A Massachusetts mother has identified her newborn daughter as the possible case of Powassan virus that is under investigation by health officials on Martha's Vineyard. Health officials did not disclose where on the island the patient lives,

The potential case comes during one of the worst tick seasons in New England in years, with a surge of tick-borne diseases and tick exposures. Only one case of Powassan virus has been recorded on Martha’s Vineyard in the past 20 years, officials said. So far this year, three cases have been confirmed in Massachusetts.
