Dallas County Mosquito Season Runs From May-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 sometimes a rash.

Although the illness commonly has affected older individuals, even healthy younger people have been sick with West Nile Disease this year. The incubation period for WNV (the period between being bitten by an infected mosquito and showing the first symptoms) varies from 3-15 days.

Anyone who experiences symptoms consistent with WNV 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 County West Nile infections reached epidemic levels.

Because of this, residents are urged to take precautions even in areas where the virus has yet to be detected. County health officials warn the threat of the virus exists in North Texas.
