Was talking to my brother today. He has lived in Singapore for many years. Currently, he said, they are having just about zero cases of the virus in the community. They have a few (as in, under 10) cases in immigrant worker dormitories. They are not opening everything up yet. Schools have been open since July, but all pupils must wear a mask all the time. In face, everyone must wear a mask outside their own home, even out in the open air. If you are caught anywhere outside your home without a mask, it's a $300 on the spot fine, no exceptions, no extenuating circumstances, no faffing around with court appearances/defence arguments etc. Bars that sell food, Cafes and restaurants have reopened with very strict measures in place. Numbers are limited, there can be no interaction at all with diners at another table. You must wear your mask unless you are actually eating/drinking at that moment. And once you are finished your meal, you must leave immediately. Any premises found in breach of regulations (even if they have been trying to enforce them with customers) is automatically shut down immediately. No travel into or out of the country, except ESSENTIAL business travel, and you have to provide proof that the travel is definitely essential, and is definitely for business and nothing else.
Of course, Singapore has dealt with epidemics and outbreaks of infectious disease several times before. They kind of know the drill. And the population will go with the regulations, particularly mask wearing, because they know that it works if everyone complies.
Oh, he also said that everyone has a qrl(?) code on their phone, which you must scan going into any shop, bus, train, cafe, anywhere in fact. Which means that if a case arises anywhere, they have the contact tracing down immediately. It all sounds unsurprisingly efficient!
