Historical summaries are provided for horse, human, mosquito
and bird positive samples dating back to 1978 and are displayed by year and by parish.
Note:
Not all parishes conduct arbovirus surveillance using sentinel chickens, wild
birds, and/or mosquitoes. In parishes that have horse and human cases only,
arbovirus transmission between birds and mosquitoes may be occurring naturally but will not be detected due
to the lack of surveillance. Also, arbovirus surveillance strategies change
periodically, such as whether or not to test mosquito pools. Horse and
mosquito information before 1993 is limited and the totals reported in this
pages may not accurately reflect arbovirus transmission in those years or
parishes.
