IPSWICH — Town Manager Anthony Marino and Public Health Director Colleen Fermon announce that an Ipswich resident in their 70s has tested positive for West Nile virus (WNV).
This is the first confirmed human case of WNV in Ipswich in 2021. As a result of the positive human case, the Massachusetts Department of Public Health (DPH) has elevated Ipswich to amoderate-risk level for human infection.
The DPH also announced a second positive case, an individual in their 60s who lives in Middlesex County.
The Town of Ipswich is taking the following pro-active steps:
- Northeast Massachusetts Mosquito Control is conducting additional larviciding of areas within proximity of case for source reduction.
- Mosquito collection will be increased within proximity of case to allow for additional mosquito testing.
“We ask our residents and those who live in surrounding communities to protect themselves, especially those who are among our most vulnerable populations,” Director Fermon said.
Mosquitoes are most prevalent from May to August, but remain active until the first time temperatures fall below freezing. According to the Massachusetts Department of Public Health, mosquito bites in the state typically result in skin irritation and itching.
However, serious diseases including West Nile also are spread by mosquitoes in rare instances. These viruses can cause illness ranging from a mild fever to more serious disease like encephalitis or meningitis.
West Nile virus was first detected in the United States in 1999. Since the majority of those exposed to West Nile virus have no symptoms, it’s difficult to identify exactly how many people have been infected. Only those who develop severe illnesses with West Nile virus are often reported.
In 2020, there were five human cases of WNV infection identified in Massachusetts. This year, there are now six WNV cases involving humans, and one involving an alpaca.
The Town of Ipswich encourages residents to follow these tips provided by the DPH:
- Use insect repellent with DEET any time you are outdoors. Be sure to follow the application directions on the label.
- Be aware of peak mosquito hours, which are generally from dusk to dawn. Residents who are ages 50 and older, or those who are immunocompromised, should limit outdoor activities from dusk to dawn.
- Wear protective clothing when outdoors during peak mosquito hours such as long sleeves, long pants, high socks, hats with netting to cover the face, and any other clothing that will cover exposed skin.
- Use mosquito netting around baby carriages or child playpens when your baby is outdoors.
- Make sure screens are repaired and are tightly attached to doors and windows.
- Remove standing water from places such as puddles, ditches, bird baths and gutters, which are breeding grounds for mosquitoes.
The Town of Ipswich also wishes to share the following tips from the Centers for Disease Control and Prevention:
- Apply sunscreen first and insect repellent second.
- Do not apply insect repellent on the skin beneath clothing.
- Consider buying permethrin-treated clothing and gear, or using permethrin to treat your clothing and gear. Do not use permethrin products directly on skin.
- Use an indoor insect fogger or indoor insect spray to kill mosquitoes and treat areas where they rest. Always follow label instructions.
- To prevent mosquito bites when traveling overseas, choose a hotel or lodging with air conditioning or screens on windows and doors, or sleep under a mosquito bed net if you are outside or in a room that does not have screens.
Parents, guardians and caregivers of babies and children are advised:
- Dress children in long layers to cover their arms and legs.
- Use mosquito netting to cover strollers and baby carriers outdoors.
- When using insect repellent on a child, follow instructions on the label and never use products that contain oil of lemon eucalyptus or para-menthane-diol on children under 3 years old.
- NEVER apply insect repellent on a child’s hands, eyes, mouth, cuts, or irritated skin. To apply insect repellent to a child’s face, carefully spray it onto your hands and apply it to the skin.
