First case of LAC reported
The Mississippi State Department of Health reports the first human case of LaCrosse encephalitis (LAC) for 2010 in Montgomery County. The case was reported in a child. LAC is a mosquito-borne illness similar to West Nile virus (WNV).
LAC virus cases are occasionally reported in Mississippi, with the most recent case being reported in 2008. The illness is generally mild with less than one percent mortality. Infants and children infected with LAC usually have more severe symptoms than adults. Those infected with LAC often have no symptoms, but some may experience fever, headache, vomiting, lethargy and sometimes seizures.
