The COVID-19 pandemic has challenged health systems and public health authorities worldwide. When you have a rapidly spreading virus with a high transmission rate, you have to investigate all possible infection risks.
Michael Gormley writes in The Conversation that one area of risk that is yet to receive any attention is big buildings such as tower blocks or hospitals. While direct person-to-person transmission is still the most common means of acquiring the illness, our research suggests that occupants in tall buildings could become infected if defects occur in the plumbing system. It’s important for people to be aware of this and take steps to keep themselves safe.
His group’s work at the Institute for Sustainable Building Design at Heriot-Watt University stems from an outbreak of the SARS virus in 2003 at an apartment block in Hong Kong, known as Amoy Gardens. In a building complex ranging from 33 to 41 storeys with some 19,000 residents, there were more than 300 confirmed cases and 42 deaths – around one-sixth of all SARS infections and fatalities on the island as a whole.
