evidence: Measles virus is one of the most infectious pathogenic agents and has a basic reproduction number (R0) of 12–18, indicating that each infected person could infect 12–18 other susceptible persons (1). In 2022, measles caused an estimated 136,000 deaths globally and predominantly affected unvaccinated persons and undervaccinated children <5 years of age (1). Despite the number of deaths, measles vaccination has averted an estimated 57 million deaths in the 22 years since 2000 (1). Because of exclusive interhuman transmission, the existence of an effective and safe live attenuated vaccine, and the absence of healthy carriers, measles is inherently an eradicable disease. By 2023, a total of 82 countries had achieved measles elimination through high immunization coverage (2).
