VERMONT — Officials in Vermont say the outbreak of COVID-19 that began in the city of Winooski on Memorial Day has grown to 62 cases, including nine in the adjoining city of Burlington and five in other communities.

Health Commissioner Dr. Mark Levine said Monday that 38 are adults and 24 are children with a median age of 21. There have been no reports of hospitalizations or deaths and only one in five of the infected individuals showed any symptoms.

Officials say the outbreak is confined to “one social network of families,” but they have been reluctant to provide more details, citing confidentiality concerns.

State Epidemiologist Patsy Kelso said contact tracers have identified shared activities that could have led to the outbreak and officials believe there has been spread within households as well.

“We think this is a pretty-well contained situation or outbreak and while the case numbers may go up because there may have been exposures in the recent days even, we don’t think this is something that we will see pop up all over the state,” Kelso said.
