Given the increase in measles cases in the Americas Region during 2025 and 2026, the occurrence of other public health events in countries within and outside the Region, and in the context of large-scale events with broad international participation, the Pan American Health Organization / World Health Organization (PAHO/WHO) urges Member States to prioritize the strengthening of surveillance and vaccination activities and to ensure a rapid and effective response to suspected measles cases. PAHO/WHO also recommends implementing active community, institutional, and laboratory-based case-finding for early case identification, as well as conducting supplementary vaccination activities aimed at closing immunity gaps.
