"Every single summer we have mosquitoes with West Nile virus in Bucks County", David Damsker, the director of the county's Department of Health, said. The positive sample was the first this year in Clark County, but the county has had positive mosquito samples for several years.
No identified human cases of West Nile Virus infections reported in Clark County. "However, West Nile virus can cause serious complications, including neurological diseases, and can also cause a milder flu-like illness with headache, fever and fatigue, weakness and sometimes rash".
"There are simple precautions you can take to protect yourself and your family from mosquito bites when outside - wear insect repellent and cover your arms and legs, especially at dawn or dusk". People most at risk of WNV include elderly people who are often outside walking where they are bitten by a mosquito and people who are immunocompromised because of medications or illness.
The health unit starts trapping adult mosquitoes and testing for West Nile in the last week of June.
Apply an EPA-registered insect repellent containing DEET, picaridin, IR3535, oil of lemon eucalyptus or para-menthane-diol to clothes and exposed skin.
Clean roof gutters and downspouts for proper drainage. However, most mosquitoes do not carry the virus and the virus is not spread through person to person contact or directly from birds to humans. Of the 153 West Nile cases, 48 presented with meningitis, 53 with encephalitis, and 5 with paralysis.
In response to the Rossville discovery, the Health Department says it is increasing mosquito surveillance in the surrounding area by installing additional mosquito monitoring traps.
