Two hospitals in Manchester, New Hampshire, are investigating clusters of patients and staff who have tested positive for the coronavirus.
Two asymptomatic patients from the same unit at Catholic Medical Center were discovered to be positive after being tested for placement at long-term care facilities. A staff member on that unit also tested positive, hospital officials said.
Catholic Medical Center tested all patients on that unit and more than 600 employees between May 20 and May 26. Seven patients and staff came back positive so far.
At Elliot Hospital, five patients on the geriatric psychiatric unit have tested positive. The hospital is currently testing the remaining patients and all staff on the unit.
Both hospitals are conducting contact tracing to determine the source and scope of exposure, which appears to have occurred via asymptomatic spread in both cases.
