BOSTON (WWLP) – The Massachusetts Department of Public Health has announced that the first case of West Nile Virus this year was found in a mosquito sample.
According to the DPH, the WNV infection was confirm on July 16th; the mosquito sample was collected on July 8th in the Town of Sheffield. No cases of WNV, or Easter Equine Encephalitis, have been found in a human or animal so far this year.
Health officials have not changed the risk level since the findings. WNV is usually transmitted to humans through the bite of an infected mosquito. In 2014, there were six human cases of WNV infection identified in Massachusetts.
While WNV can infect people of all ages, people over the age of 50 are at higher risk for severe disease. Most people infected with WNV will have no symptoms. When present, WNV symptoms tend to include fever and flu-like illness. In rare cases, more severe illness can occur.Below are tips from the Massachusetts Department of Public Health on how to avoid mosquitoes borne illnesses:Avoid Mosquito Bites
Apply Insect Repellent when Outdoors: Use a repellent with DEET (N, N-diethyl-m-toluamide), permethrin, picaridin (KBR 3023), oil of lemon eucalyptus [p-methane 3, 8-diol (PMD)] or IR3535 according to the instructions on the product label.
DEET products should not be used on infants under two months of age and should be used in concentrations of 30% or less on older children. Oil of lemon eucalyptus should not be used on children under three years of age.
Be Aware of Peak Mosquito Hours: The hours from dusk to dawn are peak biting times for many mosquitoes. Consider rescheduling outdoor activities that occur during evening or early morning.
Clothing Can Help Reduce Mosquito Bites: Wearing long-sleeves, long pants and socks when outdoors will help keep mosquitoes away from your skin.Mosquito-Proof Your Home
Drain Standing Water: Mosquitoes lay their eggs in standing water. Limit the number of places around your home for mosquitoes to breed by either draining or discarding items that hold water. Check rain gutters and drains. Empty any unused flowerpots and wading pools, and change water in birdbaths frequently.
Install or Repair Screens: Keep mosquitoes outside by having tightly-fitting screens on all of your windows and doors.Protect Your Animals
Animal owners should reduce potential mosquito breeding sites on their property by eliminating standing water from containers such as buckets, tires, and wading pools – especially after heavy rains.
Water troughs provide excellent mosquito breeding habitats and should be flushed out at least once a week during the summer months to reduce mosquitoes near paddock areas.
Horse owners should keep horses in indoor stalls at night to reduce their risk of exposure to mosquitoes. Owners should also speak with their veterinarian about mosquito repellents approved for use in animals and vaccinations to prevent WNV and EEE.
If an animal is diagnosed with WNV or EEE, owners are required to report to DAR, Division of Animal Health by calling 617-626-1795 and to the Department of Public Health (DPH) by calling 617-983-6800.
