MILAN/SEOUL (Reuters) - In Italy, millions are locked down and more than 800 people have died from the coronavirus. In South Korea, hit by the disease at about the same time, only a few thousand are quarantined and 67 people have died. As the virus courses through the world, the story of two outbreaks illustrates a coming problem for countries now grappling with an explosion in cases.
Epidemiologists say it is not possible to compare the numbers directly. But some say the dramatically different outcomes point to an important insight: Aggressive and sustained testing is a powerful tool for fighting the virus.
