West Nile Virus
General Information:
Surveillance for West Nile Virus (WNV) was initiated in Louisiana in the Spring 2000 and currently involves the testing of sick horses and mosquito pools. With the exception of horse testing, WNV testing is performed at the request of individual mosquito abatement districts throughout the state. WNV is considered endemic or native to all parts of Louisiana, thus statewide dead bird reporting has been suspended. Dead bird testing is now understood to be a poor predictor of human cases and its value is limited unless part of a more comprehensive mosquito surveillance program, as is conducted by local or parish mosquito abatement districts.
- Louisiana has four kinds of Encephalitis: West Nile Fever, Saint Louis, Eastern Equine and California Encephalitis.
