No human or animal cases of WNV or Eastern equine encephalitis (EEE) have been detected so far this year, Mass DPH said. There were 19 human cases of WNV and four human cases of EEE in 2024.
The virus is typically transmitted to humans through the bite of an infected mosquito and can infect people of all ages. People over the age of 50 are at higher risk for severe disease. Most people infected with the virus will experience no symptoms, however symptoms can include fever and flu-like illness.
You can protect yourself from WNV by taking precautions to avoid mosquito bites. Apply insect repellent when outdoors, be aware of peak mosquito hours from dawn to dusk, and consider rescheduling outdoor activities planned for evening or early morning hours.
It is also important to mosquito-proof your home by draining any standing water where the insects might lay their eggs and make sure to install or repair any screens as needed.
