KUCHING, Sept 6: The Covid-19 Delta variant has higher chances of being transmitted by infected individuals through breathing, singing, and even talking, said State Disaster Management Committee (SDMC) advisor Dato Sri Dr Sim Kui Hian.

According to Dr Sim, even breathing quietly carries a risk of getting infected with the virus, while conducting heavy activities which require breathing through the mouth has seven times’ higher chance of infection.

“This includes talking normally (8 times), singing normally or talking loudly (11 times) and singing loudly (90 times).


“Million of virus particles can be released into the air by an infected person when he or she breathes, sings or even talks,” said Dr Sim in a social media post yesterday (Sept 5).

Dr Sim, who is also Minister for Local Government and Housing, pointed out that virus transmission can be prevented by double-face masking (a three-layered face mask with a fabric outer layer and face shield).

As such, he reminded the public to not take off their facemasks in the workplace, public places (unless alone), as well as at home when there is a visitor or relative not from the same household around.

“When a person takes off his or her mask, they either release the virus into the air or breathe in virus laden air,” he added. — DayakDaily
