The president's missteps after being exposed to the coronavirus have amplified the risks of spreading it to others and undermined the recommendations of public health officials.

Political figures who had contact with the president in the past week are being tested — and reporting negative results. Doctors sound a note of caution about what those results indicate.

The Centers for Disease Control and Prevention last week said that COVID-19 spreads "most commonly" through air — then took it back. Is this something I should be worried about?

NPR has obtained draft documents that indicate the federal government is planning to cut off Medicare funding to hospitals that don't comply with a request to supply daily COVID-19 data.

Draft documents obtained by NPR show that the federal government is preparing to enforce new data reporting requirements, threatening to withhold vital Medicare funding from noncompliant hospitals.

Advisers to the Centers for Disease Control and Prevention discussed on Tuesday who will get the first doses of a coronavirus vaccine when it is available.

A CDC advisory committee is debating this issue Tuesday. Half of U.S. adults could be considered high priority, yet the initial supply is likely to be only enough for 3% to 5% of the population.

When a COVID-19 vaccine is approved, who gets first dibs? Bioethicists say the focus should be on saving the lives of people most at risk. Frontline health workers go first, but the rest is trickier.

The Centers for Disease Control and Prevention updated its guidelines Friday to say the coronavirus can spread via tiny aerosol particles. But on Monday, the agency abruptly pulled the new guidance.

Political interference on COVID-19 guidelines at the CDC, a DHHS spokesman on leave after attacking scientists on facebook live, and the President continues to contradict the science of the pandemic.

Trump says a COVID-19 vaccine could be ready by the end of 2020. At the same time, the top communications official at Health and Human Services is going on leave after comments he made on Facebook.

Michael Caputo is taking a two-month leave of absence after a social media outburst alleging an unfounded "deep state" conspiracy involving government scientists.

Revelations in Rage lead global health specialists to charge that Trump is scapegoating the World Health Organization.

There's increasing evidence that the coronavirus can linger and spread through the air in crowded indoor rooms. Researchers say infectious clouds can be dispersed with fresh air.

An epidemiologist and a grad school graduate who'd gone to see family reflect on how tough it was to be cut off — and what they learned from their months-long quarantine.

Scientists say it's increasingly clear that airborne virus particles help the coronavirus superspread. Here's what they recommend to reduce the risks.

That's the word that one disease researcher uses to describe COVID-19. And now scientists are discovering the reasons that this virus is readily transmitted at "superspreader events."

The coronavirus appears to transmit unevenly: A few people can infect many, while others don't pass the virus on at all. Researchers are working to understand the factors that drive superspreading.

Dr. Deborah Birx says the Centers for Disease Control and Prevention is creating a new way to track COVID-19 hospitalizations a month after such data collection was moved outside the agency.

The Trump administration had promised complete, transparent information on the coronavirus and hospital capacity. Instead, the new system has produced erratic updates and confusing numbers.
