Guatemala confirmed a cluster of measles cases linked to a large religious mass gathering in Santiago Atitlán (Dec 2025), with cases detected in multiple departments and an epidemiological alert issued in early Jan 2026. Authorities implemented enhanced surveillance, active case finding, and vaccination response measures.
Measles spread quickly and can be dangerous - protection is simple: get vaccinated!
Swiss recommendations: All persons born after 1963 who have no documented protection against the infection (antibodies or 2 documented vaccinations) should be vaccinated twice with MMR vaccine at one month interval. In the event of an epidemic in the region or contact with a measles case, vaccination is recommended from the age of 6 months.
