"Flattening the curve," the goal behind "lockdowns" and similar stay-at-home policies enacted in many countries, has enabled health care services to address what was feared to become an even larger number of patients made seriously ill by the coronavirus.
Stay-at-home measures slowed case growth and bought time to plan, reducing eventual pressures on staff, capacity and supplies of drugs and equipment. "A large number of people becoming sick over the course of a few days could overwhelm a hospital or care facility," Dr. Lisa Maragakis, a Johns Hopkins medicine professor, says.
Governments and private-sector forecasters watch ongoing case counts carefully to be sure that the curve stays below the zone that would renew pressure on health care systems.
