Dallas County reports 2024's first West Nile death

The big picture: The virus is the most common mosquito-borne disease in the continental United States, though it isn't as prevalent as other illnesses. Thousands of cases are reported each year, per the Centers for Disease Control.

Zoom in: The Dallas patient lived in the 75230 ZIP code, which includes North Dallas, per Dallas County Health and Human Services.

• She had underlying health conditions and was diagnosed with West Nile neuroinvasive disease, a more serious infection affecting less than 1% of people who contract the virus.

Threat level: The virus can be spread to humans through the bite of an infected mosquito. It isn't spread through casual contact, like touching or kissing, the CDC says.

• Dallas, Harris and four other counties reported 23% of U.S. cases from 2009–2018.
• About 20% develop flu-like symptoms.

What they're doing: Counties typically spray areas where mosquito samplings test positive for the virus.

What to do: Wear insect repellents containing DEET and cover exposed skin with long, loose and light-colored clothing.

• Eliminate standing water near home and work.
• Limit outdoor activities between dawn and dusk.
