Amid the evolving COVID-19 situation, the Singapore government is no longer discouraging people from wearing masks when they are well.
The new evidence suggests that infected people may be able to spread the virus to others for two to three days before becoming ill, says Associate Professor Hsu Li Yang, Programme Leader (Infectious Diseases).
He said, “By wearing a mask — even a cloth mask — these pre- or asymptomatic persons may be a little less likely to spread the virus to others.”
When removing their masks, people should be careful not to touch their eyes, nose and mouth, and should wash their hands immediately after. Reusable masks should be properly washed and dried after each use.
Assoc Prof Hsu noted that while masks provide an additional layer of protection, practising social distancing and maintaining good personal hygiene are more important in preventing the spread of the virus.
Due to a global shortage of surgical masks, Dean, Professor Teo Yik Ying urged the public to reserve the supplies for front-line healthcare workers, who are at higher risk and in most need of them.
