Reduce large or disruptive vaccine-preventable disease outbreaks

What Does this Indicator Measure?

This indicator measures the number of large or disruptive outbreaks of six vaccine-preventable diseases (VPDs): cholera, Ebola, measles, meningococcus, wild poliovirus (WPV) and circulating vaccine-derived poliovirus (cVDPV), and yellow fever.

How Will Progress be Measured?

By 2030, fewer large or disruptive outbreaks are expected to occur compared to the baseline. Given the dynamic nature of outbreaks, and the expected fluctuation of outbreaks across the decade, the trendline will be monitored. The target is a declining trend in the global annual number of large or disruptive outbreaks for each VPD. Progress will be evaluated annually.

Definition: Outbreak threshold criteria for large or disruptive VPD outbreaks are:

Cholera: In highly endemic countries, a threshold increase in the annual number of reported cases compared to the average annual incidence over the past 5 years. Or for countries that are endemic-epidemic, over 12,000 cases reported annually.

Ebola: >50 cases.

Measles: Incidence equal to or greater than 20 reported measles cases per million population over a period of 12 months.

Meningococcus: A cumulative attack rate >100 suspected meningitis cases per 100,000 population within one year in a given population based on a definition used for the African meningitis belt. Each region will set its own definitions for epidemics/outbreaks and targets for reduction according to local epidemiology.

Polio - wild poliovirus (WPV): > 1 WPV from any source (e.g., cases, environmental surveillance, contacts, healthy children's samples) in a country per year AND confirmation of local circulation in accordance with the standard operating procedures for outbreak response.

Polio - circulating vaccine-derived poliovirus (cVDPV): > 1 cVDPV from any source (e.g., cases, environmental surveillance, contacts, healthy children's samples) in a country per year AND evidence of local circulation in accordance with the standard operating procedures for outbreak response.

Yellow fever: 5 cases in endemic areas. Or >1 cases in an area previously without yellow fever.
Measurement approach: Large or disruptive VPD outbreaks are identified using data collected by the International Coordinating Group for Vaccine Provision, WHO Headquarters and WHO Regional Offices with technical assistance from VPD control, elimination, and eradication initiatives. For multi-country outbreaks, each country’s portion of the outbreak was assessed separately.
Calculation: The directionality of the trend will be measured by calculating the line of best fit for the data points (number of annual large or disruptive outbreaks) over time (from baseline to 2030) assessing its slope.
Data source: VPD eradication, elimination, and control programmes and the WHO World Health Emergencies surveillance systems

The IA2030 Scorecard visualizes the monitoring and evaluation indicators of the IA2030 Framework for Action endorsed in 2020 by the World Health Assembly, with the support of countries and partners. The scorecard is a collaborative effort led by MOMENTUM Country and Global Leadership working in partnership with the IA2030 Working Groups on Monitoring & Evaluation and Communications & Advocacy, with oversight from the IA2030 Secretariat and Coordinating Committee.
