Public health officials have confirmed the state’s first case of the West Nile virus of 2023 in Dallas.
Dallas County Health and Human Services reported that a resident has been diagnosed with West Nile neuroinvasive disease.
West Nile virus is transmitted through the bite of infected mosquitoes. Most people exposed to the virus don’t get sick, but about 20% develop symptoms like headache, fever, muscle and joint aches, nausea and fatigue. In a very small proportion, less than one percent, the virus affects the nervous system, leading to the more serious West Nile neuroinvasive disease that can cause neck stiffness, disorientation, tremors, convulsions, paralysis and even death.
“It’s important for people to be aware that there are many diseases transmitted by mosquitoes found in Texas,” said DSHS Commissioner Jennifer Shuford, MD, MPH. “Most of these diseases cause mild illness but in rare instances, diseases like dengue or Zika can cause severe illness. We’ve even had a locally acquired case of malaria in Texas this year, which underscores the importance of taking precautions to prevent mosquito bites.
