Typically, LaCrosse encephalitis initially presents as a nonspecific illness with fever, headache, nausea, vomiting, and lethargy. Severe cases occur most commonly in children under the age of 16, the elderly, and those with reduced or compromised immune systems. These severe cases can produce seizures, coma, paralysis, and a variety of neurological complications after recovery.
