The information below was issued by the Town of Ashland.

West Nile Virus is most commonly transmitted to humans by the bite of an infected mosquito. The mosquitoes that carry this virus are common throughout the state, and are found in urban as well as more rural areas.

While West Nile can infect people of all ages, people over the age of 50 are at higher risk for severe infection.

By taking a few, common-sense precautions, people can help to protect themselves and their loved ones:

  • Avoid Mosquito Bites
  • 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. If you are outdoors at any time and notice mosquitoes around you, take steps to avoid being bitten by moving indoors, covering up and/or wearing repellant.
  • Clothing Can Help reduce mosquito bites. Although it may be difficult to do when it’s hot, wearing long-sleeves, long pants and socks when outdoors will help keep mosquitoes away from your skin.
  • Apply Insect Repellent when you go outdoors. Use a repellent with DEET (N, N-diethyl-m-toluamide), permethrin, picaridin (KBR 3023), IR3535 or oil of lemon eucalyptus [p-methane 3, 8-diol (PMD)] 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. Permethrin products are intended for use on items such as clothing, shoes, bed nets and camping gear and should not be applied to skin.

Mosquito-Proof Your Home

  • Drain Standing Water – Many mosquitoes lay their eggs in standing water. Limit the number of places around your home for mosquitoes to breed by either draining or getting rid of 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 – Some mosquitoes like to come indoors. Keep them outside by having tightly-fitting screens on all of your windows and doors.

What is West Nile Virus (WNV)?
West Nile virus (WNV) is a mosquito-carried virus that can cause illness ranging from a mild fever to more serious disease like encephalitis or meningitis. It was first identified in the United States in 1999.

How is WNV spread?
WNV is most commonly spread to people through the bite of an infected mosquito. More information about
different types of mosquitoes that can spread WNV can be found on the MDPH website at
WNV may also be spread through blood transfusion or organ transplant. In addition, there are rare reports of
WNV being passed from pregnant or breastfeeding women, who are infected with WNV, to their babies. Since
these reports are rare, the health effects on an unborn or breastfeeding baby are unclear and still being studied.
People do not become infected by having direct contact with other infected people, birds or animals.

What are the symptoms of WNV?
The majority of people who are infected with WNV (approximately 80%) will have no symptoms.
A smaller number of people who become infected (~ 20%) will have symptoms such as fever, headache, body
aches, nausea, vomiting, and sometimes swollen lymph glands. They may also develop a skin rash on the chest,
stomach and back.
Less than 1% of people infected with WNV will develop severe illness, including encephalitis or meningitis.
The symptoms of severe illness can include high fever, headache, neck stiffness, stupor, disorientation, coma,
tremors, convulsions, muscle weakness, vision loss, numbness and paralysis. Persons older than 50 years of age
have a higher risk of developing severe illness.

How common is WNV in Massachusetts?
Because most people who are exposed to WNV have no symptoms, it is difficult to know exactly how many people have been infected.

People who develop severe illness with WNV are most often reported.

Between 2008 and 2017, 81 people were reported with WNV infection in Massachusetts. Four of these people died. Cases have been identified from around the state.
