MIDDLETOWN — Middlesex County passed the threshold established by the Centers for Disease Control and Prevention for “substantial” COVID-19 spread Friday, leaving Litchfield County as the last one in Connecticut at a lower level.

In the counties with substantial spread, more than 50 cases per 100,000 people over a seven-day period were reported, according to the CDC.

According to data posted by the CDC Saturday, 85 cases over the past seven days were reported in Middlesex County, or 52.33 cases per 100,000 people.

Fairfield, Windham and Tolland counties were added Friday to the CDC’s list of areas with “substantial” COVID spread, joining New Haven, Hartford and New London counties.

Litchfield County remains at a “moderate” level of coronavirus transmission, according to the CDC. Over the past seven days, 70 cases, or 38.82 per 100,000 people, have been reported there.

The CDC recommends that fully vaccinated people “wear a mask in public indoor settings” in areas of substantial or high transmission.

The state Department of Public Health advised Friday that anyone over the age of 2 who lives, works or travels through counties with substantial spread should wear a mask in indoor public settings.

State residents with underlying medical conditions that put them at risk from the virus, or people who live with people at high risk, should wear masks indoors, the agency said.

Connecticut’s upward trend of COVID-19 cases and hospitalizations continued Friday.

The state numbers showed a daily positivity rate of 2.72 percent as 491 new infections were diagnosed out of 18,025 tests.

Four more patients increased the state’s hospitalization total to 116.
