Measles Threat Looms Over the Americas Ahead of 2026 World Cup
A surge in measles cases across the Americas is raising concerns as the region prepares to host the 2026 FIFA World Cup. The Pan American Health Organization (PAHO) issued an epidemiological alert this week, urging countries to bolster surveillance, vaccination efforts, and rapid response mechanisms to prevent further transmission.
Canada Loses Measles-Free Status, US and Mexico at Risk
The alert follows Canada’s loss of its measles-free status in November. The United States and Mexico are now facing a similar risk, having requested a two-month extension to contain their respective outbreaks. The situation is further complicated by the United States’ withdrawal from the World Health Organization (WHO) in January, the parent agency of PAHO.
Dramatic Increase in Cases
In the first three weeks of 2026, PAHO confirmed 1,031 new measles cases in seven countries – a 43-fold increase compared to the same period last year. While no deaths have been reported to date, the concentration of cases remains high. Mexico currently leads with 740 cases, followed by the United States with 171 and Canada with 67.
Global Resurgence and Vaccination Gaps
This PAHO alert comes after a year of continuous growth in measles cases – the largest increase in five years – driven by a global resurgence and what the agency describes as “persistent gaps in immunization.” Approximately 78% of recent cases have involved individuals who were not vaccinated.
Vulnerable Populations
While adolescents and young adults account for the majority of cases, the highest incidence rates are among children under one year old. This disparity underscores the critical require to strengthen coverage of the second vaccine dose.
World Cup Concerns and Vaccination Rates
With the 23rd edition of the FIFA World Cup approaching, regional data is alarming. Currently, only 33% of countries in the Americas have achieved the 95% threshold for the first dose of the measles vaccine, and a mere 20% have reached it for the second dose. The tournament, hosted across Canada, Mexico, and the United States from June 11th to July 19th, is expected to draw massive crowds, potentially exacerbating the spread of the virus.
Global Measles Trends
The WHO warned in November that, despite an 88% reduction in measles deaths worldwide since 2000 thanks to vaccination, cases are increasing. In 2024, approximately 11 million cases were reported globally. Fifty-nine countries reported large or disruptive measles outbreaks in 2024, nearly triple the number recorded in 2021 and the highest since the start of the COVID-19 pandemic.
