broad lockdowns do not appear to make much difference to the spread of the virus in nursing homes. Long-term care facilities are uniquely vulnerable to the coronavirus because their patients are both medically fragile and live close together. Fewer than 0.5 percent of Americans live in nursing homes – fewer than 1 in 200 people. But in both the United States and Europe, nursing home residents have accounted for 40 to 50 percent of all Covid deaths, well over 100,000 in all.
