Human Case of West Nile in Iberia Parish

There's a human case of west nile virus in Iberia Parish. It's one of two new cases in the state, which brings this year's total to 25. The other is in St. Tammany Parish.

The Louisiana Department of Health and Hospitals characterize West Nile infections three ways: neuroinvasive, West Nile fever and asymptomatic. A neuroinvasive illness is severe and typically results in a swelling of the brain or spinal cord. People with this illness are at risk of brain damage or death. West Nile fever is less severe, with most people only suffering mild, flu-like symptoms. Asymptomatic individuals were never ill and were only discovered to have the West Nile virus in their blood when blood work was done for some other reason, such as blood donation. Both new cases reported were neuroinvasive disease.

This year, West Nile Virus in Louisiana is most prevalent in East Baton Rouge and Ascension parishes, with 12 cases and nine cases respectively. East Baton Rouge has had seven cases of the more serious neuroinvasive disease, one case of West Nile Fever and four asymptomatic cases.

Ascension Parish has had one case of neuroinvasive disease, five cases of West Nile Fever and three asymptomatic cases. Red River, Livingston, Iberia and St. Tammany parishes each have one case of neuroinvasive disease. No deaths have been attributed to West Nile this year.

To avoid being bitten by mosquitoes, residents can take the following precautions:

    * If you will be outside, you should wear a mosquito repellent containing 20 - 30 percent DEET for adults and no more than 10 percent for children.

    * 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.

Residents can also help control the mosquito population by eliminating standing water around their home, which is where mosquitoes breed. Louisianians are encouraged to follow these tips:

    * Dispose of tin cans, ceramic pots and other unnecessary containers that have accumulated on your property. Turn over wheelbarrows, plastic wading pools or buckets 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.

    * Clean clogged roof gutters yearly. 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 that goes on vacation 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.
