China bars two members of WHO coronavirus mission as depleted team reaches Wuhan – The Washington Post

two researchers were kept in Singapore, where they were transiting, and prevented from continuing to Wuhan after failing to clear health checks. China requires all airline passengers to present negative antibody tests before being able to travel to the country.

The pair had tested positive for coronavirus antibodies in their home countries before leaving. All members of the team, tested before leaving and once again in Singapore, tested negative for the virus.
