July 17, 2015 DHH Asks Residents to Take Precautions Against MosquitoesHealth Department Confirms Three New Cases of West Nile

Baton Rouge, La., Jul 17, 2015 - The Louisiana Department of Health (DHH) has confirmed three new cases of West Nile virus this week, the first cases of 2015. This week's new infections include two cases of neuroinvasive disease, one in LDH Region 2 and one in Region 6. The third case, also in Region 6 was asymptomatic.

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 the neuroinvasive disease. Residents who are at least 65 years old are at higher risk for complications, but everyone is at risk for infection.

"There is an opportunity for you to get bitten every time you step outside, whether you're taking a quick walk to the mailbox or spending hours at the ball park," said State Health Officer Dr. Jimmy Guidry. "You need to take the proper steps to protect yourself and your home from mosquitoes every time you go outdoors."

Last year, Louisiana saw 61 cases of West Nile virus neuroinvasive disease in the state. LDH 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.

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% 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.  

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.
