Can New York hold off a second wave of the coronavirus?

Can New York hold off a second wave of the coronavirus?

The New York Times reports: Health experts in New York City thought that coronavirus cases would be rising again by now. Their models predicted it. They were wrong. New York State has managed not only to control its outbreak since the devastation of the early spring, but also to contain it for far longer than even top officials expected. Now, as other places struggle to beat back a resurgence and cases climb in former success-story states like California and Rhode…

Southeast Asia detects mutated coronavirus strain sweeping the world

Southeast Asia detects mutated coronavirus strain sweeping the world

Bloomberg reports: Southeast Asia is facing a strain of the new coronavirus that the Philippines, which faces the region’s largest outbreak, is studying to see whether the mutation makes it more infectious. The strain, earlier seen in other parts of the world and called D614G, was found in a Malaysian cluster of 45 cases that started from someone who returned from India and breached his 14-day home quarantine. The Philippines detected the strain among random Covid-19 samples in the largest…

How to use ventilation and air filtration to prevent the spread of coronavirus indoors

How to use ventilation and air filtration to prevent the spread of coronavirus indoors

Open windows are the easiest way to ventilate a room. Justin Paget / Digital Vision via Getty Images By Shelly Miller, University of Colorado Boulder The vast majority of SARS-CoV-2 transmission occurs indoors, most of it from the inhalation of airborne particles that contain the coronavirus. The best way to prevent the virus from spreading in a home or business would be to simply keep infected people away. But this is hard to do when an estimated 40% of cases…

FDA clears saliva test for Covid-19, opening door to wider testing

FDA clears saliva test for Covid-19, opening door to wider testing

STAT reports: The Food and Drug Administration on Saturday authorized emergency use of a new and inexpensive saliva test for Covid-19 that could greatly expand testing capacity. The new test, which is called SalivaDirect and was developed by researchers at the Yale School of Public Health, allows saliva samples to be collected in any sterile container. It is a much less invasive process than the nasal swabs currently used to test for the virus that causes Covid-19, but one that…

Long after the fire of a Covid-19 infection, mental and neurological effects can still smolder

Long after the fire of a Covid-19 infection, mental and neurological effects can still smolder

STAT reports: Early on, patients with both mild and severe Covid-19 say they can’t breathe. Now, after recovering from the infection, some of them say they can’t think. Even people who were never sick enough to go to a hospital, much less lie in an ICU bed with a ventilator, report feeling something as ill-defined as “Covid fog” or as frightening as numbed limbs. They’re unable to carry on with their lives, exhausted by crossing the street, fumbling for words,…

Postal Service warns 46 states their voters could be disenfranchised by delayed mail-in ballots

Postal Service warns 46 states their voters could be disenfranchised by delayed mail-in ballots

The Washington Post reports: Anticipating an avalanche of absentee ballots, the U.S. Postal Service recently sent detailed letters to 46 states and D.C. warning that it cannot guarantee all ballots cast by mail for the November election will arrive in time to be counted — adding another layer of uncertainty ahead of the high-stakes presidential contest. The letters sketch a grim possibility for the tens of millions of Americans eligible for a mail-in ballot this fall: Even if people follow…

The plan that could give us our lives back

The plan that could give us our lives back

Robinson Meyer and Alexis C. Madrigal write: Michael Mina is a professor of epidemiology at Harvard, where he studies the diagnostic testing of infectious diseases. He has watched, with disgust and disbelief, as the United States has struggled for months to obtain enough tests to fight the coronavirus. In January, he assured a newspaper reporter that he had “absolute faith” in the ability of the Centers for Disease Control and Prevention to contain the virus. By early March, that conviction…

The real coronavirus death toll in the U.S. has already surpassed 200,000

The real coronavirus death toll in the U.S. has already surpassed 200,000

The New York Times reports: Across the United States, at least 200,000 more people have died than usual since March, according to a New York Times analysis of estimates from the Centers for Disease Control and Prevention. This is about 60,000 higher than the number of deaths that have been directly linked to the coronavirus. As the pandemic has moved south and west from its epicenter in New York City, so have the unusual patterns in deaths from all causes….

