Summary:What is already known about this topic? Humans become infected by arboviruses primarily through the bite of an infected mosquito or tick. West Nile virus is the leading cause of arboviral disease in the continental United States. What is added by this report? Despite fewer total arboviral disease cases in 2022 compared with 2021, historically high numbers of St. Louis encephalitis and Powassan virus disease cases were reported. What are the implications for public health practice? The variable occurrence of arboviral diseases highlights the importance of surveillance efforts in targeting prevention messaging and control. Health care providers should consider arboviral testing for patients with clinically compatible illnesses. Prevention depends on reducing vector populations, implementing personal protective measures to decrease exposure, and screening blood and tissue donors.
