LOCS Message Level Types
CDC’s Laboratory Outreach Communication System provides recipients with three types of messages: alerts, advisories, and updates. See the LOCS message types below to learn more information.

Provides important information for a specific incident or situation; contains recommendations or actionable items to be performed by public health officials, laboratory professionals, and/or clinicians; may not require immediate action.
Provides updated information regarding an incident or situation, or provides non-incident information such as laboratory-related resources and partner news; unlikely to require immediate action.
