Definition: Proportion of polio, measles, meningococcal disease, yellow fever, cholera, and Ebola outbreaks* with timely detection and response**
- Numerator: Number of known polio, measles, meningococcus, yellow fever, cholera, and Ebola outbreaks with an outbreak response vaccination campaign with timely detection and response*
- Denominator: Number of known polio, measles, meningococcus, yellow fever, cholera, and Ebola outbreaks with an outbreak response vaccination campaign
**Definitions for timely detection and response vary by disease and are consistent with WHO VPD surveillance standards, International Coordinating Group (ICG) on Vaccine Provision performance standards, and disease eradication, elimination, or control strategies’ outbreak response standards.
- 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.
- Measles (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.
Method of estimation:
Step 1) Across all WHO Member States, calculate the total number of outbreaks for each pathogen which required a vaccination response.
Step 2) Of those, calculate the number of outbreaks with timely detection and response.
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.
