Massachusetts Mosquitoes Test Positive for West Nile and Eastern Equine Encephalitis Viruses
Deadly EEE Virus Returns to Massachusetts
Eastern equine encephalitis (EEE) virus, a potentially fatal mosquito-borne disease, has been detected in mosquito samples collected in Carver, Massachusetts. This marks the first detection of EEE virus in the state this year.
EEE virus infection can cause severe neurological symptoms, including fever, headache, muscle weakness, and disorientation. In severe cases, it can lead to brain inflammation and even death. In 2019, there were 12 human cases of EEE in Massachusetts, and six people died.
West Nile Virus Also Detected
In addition to EEE virus, West Nile virus (WNV) has also been detected in mosquito samples from Massachusetts. WNV infection typically causes milder symptoms than EEE, but it can still be serious, especially in people over 50 years old or with weakened immune systems.
No human cases of WNV or EEE have been reported in Massachusetts so far this year. However, the detection of these viruses in mosquito samples indicates that the risk of infection is present.
Moderate Risk Level in Carver and Kingston
The Massachusetts Department of Public Health (MDPH) has elevated the risk level for EEE to moderate in the communities of Carver and Kingston. This means that residents and visitors in these areas should take precautions to avoid mosquito bites.
Prevention Measures
The best way to prevent mosquito-borne diseases is to avoid mosquito bites. Residents and visitors in Massachusetts should take the following precautions:
- Wear long sleeves and pants when outdoors, especially at dusk and dawn when mosquitoes are most active.
- Use insect repellent containing DEET, picaridin, IR3535, or oil of lemon eucalyptus.
- Eliminate standing water around your home, where mosquitoes can breed.
- Repair or replace window and door screens.
If you experience symptoms of EEE or WNV infection, such as fever, headache, or muscle weakness, seek medical attention immediately.
