SP 5: Outbreaks & Emergencies
5.1

Outbreak detection and response

What Does this Indicator Measure?

The indicator measures the proportion of polio, measles, meningococcal disease, yellow fever, cholera, and Ebola outbreaks with timely detection and response. The indicator includes only outbreaks with an outbreak response vaccination campaign. This indicator ensures preparation for, detection of, and rapid, high-quality responses to vaccine preventable disease outbreaks.

How Will Progress be Measured?

Progress will be measured by the time of onset of an outbreak to the implementation of a vaccination campaign. The maximum time for the period from onset of outbreak to implementation of vaccination campaign to be considered timely will be defined for each vaccine. Criteria for determining onset of outbreak and timeliness of outbreak detection and response to be consistent with WHO surveillance standards and disease eradication, elimination, or control strategies.

Definition: Proportion of polio, measles, meningococcal disease, yellow fever, cholera, and Ebola outbreaks* with timely** detection and response

Ebola: 51 days from 1st case onset of symptoms to start of response vaccination campaign

Yellow Fever: 86 days from 1st case onset of symptoms to start of response vaccination campaign.

Wild Poliovirus: 63 days from 1st case onset of paralysis to start of response vaccination campaign.

Circulating Vaccine Derived Poliovirus: 63 days from 1st case onset of paralysis to start of response vaccination campaign.

Mesales (non-endemic): 69 days from 1st case onset of symptoms to start of response vaccination campaign.

Measles (endemic): 35 days from when incidence crosses epidemic threshold to start of response vaccination campaign.

Meningococcus: 27 days from when incidence crosses epidemic threshold to start of response vaccination campaign.

Cholera: 27 days from when incidence crosses epidemic threshold to start of response vaccination campaign.

Measurement approach: Information from the International Coordinating Group on vaccine provision, Measles Rubella Initiative, Global Polio Eradication Initiative, and WHO World Health Emergencies group, supplemented by national immunization and disease surveillance programs via the WHO/UNICEF Joint Reporting Form. Over the next few years, additional pathogens may be added to the scope of SP 5.1 in alignment with global vaccine-preventable disease eradication, elimination and control goals, particularly as additional outbreak-prone diseases become vaccine-preventable.
Calculation: Calculation of indicator will involve division of collective total number of known polio, measles, meningococcal disease, yellow fever, cholera, and Ebola outbreaks with timely detection and outbreak response vaccination campaigns by collective total number of known polio, measles, meningococcal disease, yellow fever, cholera, and Ebola outbreaks with outbreak response vaccination campaigns.
Data source: ICG, MRI, GPEI, WHO, national immunization and disease surveillance programs. Information will be systematically collected from national immunization and disease surveillance programs to provide data for regional and global level data.

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.
