West Nile Related Deaths

Last week, county health officials confirmed the tenth human case of West Nile Virus in Dallas County this year. The patient is a resident of Irving and has been diagnosed with West Nile Fever illness. The announcement comes shortly after DCHHS confirmed the first WNV death of the year. For medical confidentiality and personal privacy reasons, DCHHS does not provide additional identifying information.

“Controlling an epidemic of WNV infection is a community effort that calls upon residents to take preventative measures to reduce exposure,” said Ganesh Shivaramaiyer, DCHHS interim director. “Dallas County Health and Human Services not only conducts active surveillance to detect WNV and monitor infection rates locally but also educates the community to take preventative action.”

This season, mosquito samples have tested positive for WNV in the cities of Addison, Balch Springs, Carrollton, Cedar Hill, Coppell, Dallas, Desoto, Duncanville, Farmers Branch, Garland, Glenn Heights, Highland Park, Irving, Mesquite, Richardson, Rowlett, Sachse, Seagoville and University Park.

Mosquito Season Runs Through End of October

West Nile Virus (WNV) is a preventable condition. Humans commonly get West Nile Virus by being bitten by infected mosquitoes. Mosquito season in Dallas County typically runs from May to October with peak activity in August. Residents should be on heightened alert during these months of the dangers of West Nile Virus.

WNV is one of a group of viruses spread by mosquito bites. The most severe type of West Nile Virus is sometimes called “neuroinvasive disease” because it affects a person’s nervous system. Specific types of neuroinvasive disease include: West Nile Encephalitis, West Nile Meningitis or West Nile Meningoencephalitis.

West Nile Fever is another type of illness that can occur in people who become infected with the virus. Symptoms of West Nile virus in humans may include fever, headache, tiredness, muscle aches, confusion, stiff neck, nausea and rash.

Although the illness commonly has affected older individuals, even healthy younger are susceptible. The incubation period for WNV (the period between being bitten and showing the first symptoms) varies from 3-15 days.

Anyone who experiences WNV symptoms should see a physician as soon as possible. Health officials are still urging the public to take protective measures in preventing the illness. In Dallas Co. West Nile infections reached epidemic levels.
