A good place to start to reduce the number of infections would be to work out a proper test. With PCR tests you can modify the number of cycles to fit your goals, from "serious pandemic" to "we are almost case free" within days. Also it seems like these tests test positive for people who have been infected months ago, so it's more than likely to pile up the numbers of cases even though most of those aren't really active anymore.
