In New York City, emergency hospital beds are multiplying — inside tents set up in Central Park, on a hospital ship docked on Manhattan's West Side and in the Javits Convention Center, which now houses about 1,000 beds.

Under lockdown, well-off Indians isolate indoors, work from home and get groceries delivered.

But outside their windows, it's a different story: Poor laborers amass in the streets, hungry and homeless.

In a video posted on Twitter, a woman calls down to a crowd of people gathering below her window. They yell back up to her, desperate: "There are 400 of us here without food. We need help. There are lots of children."

The Central Asian country of Turkmenistan claims it has no coronavirus cases.

With tests scarce, epidemiologists are looking at hospitalizations as an indicator of how the novel coronavirus is spreading. But in some of the areas of the country worst-hit by COVID-19, states and counties aren't releasing that data.

The result is an incomplete picture of where the pandemic is surging, even in hotspots such as Washington and California.

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.