Population immunity is slowing down the pandemic in parts of the U.S.

Population immunity is slowing down the pandemic in parts of the U.S.

MIT Technology Review reports: The large number of people already infected with the coronavirus in the US has begun to act as a brake on the spread of the disease in hard-hit states. Millions of US residents have been infected by the virus that causes covid-19, and at least 160,000 are dead. One effect is that the pool of susceptible individuals has been depleted in many areas. After infection, it’s believed, people become immune (at least for months), so they…

Russia doesn’t really know whether its Covid vaccine works

Russia doesn’t really know whether its Covid vaccine works

Max Nisen writes: Russia is prematurely declaring victory in the race for a vaccine against Covid-19, with potentially dangerous consequences for the Russian population. President Vladimir Putin says his government has approved a vaccine and will start inoculating teachers and medical workers this month, before embarking on a mass vaccination effort in the fall. Yet the shot is not backed by evidence from a complete phase 3 trial, the gold standard for confirming safety and efficacy. Deciding to move ahead…

‘A smoking gun’: Infectious coronavirus retrieved from hospital air

‘A smoking gun’: Infectious coronavirus retrieved from hospital air

The New York Times reports: Skeptics of the notion that the coronavirus spreads through the air — including many expert advisers to the World Health Organization — have held out for one missing piece of evidence: proof that floating respiratory droplets called aerosols contain live virus, and not just fragments of genetic material. Now a team of virologists and aerosol scientists has produced exactly that: confirmation of infectious virus in the air. “This is what people have been clamoring for,”…

Antibody drugs could be one of the best weapons against Covid-19. But will they matter?

Antibody drugs could be one of the best weapons against Covid-19. But will they matter?

STAT reports: From the moment Covid-19 emerged as a threat, one approach to making drugs to treat or prevent the disease seemed to hold the most promise: They’re known as monoclonal antibodies. Now, scientists are on the brink of getting important data that may indicate whether these desperately needed therapies could be safe and effective. Clinical trials involving a pair of antibodies developed by Regeneron Pharmaceuticals will read out early results in September. A separate effort from Eli Lilly could…

Why America’s window of opportunity to beat back Covid-19 is closing

Why America’s window of opportunity to beat back Covid-19 is closing

Helen Branswell writes: The good news: The United States has a window of opportunity to beat back Covid-19 before things get much, much worse. The bad news: That window is rapidly closing. And the country seems unwilling or unable to seize the moment. Winter is coming. Winter means cold and flu season, which is all but sure to complicate the task of figuring out who is sick with Covid-19 and who is suffering from a less threatening respiratory tract infection….

The greatest weakness of American men? Fear of looking weak

The greatest weakness of American men? Fear of looking weak

Alex Abad-Santos writes: Fellas, is it gay to not die of a virus that turns your lungs into soggy shells of their former selves, drowning you from the inside out? Is wearing a mask to avoid death part of the feminization of America? Is it too emasculating to wear a mask to protect the others around you? Does staying alive make you feel weak? According to many American men, yeah. Poll after poll, most recently a Gallup poll from July…

Does coronavirus linger in the body? What we know about how viruses in general hang on in the brain and testicles

Does coronavirus linger in the body? What we know about how viruses in general hang on in the brain and testicles

Are there places in the body where SARS-CoV-2 can hide from the immune system? fotograzia / Getty Images By William Petri, University of Virginia As millions of people are recovering from COVID-19, an unanswered question is the extent to which the virus can “hide out” in seemingly recovered individuals. If it does, could this explain some of the lingering symptoms of COVID-19 or pose a risk for transmission of infection to others even after recovery? I am a physician-scientist of…

America tops 5 million confirmed virus cases, to Europe’s alarm

America tops 5 million confirmed virus cases, to Europe’s alarm

The Associated Press reports: With confirmed coronavirus cases in the U.S. hitting 5 million Sunday, by far the highest of any country, the failure of the most powerful nation in the world to contain the scourge has been met with astonishment and alarm in Europe. Perhaps nowhere outside the U.S. is America’s bungled virus response viewed with more consternation than in Italy, which was ground zero of Europe’s epidemic. Italians were unprepared when the outbreak exploded in February, and the…
