MILAN/SEOUL (Reuters) - In Italy, millions are locked down and more than 1,000 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.
It's impractical to test every potential patient, but unless the authorities can find a way to see how widespread infection is, their best answer is lockdown.
