Washington Health Alert Network

The Washington Health Alert Network (WA HAN) is an alert distribution system run by the Washington State Department of Health (DOH). WA HAN messages focus on advisories and updates that are current, actionable, and relevant to public health in Washington state. They are intended for public health partners such as local health jurisdictions (LHJs) and tribal health partners.

There are three levels for WA HAN messages:

  • Health Alert: High level of alert. Alerts may require immediate action or contain urgent information.
  • Health Advisory: Standard level of alert. Advisories are important, but they may not require immediate action.
  • Health Update: Non-urgent messages. Updates may include information about ongoing outbreaks or any level of Centers for Disease Control and Prevention (CDC) Health Alert Network (HAN) message that is not directly relevant to Washington.

We send WA HAN messages to our public health audiences in three ways:

  • Posted on this webpage
  • Sent to public health partners through email subscription
  • Urgent/alert-level messages might also be sent by email, phone, or text alert on the WA SECURES platform
