World Health Organization’s mission to trace the origins of Covid-19 got off to a rocky start on Thursday, with two members of the 15-person delegation denied entry to China after failing to clear health-screening procedures.The two experts were stopped from boarding a plane to the city of Wuhan after testing positive for Covid-19 antibodies in blood-based serology tests during transit in Singapore, even though they tested negative for Covid-19 in swab tests, Dow Jones reported, citing unidentified people familiar with the matter.
The WHO later confirmed that two scientists were stuck in the city-state as video showed the others arriving in Wuhan around noon.Two scientists are still in #Singapore completing tests for #COVID19.
