ASTHO helps state and territorial public health agencies prevent and control infectious diseases and associated outbreaks through immunization services, infectious disease prevention programs, surveillance, and outbreak response. Additionally, ASTHO seeks to advance health equity in infectious disease prevention and control through programmatic and policy work.
