Four cases of the Powassan virus, a tick-borne illness, have been confirmed in Connecticut. The patients, two men aged 60 years and older from Middlesex and Litchfield counties, and two women aged 50 years and older from Windham and Litchfield counties, were all found to have antibodies to Powassan through laboratory tests. The individuals reported being bitten by ticks and were hospitalized with central nervous system diseases. However, they have since been discharged and are recovering.
The Connecticut Department of Public Health is urging residents to take precautions against tick bites. In recent years, there has been a higher than usual number of ticks, resulting in increased cases of tick-borne illnesses. The Connecticut Tick and Tick-borne Pathogen Surveillance Program has received a high number of tick submissions this year, indicating the potential for further spread of tick-borne diseases.
From 2016 to 2022, 19 cases of Powassan-associated illnesses were reported in Connecticut, with six cases already reported in 2022. Tragically, two of the infections in the previous year resulted in fatalities. Powassan is transmitted through the bite of an infected blacklegged tick. Symptoms of the virus may take one week to one month to develop and can range from mild flu-like illness to severe central nervous system complications.
At present, there is no vaccine or specific treatment for Powassan-associated illnesses. Supportive therapy, which may include hospitalization, respiratory support, and hydration, is used to treat severe cases. The Centers for Disease Control and Prevention (CDC) website provides additional information on the virus.
Tick-borne illnesses continue to present a growing public health challenge. It is crucial for individuals to take preventive measures, such as wearing protective clothing, using insect repellent, conducting regular tick checks, and avoiding high-risk areas. By staying informed and taking necessary precautions, residents can reduce their risk of contracting tick-borne diseases like Powassan.
