"Although no human cases of the virus have been confirmed in Oakland County this year, residents are urged to be cautious when spending time outdoors," Kathy Forzley, Oakland County Health Division manager/health officer, said in a news release.

"The most effective way to protect yourself and your family against West Nile Virus is to take precautions against mosquito bites."
Follow these tips to prevent a mosquito bite:

• Spray clothing and exposed skin with insect repellent. The Centers for Disease Control and Prevention (CDC) recommends use of insect repellents containing active ingredients registered with the U.S. Environmental Protection Agency (EPA). Two products registered with the EPA that have shown a high degree of effectiveness are DEET and Picaridin. Always follow manufacturer’s directions carefully, especially when using on children.
• Minimize activities where mosquitoes are present, such as shaded areas.
• Wear long-sleeved shirts and long pants outdoors.
• Maintain window and door screening to keep mosquitoes out of buildings.
• Eliminate standing water in your yard. Empty water from mosquito breeding sites, such as flower pots, pet bowls, clogged rain gutters, swimming pool covers, discarded tires, buckets, barrels, cans, and similar items in which mosquitoes can lay eggs.
• To report a single (1) dead bird, visit www.michigandnr.com/diseasedwildlifereporting/disease_obsreport.asp. To report three (3) or more dead birds call (517) 336-5030.

WNV is a mosquito-borne virus that can cause inflammation and swelling of the brain. Mosquitoes are infected by biting a bird that carries the virus.

However, in some individuals, particularly the elderly, a much more serious disease affecting the brain tissue can develop.
