  • Estimating the basic reproduction number of measles in low-and middle-income settings using 172 seroprevalence studies

    Open AccessHan Fu, Alyssa N Sbarra et al.ARTICLEPLOS Global Public Health2026

    The basic reproduction number, R 0 , is an epidemiological measure to describe the transmissibility of infectious diseases and evaluate the potential effect of interventions. Measles R 0 has historically been considered to be between 12–18, with contextual factors contributing to its heterogeneity, but has rarely been estimated using data across multiple countries. Our study aims to estimate measles R 0 in low- and middle-income countries using a…
