Measles and Rubella Global Update April 2024 Distribution List

Measles and Rubella Global Update April 2024

Distribution list This report is distributed by email on a monthly basis. To join the distribution list, please send an email to Sebastien Antoni (antonis@who.int)

Disclaimer Please note that all data contained within is provisional. The number of cases of measles and rubella officially reported by a member state is only available by July of each year (through the joint WHO UNICEF annual data collection exercise). If any numbers from this provisional data are quoted, they should be properly sourced with a date (i.e. "provisional data based on monthly data reported to WHO (Geneva) as of April 2024"). For official data from 1980-2023, please visit our website.

Data sources and limitations The Global Measles and Rubella Report is based on surveillance data reported by Member States to the regional offices weekly or monthly. The regional compilation is reported to HQ monthly. Data are to be reported from the regions on the 1stFriday of the month, and HQ attempts to release the monthly report by the 3rdMonday of the month. Please note:  Numbers of cases might differ from the official numbers reported annually as part of the WHO/UNICEF Joint reporting process (JRF). The difference can be due to the time lag as the annual data might not be complete at the time of reporting.  In addition, the difference can be due to multiple surveillance systems at country level. In these cases, the monthly data are extracted from the case based surveillance system while the annual data can be from the aggregated system. Epidemiologic Data: Case-based and/or Aggregate Reporting to WHO  Epidemiologic data comes from Member States in one of two forms  Case-based data, which is our recommendation, is provided by most member states. At WHO HQ, we collect a limited set of variables, including, age, date of onset, country reporting, 1st/2nd administrative unit of residence, vaccination status (by recall), date related to specimen collection/testing, and final classification. Regions might or might not collect more data than this. Often suspected cases with recent date of onset are not classified; however, at HQ we classify pending cases as clinically compatible and update the data if/when new data are provided to HQ. For AFR, we classify all cases that are rubella IgM+ as rubella laboratory-confirmed cases.  Aggregated data on number of suspected, lab-confirmed, epi-linked, and clinically compatible cases of measles/rubella, by month/year of onset, and by subnational area (though some member states do not provide this level of disaggregation).  Source for zero-reporting from some member-states though this is not a consistent process.  A few member states send us both case-based and aggregated data as they have two different surveillance systems in the country.  If both aggregate and case-based data are sent to HQ, numbers from aggregate surveillance are considered case counts for the country, while case-based data are used for the national slides to show age distribution, proportion vaccinated, and age-specific incidence. ELISA Laboratory Data from the Global Measles and Rubella Laboratory Network (GMRLN) • The Global Measles Rubella Laboratory Network laboratories report the number of samples received as well as the number of samples tested for IgM serology, as well as the number positive, negative and equivocal. • These aggregated data are collected to account for the inadequate linking between laboratory and epidemiological data in some countries. • Numbers of cases reported may differ from the number of samples tested positive for various reasons • Samples tested positive in a laboratory may not reported to the surveillance system • IgG screening results are inappropriately included in the surveillance database • Inconsistent reporting from laboratories. • This is based on the number of SAMPLES tested, not the number of CASES tested. One case can have multiple samples being tested (e.g. different specimen types, repeat specimen collection based on timing of collection). Limitations • Data are only from network laboratories • Non-network laboratories are not included • Some laboratories don’t report • IgG results are sometimes inappropriately reported Limitations • Reporting delays: It can take 2-3 months from the time a case is reported to public health in a member state to the time the data are provided to WHO HQ. • Some of this is due to normal reporting delays that are expected as it takes time to get information from a health center to Geneva based on reporting frequencies set by various levels • We are working to decrease the delays in reporting. • Underreporting/lack of reporting • Case definitions for suspect, epidemiologically linked and clinically compatible cases may vary between countries. • Completeness of the data reported to WHO is unknown • For this monthly update, pending cases are considered measles clinically compatible. • These cases may later be discarded or confirmed based on laboratory testing in which case historical case counts may vary from one report to another. • This could lead to differences between the Global monthly report and Regional or National surveillance bulletins published by WHO Offices and National authorities. Genotyping Data Genotyping data are obtained from the MeaNS2 (https://who-gmrln.org/means2) and RubeNS2 (https://who- gmrln.org/rubens2). Limitations • Inadequate sample collection for genotyping challenges interpretation of the data • Underreporting • WHO recommends that Member States submit genotyping data to these databases, but it is not currently a requirement so there is underreporting • Genotype data can’t be linked to epidemiologic data at the global level

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 2024-04 and covering the period between 2022-12 and 2023-11 - Incidence: Number of cases / 1M population - Population Data: World population prospects, 2019 revision - A high proportion of clinical cases indicates a high level of uncertainty associated with the incidence rates and the inclusion of countries in this list.

Disclaimer This document contains data provided to WHO by member states. Note that some member states only provide aggregate data to WHO, and for these, we are unable to generate a country profile. Some member states report all cases at one time point for the entire year, and thus epidemiologic curves generated are not accurate and a reporting artifact. For some countries, cases are reported by age category, not by exact age in months and/or years. Thus, age distribution/incidence is approximate. Cases classified as pending by countries are classified at WHO as clinically compatible at this time, and thus numbers might different between data shown here and provided by the member state or WHO country/regional offices. *UN population data is used as the denominator for calculating incidence.
