Mosquito Pool in Oakland County Tests Positive for West Nile Virus

PONTIAC, MI – The first mosquito pool in Oakland County tested positive for West Nile virus (WNV). No human cases of the virus have been confirmed in Oakland County yet this year.

Oakland County residents are urged to protect themselves from the threat of WNV by taking necessary precautions.

“WNV is typically detected from June through September.” said Leigh-Anne Stafford, health officer for Oakland County Health Division. “Prevention is the best way to avoid the spread of mosquito-borne diseases.”

Follow these tips to prevent mosquito bites:
• Use insect repellent. The Centers for Disease Control and Prevention (CDC) recommends the use of insect repellents containing active ingredients registered with the U.S. Environmental Protection Agency (EPA). Always follow manufacturer’s directions carefully.
• Be careful using repellent on the hands of children because repellents may irritate the eyes and mouth.
• Wear protective clothing such as long sleeved shirts and pants.
• Limit outdoor activity from dusk to dawn when mosquitoes are most active.
• Maintain window and door screens to keep mosquitoes out of buildings.
• Get rid of mosquito breeding sites by emptying standing water that collects in birdbaths, boats, buckets, tires, unused pools, roof gutters and other containers.

WNV is a mosquito-borne virus; mosquitoes are infected by biting a bird that carries the virus, and the virus is then spread to humans through the bite of the infected mosquito. Most people who are infected with the virus have either no symptoms or experience a mild illness such as fever, headache, and body aches. However, in some individuals – particularly the elderly – a more serious disease causing inflammation and swelling of the brain can develop.
