Politico, the Washington Post, and the Daily Beast have asked reporters who covered CPAC to self-quarantine and work remotely due to concerns that they may have been exposed to the novel coronavirus. Both the Post and Politico say they’ve taken measures to clean and sanitize public areas. The Post has asked employees who were at CPAC to self-quarantine for seven days. All newsrooms tell Washingtonian they’ve taken such measures out of an abundance of caution.

“We understand that this news may be jarring, but it’s important to recognize that this was a large conference and that the risk of transmission for employees who were not in close contact with the infected individual is extraordinarily low,” Politico’s memo says. The Post has already canceled nonessential travel for employees. It has also canceled all WP Live events for March and has canceled office tours.
