Coronavirus News: Live Updates – The New York Times

At least 25,600 residents and workers have died from the coronavirus at nursing homes and other long-term care facilities for older adults in the United States, according to a New York Times database.

While just about 10 percent of the country’s cases have occurred in long-term care facilities, deaths related to Covid-19 in these facilities account for a third of the country’s pandemic fatalities. And in about a dozen states, including Maryland, Oregon and Colorado, such facilities account for an even larger segment — more than half — of deaths.

In the absence of comprehensive data from some states and the federal government, The Times has been assembling its own database of coronavirus cases and deaths at these facilities.

A Drug Cocktail Hastens Recovery in Some Coronavirus Patients

With vaccines still months, maybe years, into the future, researchers are rushing to determine whether existing drugs can be used to treat the coronavirus. In the United States, only one — remdesivir — has been shown to be effective in speeding recovery.

In the new study, published in The Lancet, researchers at six public hospitals in Hong Kong and the University of Hong Kong followed 127 adults with Covid-19, including 86 on the three-drug cocktail and 41 in a comparison group.

Their study was a preliminary Phase 2 trial, intended to see if a treatment works. (It does not determine whether the treatment is better than other options, but there are few other options for the coronavirus.)

The patients who were started on the cocktail within seven days of having their first symptoms stopped shedding the virus — meaning they were recovering and no longer infectious — earlier than patients

F.D.A. Paves Way for Home Testing of Coronavirus

In a move that could significantly expand the nation’s testing capacity, the Food and Drug Administration has posted new guidelines that could pave the way for millions of people to test themselves for the coronavirus at home.

The guidelines allow companies to develop and market testing kits with the tools to swab their noses and mail the specimens to any lab in the country.

Access to tests has been improving, but nationwide testing shortages continue to hamper the ability of health authorities to identify and isolate people who are infected.

The F.D.A. said it hoped the new guidelines, posted on its site on Wednesday

In the Fight to Treat Coronavirus, Your Lungs Are a Battlefield

Ventilators have become the single most important piece of medical equipment for critically ill coronavirus patients whose damaged lungs prevent them from getting enough oxygen to vital organs. The machines work by forcing air deep into the lungs, dislodging the fluid and accumulated pus that interfere with the exchange of oxygen, a process orchestrated by tiny air sacs known as alveoli.

It’s still not clear how lungs are affected by Covid-19.

Lungs are complex organs that deliver oxygen to the bloodstream and keep organs functioning.

Human lungs are spongy vessels made up of millions of microscopic, balloon-shaped air sacs called alveoli, the workhorse of the respiratory system where the exchange of gases takes place.

A single alveolus, no bigger than the width of a human hair, is ringed by a mesh of tiny capillaries that transport oxygen to the bloodstream.

A single alveolus, no bigger than the width of a
