The Nebraska Department of Health and Human Services (NDHHS) operates the Health Alert Network (HAN), a crucial system for distributing timely public health information and strengthening emergency preparedness across local, state, and federal levels.

This nationwide network shares vital updates on public health incidents and prevention/treatment guidelines. It reaches a broad audience including health care providers, hospitals, laboratories, pharmacies, veterinarians, dentists, long-term care facilities, Tribal health centers, and local health departments via email and text messages.

HAN communications are categorized into three levels: Health Alert, requiring immediate action; Health Advisory, providing important information without necessarily needing immediate action; and Health Update, offering updated information unlikely to require immediate action.
