Montana Health Alert Network 

CDC HAN Website

Montana's Health Alert Network (HAN) promotes the sustainable development of modern Internet-based data communications capacities in a manner that will support the emerging Public Health Information Network (PHIN) architecture. These capacities include Internet and e-mail access for Local County Health Departments and Tribal Health Agencies. Building an Internet-based tele-communications infrastructure to advance the rapid dissemination of information between the Department of Public Health and Human Services (DPHHS) and Local County Health Departments, Indian Health Services and Tribal Health Agencies. Thus improving disease surveillance, and supporting Public Health Worker training in association with Public Health Emergency Preparedness (PHEP) and the public health workforce development efforts associated with the Public Health Improvement Task Force.

The Department of Public Health and Human Service’s (DPHHS) Emergency Notification System sent out the following Health Alert Network messages to Local County Health Departments, Tribal Health Agencies and to their respective health partners in Montana. The HAN messages contain vital public health information that either originated at the Center for Disease Control and Prevention (CDC), DPHHS or at the local level.  DPHHS routinely forwards this information on to all of the local health jurisdictions in Montana when it is determined that the information could potentially affect residents in Montana.
