A concerning development has been confirmed by the Massachusetts Department of Public Health (MDPH): the first human case of West Nile virus (WNV) in the state for 2024. It was in Hampden County that the man, in his 40s, contracted the virus. The first animal incidence of Eastern Equine Encephalitis (EEE), a more serious mosquito-borne sickness, in the state was recently discovered in a horse exposed in Plymouth County.

The necessity of increased awareness against mosquito-borne illnesses in Massachusetts is highlighted by the confirmation of both WNV and EEE cases. Even though WNV usually only results in minor symptoms like fever, headaches, body pains, and exhaustion, it can occasionally cause serious neurological conditions. On the other hand, EEE is a much more deadly illness and much more harmful.

“The state’s discovery of both Eastern Equine Encephalitis and the West Nile virus is a severe concern, according to Public Health Commissioner Robert Goldstein, MD, PhD. “We urge the people to protect their families and themselves from mosquito bites by taking preventive action.”

The risk of infection rises in the warmer months due to mosquito-borne transmission of WNV and EEE. The MDPH suggests the following actions to avoid mosquito bites:

• Use insect repellent: Apply insect repellent in accordance with product instructions, making that it contains DEET, picaridin, oil of lemon eucalyptus, or IR3535. It should be EPA listed.
• Wear protective gear: Put on long sleeves, long pants, socks, and shoes when you’re outside.
• Take extra care outdoors: Since mosquitoes are most active at dark and dawn, exercise additional caution when you’re outside. Cut down on the time you spend outside at these times.
• Eliminate any standing water: Standing water attracts mosquitoes and should be cleared out. Any pots or bird baths that contain water should be emptied, as well as old tires.
• Repair screens: To keep mosquitoes out of your home, make sure the screens on your doors and windows are in good condition.

In many counties—Berkshire, Bristol, Hampden, Hampshire, Middlesex, Norfolk, Plymouth, Suffolk, and Worcester—the MDPH has categorized the risk of WNV as moderate. Residents of the state should exercise caution even if the danger for EEE is now low in Dennis and high in Plymouth County.

The detection of these instances has been made possible by the state’s early warning system for diseases spread by mosquitoes, which involves testing for viruses and keeping an eye on mosquito populations. As needed, MDPH will give updates while keeping a careful eye on the situation.

Residents must act proactively to safeguard themselves and their children from these potentially harmful diseases as the mosquito season deepens. People can considerably lower their chance of infection by taking the advised precautions.
