The coronavirus has now hit the leader of the free world, with President Trump announcing early Friday that he has tested positive. Given Trump’s continued insistence on holding large public events and the fact that those events and his private meetings rarely include masks, there are now questions about just how much the virus might have spread among his inner circle and people with whom he has come into contact.

“Given the nature of the interactions, there are a potentially large number of people who are going to meet the exposure definition,” said Lisa Maragakis, an epidemiologist at Johns Hopkins University. She said that large number is “just based upon the public events that we know of, and I’m sure there are many private meetings that need to be considered, too.”

Below is the most recent list of who we know has tested positive or negative, and what their proximity to the president and others was.

(It’s important to emphasize, though, that one negative test doesn’t mean one hasn’t contracted the virus. Several White House aides have repeatedly tested negative before testing positive. As Maragakis noted, the incubation period is generally two to 14 days, but for most people it is around four or five days. Anyone who is exposed should quarantine for 14 days.)
