Figures above include both confirmed and probable human cases.

An increase in false positive West Nile test results obtained from a national reference lab led to the recall of a test kit that was utilized from July 15, 2008 to September 1, 2008. Possible WNV cases in this period that could not be confirmed through additional tests performed by the CDC or MSDH were removed from the surveillance case count as of January 12. The figures on this page reflect this adjustment.

* Other mosquito-bornes illnesses include LaCrosse encephalitis and Jamestown Canyon virus. LaCrosse encephalitis is a mosquito-borne illness whose symptoms are generally mild with less than one percent mortality. Infants and children can have more severe symptoms, including seizures. Jamestown Canyon infections are similar to West Nile, causing mild fever but leading to encephalitis in some cases.

Eastern equine encephalitis is a mosquito-borne illness that typically affects horses, but human infection can occur, causing serious illness and death.

** Mosquito samples are drawn from mosquito traps statewide. WNV-positive mosquitoes in a sample indicate that WNV is active in the area and could spread to humans.
