The West Nile virus, a mosquito-borne illness, is spreading across the United States with alarming speed, now reported in 38 states. The Centers for Disease Control and Prevention (CDC) recently updated their list, revealing the widespread nature of the virus this year. Among those affected is Dr. Anthony Fauci, who described his experience as the worst illness he's ever endured. "I've never been as sick in my life," Fauci told STAT, adding that while he's on the mend, it will take weeks to recover fully. This virus has the potential to cause severe neurological issues, and it's not just limited to a few states—it's a nationwide concern. Here, Best Life breaks down where the virus is most prevalent, highlighting the states with the highest number of cases. From Texas, which leads the nation with 46 reported cases, to Connecticut, where only one case has been recorded, we’ll provide a comprehensive overview of the situation. You’ll also learn about the symptoms to watch out for, why some states are particularly vulnerable, and what experts like Dr. Fauci recommend for protecting yourself and your loved ones from this dangerous virus.

Two cases have been confirmed in Arkansas. "If a mosquito bites you to take a blood meal and they do have a virus, then they can inject that into you," said Dr. Laura Rothfeldt with the Arkansas Department of Health to THV11. "A very, very small portion of those persons who do become ill could become even worse and could have an infection around their brain that causes some neurological issues," Rothfeldt said.

Arizona is a breeding ground because of all the standing water. “Mosquitoes lay eggs in standing water, and they only need enough water to fill a bottle cap, said Loretta Schraeder, the manager of pest control at Bill’s Pest and Termite Control,” according to AZ Central. “Regularly removing and drying any water in your yard is the best way to prevent mosquitoes from breeding there, Schraeder said.”
California

frantic00 / ShutterstockTo stay safe from West Nile virus, it's important to take proactive steps to protect yourself and your family. Use insect repellent containing DEET, picaridin, or oil of lemon eucalyptus when spending time outdoors, especially during dawn and dusk when mosquitoes are most active. Wear long sleeves, pants, and socks to reduce exposed skin, and consider using mosquito netting in areas with high mosquito activity. Eliminating standing water around your home, such as in flower pots, gutters, and birdbaths, can help reduce mosquito breeding sites. Keeping doors and windows screened can also prevent mosquitoes from entering your home. By following these precautions, you can significantly lower your risk of contracting West Nile virus and other mosquito-borne illnesses.
