Defense Medical Surveillance System

The Armed Forces Health Surveillance Division (AFHSD) operates the Defense Medical Surveillance System (DMSS), a continuously expanding relational database that documents military and medical experiences of service members throughout their careers. As the central repository of medical surveillance data for the U.S. Armed Forces, DMSS contains up-to-date and historical data on diseases and medical events (e.g., hospitalizations, ambulatory visits, reportable medical events, HIV tests, and casualty data) and longitudinal data on personnel and deployments. AFHSD routinely publishes summaries of notifiable diseases, trends of illnesses of special surveillance interest and field reports describing outbreaks and case occurrences in the Medical Surveillance Monthly Report (MSMR), the principal vehicle for disseminating medical surveillance information of broad interest. Through DMSS, AFHSD provides the sole link between the DOD Serum Repository and other databases.
