The cultural, institutional and organizational changes needed in WHO have been clearly set out in the report of the Advisory Group on Reform of WHO’s Work in Outbreaks and Emergencies, a group which I chaired from 2015 - 2016. The changes suggested in this report have been internalized within WHO – and will be progressively reflected in the performance of country, regional and headquarters offices. Implementation has started: it needs to be sustained in a continuous and consistent way with the support of the Independent Oversight and Advisory Committee that will provide recommendation on options for improvement. Over time, as new levels of performance are achieved and benchmarked, credibility and confidence will return, additional funds will be mobilized and WHO’s contribution to outbreak prevention, preparedness and response, as well as in health emergencies, will reach the standard required by Member States.
