The coronavirus pandemic has thrust many Americans into the role of caring for an older or disabled loved one for the first time, a new poll finds. And caregivers on the whole say they’re encountering unexpected risks and demands as a result of the virus, requiring greater time and effort. Still, they’re more worried about the relatives and friends they are helping than about themselves. The Associated Press-NORC Center for Public Affairs Research poll finds that 17% of Americans say they are providing ongoing caregiving, part of an informal volunteer corps. About 1 in 10 caregivers has begun since the virus outbreak, and about half of those say they are providing care specifically because of the pandemic.
