Yesterday, Centre for Health Protection officials locked down a Sheung Wan residence tower for mandatory testing, even though the person who has tested positive for Covid19 has a high antibody rate and returned from the United States last night.
This would only suggest that he acquired the infection in the US, say experts.
It seems that the catalyst for such urgency in testing is the knowledge that he carries the L452R variant, which is more contagious than other variants.
The man works at a local company and was staying in the residence from June 27 to July 4. He left for the United States on July 4 and returned on July 19.
Even though he hasn't been in his building for two weeks, and even though nobody in his building has tested positive for the virus, they are locking down his building and testing everyone in the building.
Anyone who has spent more than two hours in the building from June 27 to July 19 is mandated to undergo testing.
