The coronavirus alert was sent out to members of the press pool on Monday by WHCA president Jon Karl, who revealed only that the individual was at the White House four times in the past two weeks, perhaps in an effort to allow journalists who skipped those days to breathe a little easier.

Karl urged journalists to “review public health guidance, consult their medical professionals, and take the appropriate next steps.” Members of the pool were advised to stay home if they felt ill and to inform the group if they, too, tested positive for the virus.

US President Donald Trump appeared to confirm that a corps member has fallen ill with the Covid-19, extending his "best wishes" to the coronavirus-stricken journalist during his daily briefing on Monday.

“I see we have fewer people because of the virus problem,” Trump said just after he took to the podium in the briefing room.

The WHCA followed up its initial letter with a revised seating chart implementing stricter “social distancing,” explaining that the layout had been drawn up “in consultation with news outlets and the White House physicians’ office.” Security measures in place since last week already require journalists to have their temperatures taken before entering the briefing room and to avoid large “press scrums” around lawmakers. While the Capitol is closed to visitors because of the coronavirus, media are still permitted, along with legislators and their staff, and no temperature checks are currently in effect. 

Some on social media pointed out that Trump had just warned reporters days ago that they were sitting too close together and called to cut back on the number of journalists at briefings, fearing infection himself.

Others began to speculate on who the infected person might be – “that OANN is chinese food racist chick”? Jim Acosta?
