China: man tests positive after 3 weeks in quarantine and 9 negative Covid tests
A man who completed 21 days of mandatory quarantine upon returning to China from overseas has been identified as the likely source of a new Covid outbreak. The man underwent 14 days of compulsory hotel quarantine, another 7 days in centralized quarantine and then a further week of health monitoring. He had tested negative for the virus nine times during 21 days of quarantine, before testing positive 37 days after entering China.
Putian’s locally-transmitted epidemic mainly has two chains of transmission – the one relating to Putou Primary School and one relating to Xiesheng shoe-making factory. The total infections from the school increased to at least 15 and at least 10 other infections from the Xiesheng shoe-making factory as of press time.
Preliminary studies suggest the outbreak may be traced to father of a student at the school who recently returned to Putian from Singapore. The person surnamed Lin tested positive on September 10, 38 days after returning from Singapore on August 4, during which he took nine nucleic acid and serologic tests, which were all negative.
