Medical Electronic Disease Surveillance Intelligence System (MEDSIS)



The Medical Electronic Disease Surveillance Intelligence System (MEDSIS) is a secure web-based, centralized, person-based disease surveillance system for Arizona. MEDSIS is a statewide system hosted and supported by the Arizona Department of Health Services (ADHS) for use by local health departments for disease surveillance, and for individuals and institutions responsible for reporting communicable diseases. It is a secure system that is designed to ensure that patient information is kept confidential. MEDSIS is also used for communicating case information with health officials in Sonora, Mexico, regarding cases of bi-national interest.
