Covid in Daily life

My son and DIL work at an assisted living place. A little over two weeks ago they had two staff members test positive. This past Sunday, just when they thought things were easing up, another staff member tested positive and today they found out that a resident who is in the memory care side of the facility tested positive. So far she has no symptoms . The workers who tested positive were not caregivers but worked in the kitchen. To say they are stressed is an understatement.
