Conn. (WTNH) — According to the Centers for Disease Control and Prevention’s (CDC) COVID-19 community levels map, six of Connecticut’s eight counties are in the high categories.

The map, which launched in February, shows a color-coded system of “low,” “medium,” and “high” levels. A week ago, Fairfield, Litchfield, New London, Windham, and Tolland counties were listed in the medium or yellow counties.

As of Thursday evening, only Fairfield and New London counties are listed in the medium category, meaning Hartford, Middlesex, New Haven, Litchfield, Windham, and Tolland are now in the high/orange category.

“This latest update comes as no surprise considering the trajectory that this latest omicron sub-variant is taking,” Connecticut Department of Public Health Commissioner Manisha Juthani, MD, said in a statement. “And I cannot stress enough that the tools to combat this virus are in place and easily accessible.”

Junathi said these tools include vaccines, booster shots, Test to Treat locations, therapeutics, self-tests, and state-supported testing.

The DPH urges residents in the high category to wear a mask indoors in public, while those at high risk for severe illness in counties in the medium category should talk to their healthcare providers about when to wear a mask. Residents in both the high and medium category counties are urged to stay up-to-date with vaccines and get tested if they have symptoms.
