Singapore has contact tracing teams, who identify all the contacts of an infected person and ring them up. Often these people have early symptoms and we’ll arrange for them to be picked up and tested. Singapore is very liberal with our testing. Less than 1 per cent of our tests are positive, so that reflects just how many tests we are doing. If people don’t have symptoms, they’re put in home quarantine. And home quarantine is very strict. A couple times a day, you’ll get an SMS and you have to click on a link that will show where your phone is. In case you cheat and leave your phone at home with someone else, the government has people knocking on doors now and then. The penalties are pretty harsh.
