4. Large and Disruptive Measles Outbreaks
Notes: Based on data received 2021-09 and covering the period between 2020-08 and 2021-07 - Incidence: Number of cases* / 1M population** - * WHO classifies all suspected
measles cases reported from India as measles clinically compatible if a specimen was not collected as per the algorithm for classification of suspected measles in the WHO VPD
Surveillance Standards. Thus numbers might be different between what WHO reports and what countries report. ** World population prospects, 2019 revision -
In the frame of tracking progress towards the goals of Immunization Agenda 2030 (IA2030), an indicator has been developed by a working group in order to represent
large and disruptive measles outbreaks. This indicator is defined as an incidence equal or greater than 20 reported measles cases per million population over a period
of 12 months. It is important to note that measles outbreak definitions vary between countries and regions according to local context and level of progress towards
regional elimination goals. This definition of large and disruptive outbreaks aims to complement and not replace the national and regional definitions, while also
providing a degree of global standardization and permitting tracking of progress against a common metric.

Notes: Based on data received 2021-09 - Data Source: IVB Database
DRC has experienced a nationwide epidemic that has affected all Provinces, however, only a small proportion of the measles cases in the IDSR aggregate reporting
system are reflected in the case based data. As of 27 May 2013, South Sudan has reassigned to the Africa region (AFR) from the Eastern Mediterranean region
(EMR). For data presentation and statistical purposes, South Sudan data is presented in AFR for all the years.
