WEST YARMOUTH - An outbreak of COVID-19 cases at a West Yarmouth nursing home is spurring concerns about the resurgence of the coronavirus during the busy summer tourist season. More than 10 employees and residents have tested positive for COVID-19 at Maplewood at Mayflower Place in recent days, Bruce Murphy, health director for the town of Yarmouth, said Friday. Most of the cases have occurred in vaccinated individuals who have not fallen seriously ill, Murphy said. “Right now, it’s just been a mild illness.” The nursing home cases coincide with a spate of positive, but also mild, cases of coronavirus among people who were tested recently at the Outer Cape Health Services office in Provincetown.
