Editorial | No need to be selfish in choice of coronavirus masks
- The type of mask worn at a Hong Kong quarantine hotel has been blamed for a cross-infection, underlining the need to wear face coverings that are effective and safe
Wearing a mask has long been recognised as pivotal to Hong Kong’s success in keeping Covid-19 largely under control. But with the pandemic dragging on for nearly two years, the practice may have been taken for granted by some.
The use of a mask of a “selfish” design, which filters air breathed in, but not out, by a guest has been blamed for a recent cross infection at a quarantine hotel. The case underlines the need for renewed awareness of the proper use of masks during a prolonged battle.
The 36-year-old man from South Africa wearing the reusable mask was suspected to have infected another guest in an opposite room at the Regal Airport Hotel. Leading microbiologist Professor Yuen Kwok-yung described the type of mask as “selfish”.
Thankfully, it did not result in a wider outbreak, but guests in 12 other rooms on the same floor had their isolation period extended for another 14 days as a precaution.

Hong Kong microbiologist blames 'selfish' mask for Covid-19 cross infection at quarantine hotel
