Table 2. Risk matrix.

Likelihood Consequences
Minimal Minor Moderate Major Severe
Note: Actions and response framework (based on WHO guidelines): L (Low risk): Managed according to standard response protocols, routine control programmes, and regulation (e.g., monitoring through routine surveillance systems). M (Moderate risk): Roles and responsibilities for the response must be specified; specific monitoring or control measures are required (e.g., enhanced surveillance). H (High risk): Senior management attention is needed; there may be a need to establish command and control structures; a range of additional control measures will be required, some of which may have significant consequences. VH (Very high risk): Immediate response is required even if the event is reported out of normal working hours; immediate senior management attention is needed (e.g., establishing command structures within hours); the implementation of control measures with serious consequences is highly likely.
