Health Alert Network (HAN)

CDC Stacks Public Health Publications

The Health Alert Network (HAN) is CDC's primary method of sharing cleared information about urgent public health incidents with public information officers; federal, state, territorial, and local public health practitioners; clinicians; and public health laboratories. CDC’s HAN collaborates with federal, state, territorial, county, and city partners to develop protocols and stakeholder relationships that will ensure a robust interoperable platform for the rapid distribution of public health information. The items in this collection are archived past alerts. For the most up to date information, go to https://www.cdc.gov/han/index.html.
