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.
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.
