RT [@VincentRK](https://twitter.com/VincentRK/status/1250875051659968513) Singapore should be a warning to us. They had COVID under excellent control. Now it’s out of control: 728 new cases yesterday. When we relax social distancing measures prematurely we risk a second wave. Places where groups of people work/live close to each other are at high risk. https://t.co/vMnEfNSU0Y
