There is no need to suspend lessons despite the nine local virus cases reported yesterday, top microbiologist Yuen Kwok-yung said on a radio program this morning.
The University of Hong Kong professor believes that the recent outbreak is due to the relaxation of social distancing measures since Father’s Day around two weeks ago.
He emphasized that an “invisible transmission chain” had been in the city all along but the government had never increased testing. As a result, whenever local transmission cases arise, the government will have to tighten its measures again.
Yuen praised the Education Bureau’s anti-epidemic guidelines and said the annual book fair can go ahead as planned, as long as appropriate anti-epidemic measures are in place.
He added that karaoke lounges and restaurants are high-risk venues, as each milliliter of a patient’s saliva can contain 100 million to 1 billion virus particles. If a waiter or kitchen staffer comes in contact with the saliva, they can easily transmit the virus.
