Mississippi State Department of Health (MSDH) reports six new human cases of West Nile virus (WNV) for 2008, bringing the state’s total number of WNV cases to 15. The new cases are in Clarke, Harrison, Lawrence, Monroe (2) and Neshoba counties. The MSDH reports both confirmed and probable cases to the public. The Board of Animal Health has also notified MSDH of three additional cases of Eastern Equine Encephalitis (EEE) in horses in George County.

To date, the state’s total number of mosquito-borne illnesses is 15 human cases of WNV, three human cases of LaCrosse Encephalitis (LAC) and four cases of Eastern Equine Encephalitis (EEE) in horses.

Since March 2008, WNV cases have been reported in Clarke, Forrest, Harrison, Hinds, Jones (3), Lawrence, Lincoln, Madison (2), Monroe (2), Neshoba and Pearl River counties. Three cases of LAC have been reported in Adams, Hinds and Yazoo counties.

The MSDH conducts statewide mosquito testing with its most intensive surveillance during the peak WNV mosquito reproduction months of July, August and September. To date, one group of collected mosquitoes has tested positive for WNV in Jones County. A positive test result indicates local mosquitoes are infected with WNV and are capable of transmitting it to humans and other hosts.

MSDH encourages Mississippians to take the following simple precautions to reduce their risk of contracting West Nile virus, LaCrosse encephalitis, and other mosquito-borne illnesses:

* Remove sources of standing water

* Avoid mosquito-prone areas, especially between dusk and dawn when mosquito activity is highest

* Wear protective clothing (such as long-sleeved shirts and pants) when in mosquito-prone areas

* Apply a mosquito repellent according to the manufacturer's instructions
