Testing half the population weekly with inexpensive, rapid COVID-19 tests would drive the virus toward elimination within weeks, even if the tests are less sensitive than gold-standard. This could lead to “personalized stay-at-home orders” without shutting down restaurants, bars, retail and schools.
The problem with self isolation/stay at home orders, is that people don’t/won’t obey self isolation/stay at home orders. Especially if they’re one of those people who either have mild or no symptoms and everything is open, they will just carry on with their normal lives. People are far too self centered/selfish.
