MEMPHIS, TN - Health authorities say they've confirmed a fourth victim of the West Nile virus in Shelby County this year.
That brings to eight the number of cases of the mosquito-born disease reported across Tennessee in 2007.
The latest Shelby County victim, who was not identified by name, contracted the virus in October and has made a full recovery, health department officials said Monday.
The virus, which also can infect birds and other animals, usually leads to mind symptoms in human victims that include fevers, headaches and body aches.
Rare, extreme cases, however, can lead to high fever, disorientation and even death.
While colder weather has moved into Tennessee, health authorities point out that mosquitoes will still be around until the first frost.
