State Health Officials Report Two New West Nile Virus Cases
West Nile Virus Warning Issued Across Massachusetts Counties
Understanding the West Nile Virus Threat
The US Centers for Disease Control and Prevention reports that while most individuals infected with the West Nile virus remain asymptomatic, those who do exhibit symptoms may experience severe health issues. These can include high fever, disorientation, coma, tremors, convulsions, vision loss, numbness, or paralysis.
Increased Risk in Key Massachusetts Areas
The Massachusetts Department of Public Health has indicated a significant increase in risk levels for West Nile virus across various counties. The municipalities within Suffolk, Middlesex, Essex, and Worcester counties currently face a high risk. Meanwhile, 210 cities and towns across the Barnstable, Berkshire, Bristol, Essex, Franklin, Hampden, Hampshire, Middlesex, Norfolk, Plymouth, Suffolk, and Worcester counties are at moderate risk.
Public Health Protection Measures
Robbie Goldstein, the state’s public health commissioner, emphasizes the importance of continued vigilance as the peak season for West Nile virus approaches its end. However, until the first hard frost, the risk remains, and residents are encouraged to take preventive measures:
- Use mosquito repellent.
- Wear long sleeves and pants to minimize skin exposure.
Monitoring Mosquito Activity
The first West Nile-positive mosquitoes in Massachusetts were identified on June 17. Since then, the Department of Public Health reports that one animal case involving a goat has been confirmed this year. A total of 445 mosquito samples have tested positive.
Eastern Equine Encephalitis Also Detected
Another mosquito-borne virus, Eastern equine encephalitis (EEE), has been detected in Massachusetts, with 23 EEE-positive mosquito samples recorded. Thankfully, there have been no reported human or animal cases this year. Despite the relatively low incidence of EEE infection in humans, it poses a significant threat due to its severe impact; around 30 percent of severe cases can be fatal, with many survivors suffering ongoing neurological issues.
Stay Informed with the Massachusetts Arbovirus Update
Residents are urged to regularly consult the Massachusetts Arbovirus Update page. This resource provides daily updates on risk levels throughout the state and information on new cases of both the West Nile virus and EEE, helping the public stay informed and protected.
