"Of the mosquito-borne diseases, West Nile virus is the most common one in the continental United States. It is imperative that Pennsylvania residents take common-sense precautions to protect themselves from mosquitoes", said DEP Secretary Patrick McDonnell. Mosquitoes become the carrier of the West Nile Virus after they feed on the blood of an infected bird. The rain and flooding often leave standing pools of water, creating ideal mosquito breeding grounds. "It takes only a small amount of standing water - in a bird bath, in an old auto tire, in overturned lids, in empty pots, anywhere - to provide a breeding ground for mosquitoes".

Given the exceptionally wet summer, it was perhaps no surprise: The Fairfax County Health Department on August 2 announced it had identified the first reported human case of West Nile virus in the county for 2018. Keep in mind to drain water from tires, cans, flowerpots, clogged rain gutters, rain barrels, toys and puddles.

People from Manitoba are advised to use mosquito repellent, wear long-sleeved white clothes and try to stay indoors at dusk and dawn. Officials also say that they have been getting more mosquitoes than usual in traps that are set out around the county.

Use of commonly sold insect repellents, like those using DEET, Picaridin, or other EPA-registered repellents, can also cut down on mosquito bites and possible exposure to the virus.

The virus can cause a variety of symptoms in humans, including headache, body aches, joint pains, vomiting, diarrhea and rash, although most infected people (about 80 percent) do not develop any symptoms, according to the U.S. Centers for Disease Control. While most make a full recovery, severe cases can lead to meningitis, encephalitis, paralysis and, in the most extreme cases, to death.
