The Pan American Health Organization has published a guide with health recommendations for travellers and pilgrims ahead of Pope Leo XIV's visit to Argentina, Uruguay, and Peru from 6 to 17 November. The advisory comes as measles cases in the Americas reached 57,666 confirmed cases between January and 31 October 2026.
Why it matters
The guidance is aimed at reducing measles transmission during travel and mass gatherings, which can bring large crowds together across borders. Health authorities are focusing on prevention as case counts in the region have risen sharply compared with the previous year.
Confirmed measles counts in the Americas reached 57,666 cases and 81 deaths from January to October 2026, a figure 4.7 times the same period in 2025. The extraction does not say which countries drove the rise or whether cases are linked to the papal itinerary.
