No clue what it is with Kowloon Bay - same drainage pipe design as Amoy Gardens.
All residents living in a Kowloon Bay housing block facing the same direction will be moved to quarantine centres after a government advisor and University of Hong Kong microbiologist, Yuen Kwok-yung, said the Covid-19 virus might have spread through the building's sewage pipes.https://news.rthk.hk/rthk/en/compone...9-20201210.htm"We know that all the cases are in the units D of Block 6, and as a result there is a good reason for us to suspect a structural problem, especially those related to the sewage system," Yuen told reporters after inspecting the building on Thursday.
"All the floors' drains, from either the bathroom, or the toilet, or the kitchen all drain into the sewage pipe, and [in] some of them we may not be able to see there's a U-trap," he said, referring to the pipe design that wards off germs and viruses.
Yuen said the drainage pipes were designed similarly as those in Amoy Gardens, which was at the centre of the Sars outbreak in 2003.
