Vietnam, a country of 97 million people, has not reported a single coronavirus-related death and on Saturday had just 328 confirmed cases, despite its long border with China and the millions of Chinese visitors it receives each year.

The best COVID-19 response in the world

The nose is the probable starting point for COVID-19 infections. Richard Boucher and Ralph Baric at the University of North Carolina at Chapel Hill and their colleagues tracked the ease with which the new coronavirus infects various cell types in the respiratory tract. The researchers found a gradient of infectivity that decreases from the upper to the lower respiratory tract: the most easily infected cells are in the nasal cavity, and the least easily infected deep in the lungs.

World Health Organization officials have renewed praise for China in response to the COVID-19 outbreak, citing its “openness” to the prospect of scientific inquiries involving foreign experts into the origins of the novel coronavirus.

Nearly 1 in 7 people in New York who were randomly tested for coronavirus antibodies turned out to have them, Governor Andrew Cuomo announced today (April 23). In New York City, the number is even higher: About 1 in 5 people tested positive for antibodies to SARS-CoV-2. If those early results translate to the rest of the New York population, that would mean about 2.7 million people across the state would have been infected.

It’s responsible for infecting more than five million across the world and now we can see exactly what it looks like in minute detail. Scientists and CGI specialists at Visual Science have created the most scientifically accurate model of the SARS-CoV-2 virus and experts have been blown away by the “striking” precision.

To better understand how social environments shape human health, a team of researchers dug into the literature, analyzing studies on humans and animals.

Dining out right now will come with certain risks. Here’s what you can do to keep yourself and others around you safe.

President Jair Bolsonaro has refused to take the coronavirus pandemic seriously, even though more than 17,500 Brazilians have already died from the virus. And the number of cases continues to grow exponentially.

Raul Razo and three buddies were knocking out their daily situps and pushups in their 72-man tank at the Harris County Jail in late March when they were overcome. All four were gasping for air. “Uno por uno. Uno por uno,” Razo told his wife in a phone call punctuated by dry coughs. One by one they’d abandoned their workout and slogged off to their bunks.

A film featuring a known anti-vaxxer pushing conspiracy theories and false claims about the novel coronavirus, including attacking vaccines, has racked up more than 9 million views on YouTube. Additionally, the video and its reuploads have tallied more than 16 million Facebook engagements. The spread of the film -- called “Plandemic” -- through reuploads on YouTube shows the platform’s continuing issues with enforcing its policies against coronavirus misinformation during this public health crisis.

Kidney damage, blood clots and even "covid toes" prompt reassessment of the disease and how it should be treated.

The persistent myth can be put to bed.

Reopening the economy will involve coronavirus-testing programs and contact tracing similar to those used in the adult film industry for HIV.

Los Angeles County's stay-at-home orders will 'with all certainty' be extended for the next three months, Public Health Director Barbara Ferrer said.

The coronavirus that causes COVID-19 could become endemic like HIV, the World Health Organization said on Wednesday, warning against any attempt to predict how long it would keep circulating and calling for a "massive effort" to counter it.

Some people die from covid-19, and others who are infected don’t even show symptoms. But scientists still don’t know why. Now consumer genomics company 23andMe is going to offer free genetic tests to 10,000 people who’ve been hospitalized with the disease, hoping to turn up genetic factors that could point to an answer.

Inequality made historical pandemics ‘worse than they had to be’

Over a third of patients treated for COVID-19 in a large New York medical system developed acute kidney injury, and nearly 15% required dialysis, U.S. researchers reported on Thursday.

Immune warriors known as T cells help us fight some viruses, but their importance for battling SARS-CoV-2, the virus that causes COVID-19, has been unclear. Now, two studies reveal infected people harbor T cells that target the virus—and may help them recover. Both studies also found some people never infected with SARS-CoV-2 have these cellular defenses, most likely because they were previously infected with other coronaviruses.
