Preventing dangerous blood clots from COVID-19 is proving tricky

For some severely ill COVID-19 patients, the struggle to take in enough air is not only due to having fluid-clogged lungs. The quest for oxygen also is stymied by a plethora of blood clots. As it’s become clear that excessive clotting can be a complication of a serious coronavirus infection, there’s been debate over how…

COVID-19 case clusters offer lessons and warnings for reopening

Several months into the COVID-19 pandemic, countries are looking for ways to restart their economies, public health officials are looking to guide safe reopening and people are eagerly looking to escape cabin fever.

A low-cost steroid may save the lives of some people who are on ventilators or supplemental oxygen because of COVID-19, preliminary data from a large clinical trial suggest.

COVID-19 lockdowns helped people get more, but not necessarily better, sleep

Lockdowns haven’t just curbed coronavirus transmission — they’ve also helped people get more sleep (SN: 6/9/20). Two studies, both published June 10 in Current Biology, report that people began sleeping more and more regularly every night after countries imposed stay-at-home orders to slow the spread of the coronavirus. But that sleep may not have been…

The FDA has canceled emergency use of hydroxychloroquine for COVID-19

Hydroxychloroquine and chloroquine no longer have the U.S. Food and Drug Administration’s blessing for use against coronavirus infections when given outside of a clinical trial. In March, the agency authorized using the malaria drugs for hospitalized patients with COVID-19 who couldn’t participate in clinical trials. But the legal criteria for issuing an emergency use authorization…

The successful transplantation of a donor’s lungs to a severely ill COVID-19 patient may offer others with irreversibly damaged lungs a means of survival.

No, you can’t hear the difference between sick and healthy coughs

No, you can’t hear the difference between sick and healthy coughs

An aisle over in the grocery store, someone lets out a nasty cough, and you shudder. “That person sounds really sick,” you think as you head in the opposite direction. A new study may prompt you to think again. Humans can’t hear a difference between the cough of someone with an infection and someone with…
