A critical component of laboratory surveillance for measles is the genetic characterization of circulating wild-type viruses. The World Health Organization (WHO) Measles and Rubella Laboratory Network (LabNet), provides for standardized testing in 183 countries and supports genetic characterization of currently circulating strains of measles viruses. The goal of this report is to describe the lessons learned from nearly 20 years of virologic surveillance for measles, to describe the global databases for measles sequences, and to provide regional updates about measles genotypes detected by recent surveillance activities. Virologic surveillance for measles is now well established in all of the WHO regions, and most countries have conducted at least some baseline surveillance. The WHO Global Genotype Database contains >7000 genotype reports, and the Measles Nucleotide Surveillance (MeaNS) contains >4000 entries. This sequence information has proven to be extremely useful for tracking global transmission patterns and for documenting the interruption of transmission in some countries. The future challenges will be to develop quality control programs for molecular methods and to continue to expand virologic surveillance activities in all regions.

Measles (rubeola) cases and outbreaks have increased worldwide in 2023 and 2024. This article provides a comprehensive overview of the global resurgence of measles cases, highlighting the critical role of vaccination in preventing outbreaks. It also discusses the factors contributing to declining vaccination rates, the implications for public health, and immediate infection control measures in the event of suspected cases.

Vaccination against measles-mumps-rubella and rates of non-targeted infectious disease hospitalisations: Nationwide register-based cohort studies in Denmark, Finland, Norway, and Sweden.

J Infect

January 2025

Bandim Health Project, Research Unit OPEN, Department of Clinical Research, University of Southern Denmark, Odense C, Denmark; Department of Clinical Epidemiology, Aarhus University Hospital, Aarhus, Denmark.

Objectives: To investigate if receipt of measles-mumps-rubella (MMR) vaccine following the third dose of diphtheria-tetanus-acellular pertussis (DTaP3) is associated with reduced rates of non-targeted infectious disease hospitalisations.

Methods: Register based cohort study following 1,397,027 children born in Denmark, Finland, Norway, and Sweden until 2 years of age. Rates of infectious disease hospitalisations with minimum one overnight stay according to time-varying vaccination status were compared using Cox proportional hazards regression analysis with age as the underlying timescale and including multiple covariates.

Centre for Immunization Surveillance and Programs, Infectious Disease and Vaccine Program Branch, Public Health Agency of Canada, 130 Colonnade Rd S, Nepean, ON K1A0K9, Canada; Department of Pediatrics, Faculty of Medicine, McGill University. Electronic address:

Background: In susceptible individuals, post-exposure prophylaxis (PEP) is often recommended following exposure to measles, however the data that these recommendations are based on are limited. The objective of this systematic review was to evaluate the efficacy/effectiveness and safety of immunoglobulins (Ig) or measles-containing vaccine (MCV) for the prevention of measles.

Methods: Prospective studies evaluating the use of Ig or MCV as PEP in susceptible individuals exposed to measles were eligible for inclusion.

The objective of this study is to gain insight into the current research frontiers, hotspots, and development trends in the field of immunization programs for women and children, and to provide scientific guidance and reference for follow-up research. Based on all the original research papers related to the research on immunization programs for women and children in the Web of Science Core Collection (WoSCC) database, bibliometric studies and visual analysis were carried out to explore the research frontiers, hotspots and development trends, and to analyze the risk factors affecting the vaccination coverage of immunization programs for women and children. Eight hundred forty-three papers obtained from 1,552 institutions in 96 countries/regions from January 1950 to August 2024, coauthored by 4,343 authors.

Background/objectives: Spain has been in a measles elimination phase since 2014. No evidence exists about the distribution of measles cases among the population born outside Spain. The aim of this study was thus to describe the epidemiological situation of measles, stratified by place of birth, during the post-elimination period in Spain.
