LaCrosse encephalitis
Pathogen
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.
Distribution
Vector – Aedes triseriatus
Found primarily east of the Rocky Mountains in North America, Aedes triseriatus is considered a vector of several types of encephalitis. Adults fly mostly during the early morning and evening hours, but they can be easily disturbed during daylight hours and are persistent biters.
Larval Habitat
Deciduous tree holes
