Health Alert Network (HAN)

The Health Alert Network (HAN) is a Centers for Disease Control (CDC) program set in place to have the public aware of important health information as it becomes relevant and increasing important. The program does stay updated as new information becomes available such as ways to be prepared, a response aspect and help service that works ‘round the clock or 24 hours a day 7 days a week. HAN has a messaging system that covers over 90% of its population and consists of 1,000,000 recipients. The HAN is currently responsible for transmitting health alerts, advisory or warnings and updates on medical updates.


  • Phased into the Public Health Information Network
  • Made up of highly trained medical personnel
  • Base health preparedness off evidence based practices and procedures


The benefits of having the HAN system in place are that it educates the general public under the HAN umbrella about important medical alerts that can have a direct effect with people around you or yourself. If there is a scare, the HAN prepares as much as it can by telling you what the scare is, what location the medical issue is affecting and how to handle it if it does affect you directly.
