The Louisiana Department of Health and Hospitals confirmed Friday 11 new cases of West Nile virus, including one death in Lafourche Parish.
The man who died, lived in Larose and family members say he was in his 80's.
The new cases bring this year's total in Louisiana to 103 reported infections.
This week's new infections include seven neuroinvasive disease cases in Ascension (1), Lafourche (3), Point Coupee (1), Terrebonne (1) and Washington (1) parishes.
There were two new cases of West Nile Fever, one in Jefferson Davis parish and the other in Livingston parish; and two new asymptomatic cases, one in East Baton Rouge parish and the other in Ascension parish.
"Temperatures are starting to drop in parts of the state, but the start of fall weather shouldn't change how you protect yourself from mosquito bites outside," said DHH State Epidemiologist Dr. Raoult Ratard.
"Remember that you can protect yourself by wearing long sleeves and pants when outside, using mosquito repellent and avoiding the outdoors during dawn and dusk when mosquitoes are the most active."
About 90% of all cases are asymptomatic, while about 10% will develop West Nile fever. Only a very small number of infected individuals will show the serious symptoms associated with the neuroinvasive disease.
