Progress Toward Regional Measles Elimination - Worldwide, 2000-2020
MMWR. Morbidity and Mortality Weekly Report
|November 10, 2021
Summary
Global measles vaccination efforts saw progress from 2000-2020, with reduced incidence and deaths. However, recent declines in measles-containing vaccine coverage and surveillance sensitivity require intensified action to achieve elimination goals.
Area of Science:
- Public Health
- Epidemiology
- Vaccinology
Background:
- The Global Vaccine Action Plan aimed for measles elimination by 2020.
- Measles-Rubella Strategic Framework and Measles Outbreaks Strategic Response Plan align with Immunization Agenda 2021-2030.
- Robust measles surveillance is crucial for identifying immunity gaps and undervaccination.
Purpose of the Study:
- To report progress on World Health Assembly measles elimination milestones from 2000-2020.
- To analyze trends in measles-containing vaccine coverage and incidence.
- To assess the impact of vaccination on measles mortality.
Main Methods:
- Analysis of global measles surveillance data from 2000-2020.
- Review of measles-containing vaccine (MCV) coverage rates.
- Estimation of measles incidence and mortality trends.
Main Results:
- Estimated MCV first dose coverage increased to 86% in 2019 but fell to 84% in 2020.
- Measles incidence decreased by 88% from 2000-2016, with a rebound in 2019-2020.
- Estimated measles deaths decreased by 94% during 2000-2020, averting 31.7 million deaths.
Conclusions:
- Significant progress has been made in reducing measles incidence and deaths globally.
- Declining vaccination coverage and surveillance sensitivity pose challenges to measles elimination.
- Enhanced efforts are needed to achieve measles elimination targets, focusing on vaccination and surveillance.

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

01:26Principles of Disease Surveillance
234
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...
