With just six weeks until the United States, Canada and Mexico host the 2026 FIFA World Cup, Brazil’s Ministry of Health published a technical note on 28 April urging outbound travellers to update their measles immunisations. All three host countries are experiencing active outbreaks—Canada alone has recorded more than 870 cases so far this year after losing its WHO elimination status in 2025. Although Brazil remains free of endemic transmission, the ministry fears imported cases could spark fresh clusters upon fans’ return. The note recommends that adults and children check their vaccination cards at least 15 days before departure and receive an MMR booster if necessary. Airlines and travel agencies will distribute the guidance through IATA’s Timatic database and pre-trip mails. For employers sending sponsorship guests or deploying hospitality staff, the advisory carries both duty-of-care and operational implications. Companies should verify health-insurance coverage for vaccine-preventable diseases and factor in the possibility of quarantine if an employee is exposed abroad. HR teams may also require proof of immunisation before authorising travel reimbursement. The ministry’s alert is part of a broader mobility-health strategy that includes airport fever-screening drills and coordination with CONMEBOL to monitor charter flights. Should the outbreaks worsen, officials have not ruled out recommending yellow-fever style vaccination certificates for boarding—making early compliance the safest course for World Cup-bound Brazilians.
