Health Surveillance Explorer

In 2019, The Armed Forces Health Surveillance Division created an innovative application that makes it more efficient and effective to assemble, integrate, and display health surveillance data. The Health Surveillance Explorer is a dynamic CAC-enabled mapping application that allows Geographic Combatant Commands to identify health threats and disease outbreaks worldwide in near real-time. And that helps GCCs protect the health and readiness of their forces wherever they may be deployed worldwide. Learn more about the HSE by watching the HSE Intro Video. (3 minutes, 15 seconds)
