 The LAC virus is one of many mosquito-transmitted viruses that can cause an inflammation of the brain (encephalitis). About 80-100 cases of this condition are reported each year in the United States. Most cases occur in children younger than age 16. While most people who become infected have no symptoms, those who do become ill may have fever, headache, vomiting and lethargy (tiredness). Severe cases develop encephalitis accompanied by seizures. Coma and paralysis occur in some cases. There is no specific treatment for LAC encephalitis. Supportive therapy is provided to those who develop severe cases of the disease.La Crosse (LAC) encephalitis is a mosquito-borne virus that was first described in La Crosse, Wisconsin in 1963. Since then, it has been reported in several Midwestern and Mid-Atlantic states.
