The three cases were recently confirmed in Livingston Parish and were all asymptomatic, meaning these individuals did not know they were infected, and only found out while donating blood or having blood work.
State Epidemiologist Dr. Raoult Ratard said, "These three infections serve as reminders that West Nile virus is here and all residents are at risk. Everyone should take simple steps to protect themselves, their families and their homes from mosquitoes, which spread West Nile virus to humans when they bite. Protection is as simple as wearing mosquito repellant and covering your skin. You can also prevent mosquitoes from reproducing by dumping standing water from containers around your home."
Health officials characterize West Nile infections three ways: neuroinvasive, West Nile fever and asymptomatic.
A neuroinvasive disease illness is caused by West Nile virus attacking the nerve cells. In older people, it may be very severe and could result in 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.
Last year, Louisiana saw 34 cases of West Nile virus neuroinvasive disease in the state.
Here are some things you can do to protect yourself from West Nile:
- 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.
