La Crosse Encephalitis Statistics

  • La Crosse 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 La Crosse, Wisconsin hospital, and the disease was subsequently named after this city. The Twin Cities area has been the furthest north and west that La Crosse encephalitis virus has been found.

  • Similar to other arboviruses, most La Crosse encephalitis cases occur later in the summer when infected vector populations are at their highest level.
