COVID-19 Community Levels Map Update, Jan. 20, 2023: The CDC has listed six Connecticut Counties—Hartford, Litchfield, Middlesex, New Haven, Tolland and Windham Counties—in the High/Orange category as part of its weekly COVID-19 Community Levels update. Fairfield and New London Counties are listed in the Medium/Yellow category.  Because all eight Connecticut counties are either in the High or Medium categories, the Connecticut Department of Public Health recommends that all residents consider wearing a mask in public indoor spaces. People who are at high risk for severe illness should consider additional measures to minimize their exposure to COVID-19 and other respiratory illnesses.
