The Louisiana Department of Health and Hospitals is reporting four new West Nile cases this week.  That brings this year's total number of cases to 13.  

Two of the new infections were the most serious neuroinvasive disease.  Both of those were reported in Ouachita parish.  There were also two asymptomatic cases, one each in Ouachita and Vernon Parishes.

Humans contract West Nile when they're bitten by mosquitoes infected with the virus. For this reason, state health officials caution Louisiana residents to do everything possible to protect themselves from mosquitoes when they're outdoors and to take steps to eliminate mosquitoes around their homes and businesses
