A mosquito sample from Massac County returned positive for the West Nile Virus (WNV) on Aug. 14, according to the Southern Seven Health Department.
A positive means that one of the mosquitoes tested was carrying the West Nile virus.
According to Southern Seven, however, a mosquito may fly up to 15 miles in search of a blood meal and the exact area where the mosquito contracted the virus cannot be determined.
Southern Seven would like to remind the public that West Nile still presents a public danger especially during this time of year.
West Nile is transmitted when a mosquito feeds on an infected bird and then feeds on a human host.
Only two in 10 people infected with West Nile will show symptoms of the disease. Those adults 50 years and older are the ones most likely to exhibit symptoms of the disease.
The most effective way to avoid WNV Disease is to prevent mosquito bites:
• Use insect repellants when going outdoors. Repellants containing at least 25 percent to 35 percent DEET, the active ingredient in mosquito repellant, should be applied to clothing and especially to bare skin.
• Wear long sleeves and pants from dusk through dawn when many mosquitoes are most active.
• Install or repair screens on windows and doors. If an individual has it, use air conditioning.
• Help reduce the number of mosquitoes around the home. Empty standing water from containers such as flowerpots, gutters, buckets, pool covers, pet water dishes, discarded tires and birdbath.
