Each outbreak is assigned one of three standardized threat levels based on the following objective criteria:
Confirmed, ongoing local transmission among the general population. New cases reported within the last 14 days with evidence of sustained community spread.
Examples: Active dengue season, ongoing Ebola cluster, confirmed Mpox community transmission.
Imported cases with no evidence of onward community transmission, OR a limited outbreak within a closed cohort (hospital, refugee camp) with active containment measures.
Examples: Single imported H5N1 case under monitoring, hospital cholera cluster, subsiding measles school outbreak.
Seasonal endemic activity at or above historical baseline, OR a previously Active/Watch outbreak where new cases have not been confirmed in 14–30 days but the surveillance period is not yet closed.
Examples: West Nile virus season without acute cluster, plague in endemic region without current outbreak.
