffler, a physician and professor at Virginia Commonwealth University. “What we found is that the countries that introduced masks quickly—that is, before the outbreak had much of a chance to spread within their country—had a much lower mortality.”

Bars, Strip Clubs and Churches: U.S. Virus Outbreaks Enter Unwieldy Phase
New known virus cases were on the rise in 23 states on Monday as the outlook worsened across much of the nation’s South and West. Hospitalizations for the coronavirus reached their highest levels yet in the pandemic in Arizona and Texas, and Missouri reported its highest single-day case totals over the weekend.
COVID-19 Can Cause Loss of Smell, And Scientists Finally Discovered Why
One of the most common causes of smell loss is a viral infection, such as the common cold, sinus or other upper respiratory tract infections. Those coronaviruses that don't cause deadly diseases, such as COVID-19, SARS and MERS, are one of the causes of the common cold and have been known to cause smell loss.

How one covid-19 vaccine race went from Oxford to an Italian lab overseeing trials
A lab outside Rome took “seed stock” produced at Oxford. Now U.S. and European officials are showing signs of support. That vaccine, like all the others designed to combat the pandemic, remains unproved. But it is further along in the trial process than the others, and it has turned into the West’s best — and perhaps only — chance to have a viable vaccine before the end of the year.

Consumer spending comes back ‘with a vengeance’ in May
Despite a recent jump in retail sales, a decline in spending by the wealthy could contribute to an economic slowdown. Researchers tracking spending patterns using credit card data found that people at the bottom of the income bracket are spending nearly as much as before the pandemic, while the wealthy are not matching them.
Coronavirus: why it’s dangerous to blindly ‘follow the science’ when there’s no consensus yet
In the face of the virus emergency, research standards have been relaxed to encourage faster publication and mistakes become inevitable. This is risky. Ultimately, if expert advice on the pandemic turns out to be wrong, it will have dire consequences for how reliable scientific evidence is treated in other policy areas, such as climate change.

Coronavirus: Dexamethasone proves first life-saving drug
A cheap and widely available drug can help save the lives of patients seriously ill with coronavirus. The low-dose steroid treatment dexamethasone is a major breakthrough in the fight against the deadly virus, UK experts say. The drug is part of the world's biggest trial testing existing treatments to see if they also work for coronavirus.
Florida dogs being trained to sniff out coronavirus
The virus-sniffing dogs could prove useful in areas where people congregate in large groups. Jeff Minder is a former survival instructor for the Air Force and has a patented 50-point dog training system and saw a need. Uzi, a Belgium Malinois, is his personal dog and has compiled a record more accurate than testing.
How Exactly Do You Catch Covid-19? There Is a Growing Consensus
It’s not common to contract Covid-19 from a contaminated surface, scientists say. And fleeting encounters with people outdoors are unlikely to spread the coronavirus. Instead, the major culprit is close-up, person-to-person interactions for extended periods. Crowded events, poorly ventilated areas and places where people are talking loudly—or singing, in one famous case—maximize the risk.
Covid-19 can damage lungs of victims beyond recognition, expert says
Patients with underlying conditions were 12 times as likely to die of covid-19 as otherwise healthy people, CDC finds
People with underlying medical conditions such as heart disease and diabetes were hospitalized six times as often as otherwise healthy individuals infected with the novel coronavirus during the first four months of the pandemic, and they died 12 times as often, according to a federal health report Monday.
White House pressure for a vaccine raises risk the U.S. will approve one that doesn’t work
President Donald Trump has promised that there will be a coronavirus vaccine before the year is out. But public health experts are growing increasingly worried that the White House will pressure regulators to approve the first vaccine candidate to show promise — without proof that it provides effective, reliable protection against the virus.

Nearly 160 coronavirus vaccines are in the works. Here’s a closer look at the science
The global race for a coronavirus vaccine involves a few basic approaches. Some have been around for decades, others are being tried for the first time. Although all approaches are distinct, they are based on a few simple strategies. Some have been around for years; others are being tested for the first time.
Chronic coronavirus: These patients have been sick for weeks, but doctors don’t know why
Melanie Montano, 32, developed a fever, cough, stomach problems, and lost her sense of taste and smell like other sufferers of the novel coronavirus. Unlike most of them, though, her symptoms never went away. Dr's are unsure whether those symptoms suggest virus is still alive in the body and creating continued havoc, or whether it has come and gone, leaving a lingering immune or inflammatory response that makes people continue to feel sick.

