SHERMAN — There have been five new cases of COVID-19 in town in the last nine days, First Selectman Don Lowe announced Thursday afternoon.

Lowe said the fifth case was reported Thursday morning and he is urging residents to remain vigilant about health protocols, including wearing face coverings, practicing social distancing and cleaning hands and surfaces.

There have been 20 confirmed coronavirus cases in Sherman since March, according to the state Department of Public Health.

Sherman is currently classified as “orange” in the state health department’s weekly, color-coded COVID-19 alert system, one step below red. The system is based on average daily rates of new COVID-19 cases during the past two weeks. Red, the most severe, means those towns are seeing more than 15 cases on average per 100,000 people.

Gov. Ned Lamont has urged towns labled red to scale back their business reopenings and to consider distance learning, but invited those considered orange (10-14 cases per 100,000 people) to also scale back.
