On July 2, the Department of Environmental Protection reported mosquitoes in Beaver and Delaware counties were the first to test positive for West Nile Virus this season.

The positives occurred in Center Township, Beaver County and Upper Darby Township, Delaware County.

DEP and Delaware County staff will respond as needed to these findings.

In 2018, the Department of Health reported 8 deaths from West Nile Virus to the U.S. Centers for Disease Control and Prevention.

Certain mosquito species carry the West Nile virus, which can cause humans to contract West Nile encephalitis, an infection that can result in an inflammation of the brain. According to the Department of Health, all residents in areas where virus activity has been identified are at risk of contracting West Nile encephalitis.

Individuals can take a number of precautionary measures around their homes to help eliminate mosquito-breeding areas, including:

-- Dispose of cans, buckets, plastic containers, ceramic pots, or similar containers that hold water.

-- Properly dispose of discarded tires that can collect water. Stagnant water is where most mosquitoes breed.

-- Drill holes in the bottom of outdoor recycling containers.

-- Have clogged roof gutters cleaned every year as the leaves from surrounding trees have a tendency to plug drains.

-- Turn over plastic wading pools when not in use.

-- Turn over wheelbarrows and don't let water stagnate in birdbaths.

-- Aerate ornamental pools or stock them with fish.

-- Clean and chlorinate swimming pools not in use and remove any water that may collect on pool covers.

If a resident has stagnant pools of water on their property, they can buy Bti (short for Bacillus thuringiensis subspecies israelensis) products at lawn and garden, outdoor supply, home improvement and other stores. This naturally occurring bacterium kills mosquito larvae, but is safe for people, pets, aquatic life and plants.

Additionally, these simple precautions can prevent mosquito bites, particularly for people who are most at risk:

-- Make sure screens fit tightly over doors and windows to keep mosquitoes out of homes.

-- Consider wearing long-sleeved shirts, long pants and socks when outdoors, particularly when mosquitoes are most active at dawn and dusk, or in areas known for having large numbers of mosquitoes.

-- When possible, reduce outdoor exposure at dawn and dusk during peak mosquito periods, usually April through October.

-- Use insect repellents according to the manufacturer's instructions. An effective repellent will contain DEET, picardin, or lemon eucalyptus oil. Consult with a pediatrician or family physician for questions about the use of repellent on children, as repellent is not recommended for children under the age of two months.
