SHREVEPORT, LA (KSLA) - According to the the Louisiana Department of Health and Hospitals (DHH), a second person has died from West Nile virus and 14 new cases have been reported this week. Several of those new cases are in Northwest Louisiana.
The individual who died from the virus is older than 75, however, the person's identity and the area where the person lived have not been released. This year's total number of West Nile cases is now at 29.
Louisiana health officials say a Caddo Parish resident was the first to die from the West Nile virus in 2014. The individual was between 60 and 74 years old.
DHH issues a weekly Arbovirus Surveillance Report that details cases detected thus far by parish. This week's new infections include neuroinvasive disease cases in Caddo (3), East Baton Rouge (2), Ascension (1) and Livingston (1) parishes. There were also new cases of West Nile fever reported from Caddo (3), Bossier (1) and Tangipahoa (1) parishes, and asymptomatic cases in Caddo (1) and Livingston (1) parishes. This week's cases can be found in the weekly West Nile virus Surveillance report by clicking here.
"The increased cases we are seeing this year are a firm reminder that West Nile Virus is a serious disease, and people need to be vigilant about protecting themselves," said Dr. Raoult Ratard, DHH State Epidemiologist. "We know from more than 10 years of surveillance that this disease is active in every corner of the state, and people are at risk of getting it regardless of whether cases or deaths occurred in their parishes. Everyone should take precautions against mosquito bites."
Humans contract West Nile when they are bitten by mosquitoes infected with the virus. When people are infected with West Nile, the virus will affect them one of three ways. West Nile neuroinvasive disease is the most serious type, infecting the brain and spinal cord. Neuroinvasive disease can lead to death, paralysis and brain damage. The milder viral infection is West Nile fever, in which people experience flu-like symptoms. The majority of people who contract West Nile will be asymptomatic, which means they show no symptoms. These cases are typically detected through blood donations or in the course of other routine medical tests.
About 90 percent of all 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 65 years old and older are at higher risk for complications, but everyone is at risk for infection.
Last year, Louisiana saw 34 cases of West Nile virus neuroinvasive disease in the state, which was down from 2002's high of 204 cases of West Nile virus neuroinvasive disease. 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.
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 of age. 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, avoiding your eyes. 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. Chikungunya Fever/Dengue Fever
DHH continues to monitor chikungunya fever and dengue fever, and include any reported cases in its weekly Arbovirus Surveillance Summary. This week, DHH is reporting two new imported cases of chikungunya, bringing this year's total to eight. DHH has an existing case of dengue fever. All of the state's chikungunya and dengue fever infections took place while the individuals were visiting other countries.
