DEP and west nile virus staff are responding with additional surveillance and control as needed, according to information from officials. The disease has also already been found in mosquitos in Bucks and Chester counties this season.
According to the Centers for Disease Control and Prevention, West Nile is transmitted via mosquitos and there are currently no medications to treat or vaccines to prevent WNV infection.
“Fortunately, most people infected with WNV will have no symptoms. About 1 in 5 people who are infected will develop a fever with other symptoms. Less than 1 percent of infected people develop a serious, sometimes fatal, neurologic illness,” the CDC website says.
The best thing residents can do is get rid of standing water where mosquitoes can breed on their property, according to experts.
Here are more tips to reduce exposure to West Nile:
• 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 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.
• 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.
