A region of Italy that took earlier and more aggressive measures to fight the coronavirus is now seeing fewer cases.
One region, Veneto, tested everybody, even those with no symptoms, and the other region, Lombardy, only tested those with symptoms. The result is that Veneto is seeing a decrease in the spread of the virus and therefore less deaths, while Lombardy is seeing an increase in both the spread and deaths.
What countries need to do is test, test, test.
