In April, Rhonda Eigabroadt, 53, showed up at the ER at MidState Medical Center in Meriden, struggling to breathe. Doctors did not expect her to survive the night, she recalled. Ten days earlier, she had tested positive for COVID-19 and was recovering at home in Bristol before taking a turn for the worse. An occupational therapist at the Litchfield Woods Health Care Center in Torrington, she, along with scores of staff and residents, had contracted the virus during an outbreak. Eigabroadt beat the odds, though.
