This report lays out 12 recommendations to ensure the adequate financing of the capabilities and infrastructure required to prevent, identify, contain, and respond to infectious disease outbreaks. Many countries chronically underinvest in critical public health functions like disease surveillance, diagnostic laboratories, and emergency operations centers, which enable the early identification and containment of outbreaks. So far, 37 countries have completed the rigorous peer-reviewed assessments, called the Joint External Evaluation (JEE), of their preparedness capacities to identify their gaps and needs. But that leaves 162 countries that have not. Moreover, only two of the countries that have completed this assessment have used the results to devise costed plans. The report urges national governments to prioritize financing preparedness in their domestic budgets, as should international donors.
