COVID-19 Community Levels Map Update, Jan. 27, 2023: The CDC has listed three Connecticut Counties—Litchfield, Middlesex and New Haven Counties—in the High/Orange category as part of its weekly COVID-19 Community Levels update. Fairfield, Hartford, New London, Tolland and Windham 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. Visit the CDC COVID-19 Community Levels Map for updates.

Connecticut Seasonal Influenza Statistics

Influenza (flu) is a respiratory illness caused by influenza viruses. This contagious disease can cause mild to severe symptoms that may require hospitalization. Certain health conditions (asthma, diabetes, heart disease, etc.) can result in a higher risk of getting sick with influenza. Age may also play a role in who gets sick and has more severe symptoms. To learn about how to prevent getting sick with influenza, visit the Centers for Disease Control and Prevention.

 

In Connecticut, the DPH uses multiple surveillance systems to monitor circulating influenza viruses. Seasonal flu viruses can be detected throughout the year; however, seasonal flu activity generally begins as early as October and November and can continue through late May. The weekly surveillance reports show how this year's flu season is developing. Each report is progressive and includes data starting from the beginning of this flu season.

 

Statewide influenza activity is increasing. See national influenza statistics through Flu View.

 

A type of influenza affecting birds, known as Highly Pathogenic Avian Influenza (HPAI), has been found in wild birds in several Connecticut counties and in a small farm in Connecticut, see HPAI in CT. These viruses pose little risk to people although the CDC has now identified a human case in Colorado, see U.S. Case of Human Avian Influenza Reported.
