First Human Case of West Nile Virus Reported
Dallas County officials on Thursday reported the first positive human case of West Nile virus for this year. The patient was diagnosed with West Nile non-neuroinvasive disease, according to a news release. Officials didn’t identify the individual for privacy reasons but described him as a Dallas resident in his early 40s.
The announcement came several weeks after a report of Tarrant County’s first West Nile virus case of 2025. This is a concerning development, as it indicates that the virus is present in the area and can be transmitted to humans through mosquito bites.
West Nile Virus-Positive Mosquito Pools
As of Thursday, officials said they have found a total of 98 West Nile Virus-positive mosquito pools in Dallas County, with the first one this year being reported in May. This is a significant number, and it highlights the need for people to take precautions to protect themselves against mosquito bites.
There were 37 reported human cases and three deaths for the 2024 season, according to Dallas County health officials. These numbers are a reminder of the potential risks associated with West Nile virus and the importance of taking steps to prevent infection.
How West Nile Virus Spreads
West Nile virus spreads through mosquito bites. When an infected mosquito bites a person, it can transmit the virus, which can then cause a range of symptoms. About 80% of people who catch the virus will not experience symptoms. The remaining 20% will feel fever, fatigue, and nausea, among other ailments. Fewer than 1% of those infected will develop more severe symptoms, which can be fatal.
Prevention is Key
Health officials encourage people to protect themselves against mosquito bites by wearing long sleeves and pants, applying insect repellent, and clearing standing water from their yards and outdoor spaces. These simple steps can help reduce the risk of infection and prevent the spread of West Nile virus.
“With the first West Nile virus human case, it’s an important reminder that prevention is key,” Dr. Philip Huang, director of Dallas County Health and Human Services, said in the news release. By taking precautions and being aware of the risks, people can help protect themselves and their communities from the spread of West Nile virus.
