EEE and Mosquito Bite Prevention

As the summer transitions into fall, it’s important for all of us at the College of the Holy Cross to stay informed and vigilant about the risks posed by Eastern Equine Encephalitis (EEE). While Massachusetts is beautiful this time of year, it’s also the peak season for mosquitoes, which can carry and transmit EEE—a VERY rare but serious virus.

What is EEE?

Eastern Equine Encephalitis (EEE) is a viral infection transmitted by mosquitoes.  Massachusetts has experienced periodic outbreaks of EEE, and it’s crucial to take preventive measures, especially in regions where the virus has been detected.

Worcester is currently LOW risk with 4 surrounding towns at MODERATE risk.

Mosquito Bite Prevention Tips

To minimize your risk of mosquito bites and potential exposure to EEE, follow these simple yet effective prevention strategies:

  1. Avoid Peak Mosquito Hours: Mosquitoes that carry EEE are most active from dusk to dawn. Try to limit outdoor activities during these times, especially in areas with dense vegetation or standing water.
  2. Wear Protective Clothing: When outdoors, wear long sleeves, long pants, and socks to reduce the amount of exposed skin. Light-colored clothing is less attractive to mosquitoes.
  3. Use Insect Repellent: Apply an EPA-registered insect repellent containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin and clothing. Always follow the instructions on the label.
  4. Protect Your Living Space: Keep windows and doors closed or make sure screens are in place especially from dusk to dawn.
  5. Stay Informed: Follow Health Services on Instagram @hc_healthservices for timely updates and on IGNITE!

Symptoms of EEE

While most people bitten by an infected mosquito will NOT develop EEE or the symptoms of EEE, those who do may experience:

  • Sudden onset of a very high fever (103-106F)
  • Headache
  • Chills
  • Vomiting
  • Disorientation
  • Seizures

If you experience any of these symptoms, especially after a mosquito bite, seek medical attention immediately.

What is the College Doing?

The College of the Holy Cross is committed to the health and safety of its students. We are actively monitoring mosquito activity in and around the Worcester area and the recommendations of the MA Department of Public Health.

The City of Worcester has planned mosquito spraying on 4 dates in September. You can find spraying plans and updated information here: https://www.cmmcp.org/