During the 1918 Flu’s Second Spike, Americans Resisted Social Distancing. Could That Happen Again?
If history is any indicator, attempts to reinstitute social distancing measures to flatten a potential second wave of the virus could face more opposition than the initial lockdowns. The widespread business closures and mask ordinances implemented during the 1918 influenza pandemic weren’t especially popular.

"This is exciting news about the value of masking to prevent Covid-19," said Clay Goddard, the county's director of health. "We are studying more closely the details of these exposures, including what types of face coverings were worn and what other precautions were taken to lead to this encouraging result."
Coronavirus hospitalizations on the rise in nine states since Memorial Day
At least nine U.S. states have experienced a rise in hospitalizations due to Covid-19 since Memorial Day, with some reporting their highest-ever hospitalizations throughout the pandemic in recent days. Outbreaks among America’s farm workers are also on the rise, moving advocates to call for the federal government to require personal safety measures.

What kind of masks should my kid wear
To encourage young children to wear a face mask while in public, some pediatricians have suggested that parents name, talk to it and even pretend to feed their child’s mask. While it may feel silly, doctors say that kids quickly adapt the same attitudes as adults, including for the use of face masks.
WHO scrambles to clarify comments on asymptomatic coronavirus spread, says much is still unknown
The World Health Organization clarified its comments that asymptomatic spread is “very rare” after coming under fire by academics and epidemiologists for misleading the public. While more transmission does happen among symptomatic individuals, a risk of transmission is present for all, an official explained.

Coronavirus likely arrived in US in December, before WHO was informed
On January 19, a 35-year-old man walked into an urgent care center in Snohomish County, Washington, with a cough and a fever. Four days earlier, he had returned from a trip to Wuhan, China. But he was almost certainly not the true first. Since then, a growing number of puzzle pieces have revealed a different picture of the beginning of the country's outbreak.
Can air-conditioning help spread coronavirus?
As the weather heats up and the country opens up, scientists are trying to figure out how much effect air-conditioned air will have in spreading—or curtailing—the virus. There are multiple factors to consider, such as how AC could enable the circulation of viral particles in the air and increase the speed and distance they travel.

Genes May Leave Some People More Vulnerable to Severe Covid-19
Variations at two spots in the human genome are associated with an increased risk of respiratory failure in patients with Covid-19, the researchers found. One of these spots includes the gene that determines blood types. Having Type A blood was linked to a 50 percent increase in the likelihood that a patient would need to get oxygen or to go on a ventilator, according to the new study.

K sheds light on the variation behind R. “Some [infectious] people might generate a lot of secondary cases because of the event they attend, for example, and other people may not generate many secondary cases at all,” said Dr Adam Kucharski. “K is the statistical value that tells us how much variation there is in that distribution.”
Predictive power of mathematical modelling and the risk of a second wave
Neuroscientist Karl Friston, of University College London, builds mathematical models of human brain function. Lately, he’s been applying his modelling to Covid-19. He says, our approach, which borrows from physics and in particular the work of Richard Feynman, goes under the bonnet. It attempts to capture the mathematical structure of the phenomenon – in this case, the pandemic – and to understand the causes of what is observed.
Coronavirus May Be a Vascular Disease, Which Explains Everything
Data shows us that mysterious symptoms attributed to COVID-19, like coronavirus related strokes and Covid toes, are symptoms of an impairment in blood circulation. Add in the fact that 40% of the deaths from Covid-19 are related to cardiovascular complications, the disease starts to look like a vascular infection.
COVID-19 misinformation and the election are colliding
Since the coronavirus outbreak, all three networks have worked to promote appropriate sources of health information and pull down content that could harm users. However, they have traditionally shied from removing false information that is politically charged. As health misinformation becomes increasingly politicized, they may be forced to take a stance.
