The minute you leave your room, or you leave your house, you have to wear a mask when you go out.”

Children below the age of two will not need to wear a mask based on medical experts’ recommendations on child safety, he said.
As for adults, only those who are engaging in strenuous exercises like running and jogging do not have to wear a mask, but they will have to put it on once they stop exercising.
Mr Wong also reiterated the need for them to maintain a safe distance from others when they are exercising.
“Please do not use this mask-wearing requirement now to say ‘ok, I can go out’," said Mr Wong.
“You should not go out as much as possible. Just stay at home. Do all the right things - practice good hand hygiene and stay at home as much as possible,” he added.
“But in the rare occasion that you do need to go out for purchase of your groceries or purchase of essentials, then it's only at that time that you wear a mask.”
“We are very happy that many Singaporeans and residents are cooperating and doing their part, and complying with these measures,” said Mr Wong, noting that movement across the island has reduced significantly.
With safe distancing ambassadors and enforcement officers “hard at work on the ground”, hotspots like wet markets, hawker centres and parks “are generally now under control”, he said.
“Most people are doing the right thing. There are a few who are not and they will be dealt with.”
Acknowledging that some people are finding it “hard to adjust” to the circuit breaker measures and are “suffering from cabin fever”, Mr Wong said the Government has had to reject many appeals for activities.
“We cannot let up at this stage. These are still early days and we have at least another three more weeks to go. So we have to double down on our efforts and just stay at home.”
About 20 per cent of the workforce comprises essential workers and continue to travel to their workplaces, Mr Wong noted. But the list of companies classified as essential services will be tightened further to reduce the number of people commuting to work.
Noting that on top of wearing masks, Health Minister Gan Kim Yong said observing personal hygiene “is a very critical factor in disrupting the transmission chain”.
“This is particularly important during this period of enhanced safe distancing. And that is why we have also enhanced our advisory on the masks, and now making it mandatory when you go out, because we want to do everything we can to reduce the risk of transmission, so as to keep our keep our number of cases to as low as possible. And this is in line with our strategy of this enhanced safe distancing approach over the next few weeks.”
