The Mississippi State Department of Health says the case is in Pearl River County.
The risk of West Nile is lower in the spring but rises through the early and midsummer months and usually reaches peak transmission during July, August, and September.
Joel Ardoin, Emergency Management Coordinator in Orange County, has confirmed there is one case of West Nile Virus in a human in Orange County. One in five people who are infected develop a fever with a headache or body aches.
In 2017, there were 20 human cases of West Nile virus reported in Pennsylvania.
Steps to avoid contracting West Nile include using insect repellent with DEET, wearing long-sleeved, light coloured shirts, trousers and a hat while doing activities outdoors, or staying inside at dawn and dusk when mosquitoes are most active.
Infected mosquitoes pass the virus to birds, animals and people, DEP said.
"[Clay County Mosquito Control's] plan and response to this positive test is to elevate mosquito control in the Keystone Heights area, as well as to continue on throughout the entire county", said Rollins.
Recent samples collected from the West End and North Side have tested positive for the virus, according to the health department. These symptoms generally appear two to 14 days following the bite of an infected mosquito.
On the other hand, some people, especially young children, older adults, and people with impaired immune systems, might develop encephalitis and meningitis. Many people may not realize they have been infected.
West Nile virus is spread by mosquitoes that breed in areas with standing and stagnant water. Follow the directions on the package. "Wear long sleeve shirts, and trousers if you can".
Keeping window and door screens in good fix. Dunks can be picked up at the Health Department during normal business hours, Monday - Friday, from 8:30 a.m. - 4:30 p.m.
