Beijing has virtually walled itself off to outsiders with drastic measures to protect China's seat of power against the threat of a second wave of coronavirus infections from other regions. After largely getting the outbreak under control, China has banned foreigners from entering the country as authorities fret over an increase in cases imported from abroad - though most have been Chinese citizens.
Wuhan doctor Ai Fen, who expressed early concerns about the coronavirus to the media, has disappeared and is believed detained by Chinese authorities. Fen, the head of the emergency at Wuhan Central Hospital, was given a warning after she disseminated information about the coronavirus to several other doctors.
A Chinese doctor who was among the first to warn publicly about the new coronavirus outbreak - and was reprimanded by authorities for “spreading rumours” - died of the infection early on Friday, his hospital announced.
