The expert warns against a specific type of masks

A microbiologist at the University of Hong Kong made this statement after an inspection of a hotel where quarantines are taking place and where one of the guests most likely infected a person in an adjoining room with coronavirus. The authorities are trying to find out how this happened.

Bad mask?

The monitoring recordings show that the man who was previously diagnosed with the infection usually used a mask with a filter and a valve when he took meals at the threshold of the room and left garbage there. According to Yuen, this increased the risk of airborne contamination of a neighbor.

– This kind of face mask is selfish. They filter the air as you inhale, but when the air is exhaled through the valve, it is not filtered, which is not good, Yuen said. He recommended the use of surgical masks.

An infected man sometimes showed up at the open door, even without a mask, but the South China Morning Post noted, which reported on Tuesday.

They were fully vaccinated

Both infected were fully vaccinated against COVID-19. Due to infection in the hotel, 12 other people staying on the same floor have to extend the quarantine for a further 14 days.

The Hong Kong authorities, like the PRC central government, adhere to the “zero covid” principle and maintain strict entry restrictions, including a 21-day quarantine obligation for most visitors. In recent weeks, they have tightened the rules further, trying to convince Beijing to facilitate travel between Hong Kong and mainland China.
