`If this thing boomerangs': Second wave of infections feared

As Europe and the U.S. loosen their lockdowns against the coronavirus, health experts are expressing growing dread over what they say is an all-but-certain second wave of deaths and infections that could force governments to clamp back down. “We’re risking a backslide that will be intolerable,” said Dr. Ian Lipkin of Columbia University’s Center for Infection and Immunity. Elsewhere around the world, German authorities began drawing up plans in case of a resurgence of the virus. Experts in Italy urged intensified efforts to identify new victims and trace their contacts. And France, which hasn’t yet eased its lockdown, has already worked up a “reconfinement plan” in the event of a new wave.
