There's one thing that distinguishes the nursing homes in New York that have reported patient deaths from COVID-19. According to an NPR analysis, they are far more likely to be made up of people of color.

NPR looked at 78 nursing homes in New York in which six or more residents have died of COVID-19. In one facility, 55 people have died as of April 20. Ten others report 30 or more deaths.

One month ago today, President Trump declared a national emergency.

In a Rose Garden address, flanked by leaders from giant retailers and medical testing companies, he promised a mobilization of public and private resources to attack the coronavirus.

"We've been working very hard on this. We've made tremendous progress," Trump said. "When you compare what we've done to other areas of the world, it's pretty incredible."

But few of the promises made that day have come to pass.

On Feb. 29, the U.S. surgeon general Dr. Jerome Adams tweeted that masks do not offer any benefit to the average citizen.

A few months ago, it may have seemed silly to wear a face mask during a trip to the grocery store. And in fact, the mainline public health message in the U.S. from the Centers for Disease Control and Prevention has been that most people don't need to wear masks.

But as cases of the coronavirus have skyrocketed, there's new thinking about the benefits that masks could offer in slowing the spread. The CDC says it is now reviewing its policy and may be considering a recommendation to encourage broader use.

On Weibo, the Chinese version of Twitter, user 一只猫叫鱼Yu kept a public diary of her lockdown experience in Wuhan, China. On day 29, she described losing track of time. "I watch the days go by one after another," she wrote. "I don't know how long days like this are going to last."

With jittery shoppers flocking to supermarkets to stock up on supplies for the coronavirus outbreak, some of the country's largest grocery chains are announcing measures to enhance sanitation and maintain supplies.

Across the U.S., hand sanitizer, toilet paper, sanitation wipes and canned goods have been flying off shelves as the number of confirmed coronavirus cases continues to climb.

China says it has launched an investigation into "issues" related to the death on Friday of a doctor whose early efforts to alert his colleagues to the dangers of a new coronavirus were quashed by authorities.

Meanwhile, President Trump spoke with China's leader Xi Jinping to discuss the coronavirus epidemic, which has rapidly gone global since it began in China in December.

Dr. Li Wenliang, an ophthalmologist working in Wuhan, the Chinese city where the epidemic originated, died on Friday local time, weeks after he was hospitalized and treated for a coronavirus infection.

A Chinese doctor who was among the first to blow the whistle on the new coronavirus has died from the disease, the hospital treating him said on social media early Friday local time.

Li Wenliang, 34, an ophthalmologist based in Wuhan, was reprimanded in early January by local police authorities for "publishing falsehoods" after he mentioned in a WeChat group seven cases of a virus similar to SARS from a seafood market.
