SALT LAKE CITY (AP) — For millions of disabled people and their families, the coronavirus crisis has piled on new difficulties and ramped up those that already existed. Needed disinfectants and protective equipment are in short supply, and technological lifelines to the outside world aren’t accessible to everyone. Many are immunocompromised and therefore more vulnerable to the infection, but concerned about coronavirus-era hospital guidelines. As several states move toward reopening businesses shuttered by the virus, they’re staying behind closed doors, worried that more interaction could lead to a wave of new infections. Many say it’s taking an emotional toll on them and their families.
