For the past month or so, Leikish Nails has engaged in an elaborate ritual the minute she gets home from her shift at Touchpoints at Manchester, a skilled nursing facility that has seen four deaths and more than two dozen illnesses caused by COVID-19. She kicks her shoes off before she walks in, sprays them and leaves them on the deck before disrobing in potentially full view of the neighbors. Her clothes immediately go in the washing machine seconds before she jumps in the shower. “I don’t hug my kids as much as I used to,” the 38-year-old Willimantic resident said. “I’m afraid to hug my kids,” she said while crying during a recent phone call.
