West Nile Virus Risk Elevated Across Massachusetts
BOSTON, MA – Mosquitoes carrying West Nile virus continue to pose a notable risk to public health in several Massachusetts communities, with 445 positive samples detected this season, state officials report. While no human or animal cases have been confirmed as of today, the ongoing presence of the virus underscores the importance of preventative measures as the fall season approaches.
West Nile virus, spread through the bite of infected mosquitoes, can cause serious illness in humans adn animals. While most infections are mild, symptoms can include fever, headache, and body aches. In rare cases, the virus can lead to encephalitis or meningitis, potentially resulting in long-term neurological complications or even death. The Massachusetts Department of Public Health is closely monitoring the situation and urges residents to take precautions against mosquito bites.
Along with West Nile virus, eastern equine encephalitis (EEE) has also been detected in the state this year, with 23 EEE-positive mosquito samples identified. Though no human or animal cases of EEE have been reported, the disease carries a high mortality rate – approximately 30 percent of severe cases are fatal – and can leave survivors with lasting neurological damage, according to the Centers for disease Control and Prevention (CDC).
Public health officials recommend that Massachusetts residents regularly consult the Massachusetts Arbovirus Update page (https://www.mass.gov/info-details/massachusetts-arbovirus-update) for daily updates on risk levels in their communities and the latest details on both West Nile virus and EEE. The page provides crucial data to help residents stay informed and protect themselves.
