In 2016, WHO Member States voted at the World Health Assembly to establish the WHO Health Emergencies Programme (WHE), strengthening WHO’s central role in the global health emergencies’ architecture, including in relation to risk assessment.
WHO subsequently developed a standardized methodology for risk assessments, based on the Rapid Risk Assessment of Acute Public Health Events manual. To attain the highest possible level of objectivity, accuracy and reproducibility, the standardized RRA approach is applied by those conducting public health intelligence activities at WHO. This approach is used regardless of the source or origin of the public health risk or event.
The RRA approach applied by WHO is a systematic, continuous, collaborative and reiterative process of gathering and documenting information and characterizing the risk posed by a public health risk or event at national, regional and global levels. It shapes WHO’s advice on public health actions to manage and mitigate the impact of public health risks and events, including to prevent their international spread. The RRA approach is applied to large scale events that already or could potentially exceed the capacity of the country(ies)/territory(ies) facing the event to respond; to public health risks or events with actual or potential international implications; and to those requiring WHO operational support.
