The Maricopa County Environmental Services Department has confirmed the first positive mosquito sample of the West Nile virus in northeast Mesa.
Officials say the virus is transmitted to humans by the bite of an infected mosquito.
"Through our routine year-round surveillance of collecting and testing mosquitoes throughout the county, the West Nile virus positive mosquito sample was discovered," said Steven Goode, Maricopa County Environmental Services Director in a news release.
Officials are reminding the public to rid your homes of any standing water where mosquitoes can breed.
Twenty percent of people infected by the virus experience flu-like symptoms three to 15 days after the mosquito bite, according to officials.
Symptoms of the virus may include headache, fever, nausea, vomiting, swollen lymph glands and skin rash.
County officials say a small percentage of those infected may experience more severe symptoms including meningitis, encephalitis, paralysis or death.
Those over the age of 50 are at a higher risk for severe symptoms.
If you think you have symptoms of the West Nile virus you are urged to consult with your health care provider.
