Vermont has two new clusters of coronavirus cases, health department officials reported Wednesday: One among a family in Windham, another at a worksite in Fair Haven.

There were 20 new cases of the virus reported in Vermont on Wednesday morning, the highest number since June 3, when an outbreak peaked in Winooski.

Health Commissioner Mark Levine would not confirm the size of the Windham County cluster, saying it was limited to a single family of fewer than 10 people. The worksite in Rutland County has had 12 cases so far, he said at a press conference.

The state is currently testing some people in both areas, he said, and there will be opportunities for testing in the community later this week.

Levine said defining a “cluster” is complicated, but that it generally refers to a series of closely connected cases within a single area.

Pressed about the nature of the worksite outbreak, Levine declined to mention the name or industry of the employer, saying it could reveal private health information about the workers.

“Conveying that information could be identifying and injurious to the population,” he said, adding that the workplace most likely did not have public contact, like people shopping.

The new information about the clusters comes as the outbreak in Winooski winds down. Levine said 114 people in total have tested positive in the area, with only four new cases since June 21.

As previously reported, the outbreak in Winooski occurred mostly among younger Vermonters and fewer than half reported symptoms.

Levine did not release demographic details about the new outbreaks, but he mentioned that across the US, an increasing number of young people are testing positive for the virus.

In Florida, for example, more people ages 18-35 are testing positive than ever as virus cases reach new highs.

Vermont’s latest outbreaks have seen a shift from the early days of the pandemic, when the most devastating outbreaks occurred in facilities, like long-term care homes and prisons.

Instead, Winooski and Windham County have seen cases spread among social networks, while Fair Haven’s cluster occurred at a workplace.
