A mosquito carrying the West Nile virus was found in Malden after testing of a pool of the insects on Aug. 8, according to the city.
A pool of 121 mosquitoes tested in the area of Lynn Street and Route 1 found one was carrying the West Nile Virus, the announcement said.
The virus can be passed to humans through mosquito bites. The virus can cause fever, and in severe cases, meningitis or encephalitis.
Positive tests also have been found in the nearby communities of Lynn, Melrose, and Saugus.
The city's Board of Health has passed along the following tips:
Avoid Mosquito Bites: Peak Mosquito biting hours are from dusk to dawn. 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.
Protective 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 containing the ingredient DEET when you go outdoors.
Mosquito-Proof Your Home: Drain standing water. Mosquitos 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. Install or Repair Screens. Keep mosquitos outside by having tightly-fitting screens on all of your windows and door.
