The Warren County Health Department is reporting the first human case of West Nile virus in a resident from Warren County. Please make sure that you are protecting yourself from mosquitoes. Be aware that mosquitoes will remain active until the first frost.

West Nile virus is transmitted through the bite of a mosquito that has picked up the virus by feeding on an infected bird. Common West Nile virus symptoms include fever, nausea, headache, and muscle aches. Symptoms may last from a few days to a few weeks. However, four out of five people infected with West Nile virus will not show any symptoms. In rare cases, severe illness including meningitis or encephalitis, or even death, can occur. People over age 50 are at higher risk for severe illness from West Nile Virus.

West Nile Virus is not transmitted from person to person.

The best way to prevent West Nile disease or any other mosquito-borne illness is to reduce the number of mosquitoes around your home and to take personal precautions to avoid mosquito bites. Precautions include practicing the three “R’s” – reduce, repel, and report.

REDUCE exposure – avoid being outdoors when mosquitoes are most active, especially between dusk and dawn.

Make sure doors and windows have tight-fitting screens. Repair or replace screens that have tears or other openings. Try to keep doors and windows shut, especially at night.

Eliminate all sources of standing water where mosquitoes can breed, including water in bird baths, ponds, flowerpots, wading pools, old tires and any other receptacles.

REPEL – when outdoors, wear shoes and socks, long pants and a long-sleeved shirt, and apply insect repellent that contains DEET, picaridin, oil of lemon eucalyptus or IR3535, according to label instructions. Consult a physician before using repellents on infants.

REPORT – In communities where there are organized mosquito control programs, contact your municipal government to report areas of stagnant water in roadside ditches, flooded yards and similar locations that may produce mosquitoes.
