Measles outbreaks in the Americas: PAHO calls for strengthened vaccination and surveillance


The Pan American Health Organization (PAHO) has issued an epidemiological alert due to an increase in measles cases in several countries in the Americas. As of epidemiological week 8 of 2025 (21 February 2025), 268 measles cases, including one death, have been confirmed in Argentina, Canada, Mexico, and the United States. This represents a significant increase compared to the same period in 2024, when 60 cases were reported during the first eight weeks of the year.
