Louisiana Department of Health and Hospitals reports 20 cases of West Nile so far this year

(WAFB) -

The Louisiana Department of Health and Hospitals (DHH) confirmed Wednesday a total of 20 cases statewide of West Nile virus so far this summer. Of the 20 cases this year, 10 have been neuroinvasive disease (NID), two have been West Nile fever and eight have been asymptomatic.

"It’s critical for adults and children to wear mosquito repellent at all times while outdoors," said State Health Officer Dr. Jimmy Guidry. "Whether your children are playing sports, your family is outside grilling or you’re doing yard work, be sure to protect yourself and your family."

About 90 percent of all West Nile virus cases are asymptomatic, while about 10 percent will develop West Nile fever. Only a very small number of infected individuals will show the serious symptoms associated with NID. Residents who are at least 65 years old are at higher risk for complications, but everyone is at risk for infection.

Protecting Yourself

  • If you will be outside, you should wear a mosquito repellent containing DEET. The American Academy of Pediatrics (AAP) recommends that repellents should contain no more than 30 percent DEET when used on children. Insect repellents also are not recommended for children younger than 2 months. CDC recommends that you always follow the recommendations appearing on the product label when using repellent.
  • Apply repellent on exposed skin and clothing. Do not apply under your clothes or on broken skin.
  • To apply repellent to your face, spray on your hands and then rub on your face.
  • Adults should always apply repellent to children.
  • Wear long-sleeved shirts and pants when outdoors for long periods of time.
  • Avoid perfumes and colognes when outdoors for extended periods of time.
  • Make sure that your house has tight-fitting windows and doors, and that all screens are free of holes.  

Protecting Your Home

  • Reduce the mosquito population by eliminating standing water around your home, which is where mosquitoes breed.
  • Dispose of tin cans, ceramic pots and other unnecessary containers that have accumulated on your property. Turn over wheelbarrows, plastic wading pools, buckets, trash cans, children's toys or anything that could collect water.
  • Drill holes in the bottom of outdoor recycling containers. Drainage holes that are located on the container sides collect enough water for mosquitoes to breed.
  • Check and clean roof gutters routinely. They are often overlooked, but can produce millions of mosquitoes each season.
  • Aerate ornamental pools or stock them with fish. Water gardens can become major mosquito producers if they are allowed to stagnate.
  • Clean and chlorinate swimming pools that are not being used. A swimming pool that is left untended by a family for a month can produce enough mosquitoes to result in neighborhood-wide complaints. Be aware that mosquitoes may even breed in the water that collects on swimming pool covers.  

Last year, Louisiana saw 61 cases of West Nile virus neuroinvasive disease in the state. DHH has been tracking West Nile Virus for more than a decade, and statistics about its occurrence in Louisiana can be found online at www.dhh.louisiana.gov/fightthebite.

Travel Precautions

Anyone traveling abroad should also take these same precautions to protect themselves from mosquitoes in other countries. Mosquitoes in other parts of the world, including the Caribbean, South America, Asia, Africa and Europe, might infect you with chikungunya or dengue fever.
