Which browser best supports HSE?


Internet Explorer is the recommended browser, but ultimately this depends on your organization’s browser settings. Historically, CAC-enabled sites function reliably in Internet Explorer. Given security parameters, this application can also be viewed in Google Chrome.


What if the application does not load correctly?


If the application doesn’t load correctly (grey screen, missing tools, etc.), follow these steps:

What content appears on the HSE?


AFHSB analysts and senior leaders determine what disease and health events appear on the portal. The HSE contains health surveillance information from a variety of AFHSB products in its role to provide timely, relevant, actionable, and comprehensive health surveillance information in order to promote, maintain, and enhance the health of the military and its associated populations. In addition, the health and disease events can be viewed in proximity to U.S. Embassy locations, the AFHSB’s Global Emerging Infections Surveillance (GEIS) section’s partner network of Department of Defense service laboratories and global military treatment facilities. All content on the site is archived and can be searched for historical context. AFHSB is continuing to explore additional Force Health Protection related content for the HSE.


How can users request additional information about an event on HSE?


There are multiple ways to get more information about an event. Each event on the main screen map has a Request for Information (RFI) button to allow users to directly email AFHSB’s Alert and Response Operations staff. You can also tap on the information button at top left of the main screen map. n the header at the top of main screen map.


How are the health and disease event threat levels for the HSE determined


Each disease or health event is assessed as a ROUTINE, MODERATE, or HIGH public health threat. For a detailed explanation of the event threat levels, users can click on the Legends widget at the top right corner of the header bar on the main map screen for a brief explanation of each threat level.

All levels are determined by AFHSB based on the implementation of Force Health Protection (FHP) countermeasures. For more information, select the “How Are These Thresholds Determined” link at the bottom of the Legends widget screen.


Can the content on the portal be shared?


All content on the HSE portal is For Official Use Only (FOUO)/Not for Public Release, and should be treated as controlled unclassified information. Some material is FOUO/Department of Defense (DOD) Use Only and should not be shared outside of DOD. If there is information that you wish to disseminate further, please contact AFHSB.


Can the content on the portal be shared?


This product is built using a deployment of ESRI’s ArcGIS Enterprise—specifically, the Portal for ArcGIS. It is a full-featured mapping and analytics platform that includes a powerful GIS server plus a dedicated web-based GIS infrastructure to organize and share work.


Why is the HSE hosted on a National Geospatial-Intelligence web address?


The National Geospatial-Intelligence Agency (NGA) delivers world-class geospatial intelligence that provides a decisive advantage to policymakers, warfighters, intelligence professionals, and first responders. It is the world leader in timely, relevant, accurate, and actionable Geospatial Intelligence (GEOINT). NGA enables the U.S. intelligence community and the Department of Defense to fulfill the President’s national security priorities to protect the nation. The Armed Forces Health Surveillance Branch (AFHSB) operates under the Defense Health Agency as part of its role as a Combat Support Agency providing sound epidemiological data to improve the health and readiness of all service members and associated populations.
