West Nile Virus Continues as Primary U.S. Arboviral Threat, CDC Urges Prevention

A CDC report for 2024 shows West Nile virus was the most common arboviral disease in the U.S., causing 1,808 cases and 173 deaths, representing 92% of cases. With an early start to the 2026 season, the CDC emphasizes prevention through insect repellent, protective clothing, and vector control, as no specific treatments or vaccines exist for endemic U.S. arboviruses. This highlights ongoing public health vigilance.
