Earlier this week, the government announced an end to the mask mandate. But some people decided to continue wearing masks in public.

In an interview following a radio segment, Dr. Hung said mask-wearing in public could prevent Covid and other upper respiratory tract infections among high-risk individuals.

Individuals should make their own decisions on whether to wear face coverings, but those with the greatest vulnerability should continue to do so, said Hung.

Hung told reporters that if an individual has chronic illnesses or is over 65, they should wear masks, especially in crowded places, such as public transportation.

Healthcare workers should continue to wear masks in hospitals, clinics, and elderly homes to prevent Covid, and other respiratory virus infections, especially influenza, and cross-infection, Hung added.

For secondary school students, taking a rapid antigen test every day to return to class won't be necessary, but younger students will still have to perform the test until March 15.

Now that masks aren't required, the daily testing rule could also be scrapped, Hung said.

As for Covid vaccinations in the future, the medical expert recommended booster shots before winter each year for the general public and every six months for elderly and chronically ill people.
