Who bought all the toilet paper? Study suggests who was most likely to stockpile during COVID-19

In mid-March, as coronavirus cases started their sharp climb in the United States, many Americans appeared to have one thing in mind before hunkering down: Buy toilet paper. Lots of it.

But not everyone grabbed every roll in sight, and research published Friday in the journal Plos One offers insights into why some people scrambled for toilet paper while others held back.

The study looked at whether different personality traits were associated with toilet paper hoarding, and found stockpilers tended to be more anxious and fearful about the coming health threat compared with those who didn’t load up on the product.

The Department of Transportation plans to distribute nearly 100 million masks for passenger use, the department announced in a news release Friday.

Few N95 masks, reused gowns: Dire PPE shortages reveal COVID-19's racial divide

Amy Arlund, an intensive care unit nurse in California, starts every overnight shift hoping her supervisors will give her a fresh N95 respirator.

“You are asked to reuse them for weeks on end,” Arlund, 45, told NBC News. “You have to justify to your manager repeatedly why you need a new one.”

Nearly 100 days after the World Health Organization declared the coronavirus outbreak a pandemic, health care workers across the country are still facing major shortages of personal protective equipment, or PPE, including crucial equipment such as masks, gowns, gloves and N95 respirators. Amid an alarming rise in coronavirus cases across the United States, the situation is especially dire at hospitals serving communities of color or patients on Medicaid, NBC News has found.

"The issue of PPE for health workers has not gone away," Dr. Mike Ryan, head of the WHO's Health Emergencies Program, said Wednesday at a news briefing.

How did 140 people avoid coronavirus at salon where 2 stylists tested positive?

Coronavirus contact tracing apps were tech's chance to step up. They haven't happened.

At a briefing this week, New Jersey Gov. Phil Murphy touted his state's efforts to trace the spread of the coronavirus, outlining plans to hire 1,600 contact tracers who will call people who may have been exposed to the coronavirus.

Not part of his plan: a smartphone app to help with contact tracing.

"The state of New Jersey is neither pursuing nor promoting exposure notification or digital alerting technology, at least at this time," Murphy said.

New Jersey isn't alone. States that had committed to using contact tracing apps or expressed interest are now backing away from those claims. The few states that have rolled them out have seen only tepid responses. And there are no indications of any momentum for the apps at a national level.

Beijing elementary students' return to school delayed after new coronavirus cases found

The return to school of Beijing students in years 1, 2 and 3 has been delayed after two new coronavirus infections were diagnosed in China’s capital. The students were scheduled to return to school this coming Monday.

Students who already returned to class will remain in school, the government said.

The two coronavirus cases, which are believed to have been transmitted in China rather than from abroad, were isolated and treated in Beijing coronavirus hospitals. On Thursday, China reported 11 newly confirmed cases across the country, but they all came from outside the country.
