China’s Ministry of Health and the World Health Organization (WHO) experts held a press conference in Beijing on February 24. At the conference, Bruce Aylward, Assistant Director General of WHO, led a group of experts to visit China to check on the coronavirus situation there. He said that he had been to Wuhan but did not go to the “dirty areas” in the Wuhan hospitals. He then rushed to catch the plane to fly out of China without quarantining himself for 14 days (after returning from Wuhan).
News reporters suspected that “dirty” was a technical term referring to infectious areas.
