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 continues to be low. See national influenza statistics through Flu View.
