LaCrosse Encephalitis Statistics
- LaCrosse encephalitis is found in southeastern Minnesota, especially
in counties along the Mississippi River.
- The first case ever reported was in the early 1960’s in a Houston
County, MN resident. The child died in a LaCrosse, Wisconsin hospital,
and the disease was subsequently named after this city. The Twin Cities
area has been the furthest north and west that LaCrosse encephalitis
virus has been found.
- Similar to other arboviruses, most LaCrosse encephalitis cases occur
later in the summer when infected vector populations are at their highest
level.
