August 01, 2014 DHH Confirms Six New West Nile Virus CasesHealth Officials Urge Residents to "Fight the Bite"

- The Louisiana Department of Health (DHH) is confirming six new West Nile virus cases this week, bringing this year's total number of cases to 15. This week's new infections include three cases of neuroinvasive disease in Caddo Parish, two cases of West Nile fever, with one each in Caddo and Livingston parishes, and an asymptomatic case in East Baton Rouge Parish. This week's cases can be found in the weekly West Nile virus Surveillance report by clicking here

"If you're going outside, protect yourself," said State Epidemiologist Dr. Raoult Ratard. "If mosquitoes are biting, everyone is at risk. We recommend you take the necessary precautions to protect yourself and your children. We encourage everyone to control the mosquito population by dumping standing water from containers around their home. This prevents mosquitoes from reproducing."

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 is down from 2002's high of 204 cases of West Nile virus neuroinvasive disease. 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.
