Research results show that physical distancing can only be relaxed in ratio to the rate of vaccination in the city’s population until herd immunity is achieved. A CUHK team developed a social contact index (SCI) which quantifies the effect of distancing and vaccination combined, to bridge gaps between intervention measures and disease transmission.

A university research team has found that lower levels of “good” bacteria and higher levels of “bad” bacteria in the gut of people with COVID-19 has made it harder for them to fight off the virus. The team has since developed a probiotic supplement based on this research to enhance the “good” bacteria thereby offering hope to boosting immunity against the virus in everyone who could be at risk.

Stool, found to be a “shed” for the coronavirus. According to the latest study, the coronavirus was found in faeces samples from 14 COVID-19 patients, regardless of the severity of their condition. 3 of them still had virus even though their respiratory secretions were cleared of the virus. Researchers suggest faeces test as an alternative screening.
