Colombia on High Alert for Measles Outbreak Amid World Cup Risks

Colombian health authorities are increasing vaccination efforts and monitoring potential measles outbreaks as the country prepares for the 2026 World Cup. The alert follows a rise in global infections and the identification of suspected cases linked to international travel.

On February 27, 2026, Colombian health officials confirmed that four individuals with a history of international travel were under observation for possible measles infections. While laboratory testing has since ruled out one of these cases, three remain under analysis as epidemiological experts review clinical details to confirm or rule out the presence of the virus.

The concern is intensified by the upcoming 2026 World Cup, which begins on June 11, 2026, across the United States, Canada, and Mexico. The tournament is the first to feature teams from 48 different countries and is expected to host millions of spectators across 104 events in 16 cities over a 39-day period.

Public health analysts at BlueDot have noted that mass gathering events involving massive global travel are moments of great risk. Significant ticket sales have been recorded from Brazil, Colombia, and Argentina, countries that BlueDot describes as having serious and varied infectious disease burdens.

According to BlueDot, the risk is further compounded by the status of the host nations and several European countries, which have either recently lost measles elimination status or are endemic. The organization reported a significant trend of measles outbreaks in South America, where vaccination coverage is generally lower.

Regional and Global Measles Trends

The World Health Organization reported that 247,623 measles cases were confirmed in 179 countries in 2025. In the Region of the Americas, 14,891 cases were reported during 2025, representing a 32-fold increase compared to the figures from 2024.

Earlier data from the World Health Organization indicated that between January 1 and April 18, 2025, 2,318 measles cases, including three deaths, were confirmed in six countries within the Americas. This represented an 11-fold increase over the same period in 2024.

• Canada: 1,069 cases
• United States of America: 800 cases (including two deaths)
• Mexico: 421 cases (including one death)
• Argentina: 21 cases
• Brazil: 5 cases
• Belize: 2 cases

The World Health Organization assessed the regional risk as high as of April 18, 2025, noting that ongoing virus circulation from imported cases has led to outbreaks with extended transmission chains and the spread of the virus to new areas.

The organization highlighted that the majority of these cases occurred among people between 1 and 29 years of age who were either unvaccinated or had an unknown vaccination status. While measles is preventable with two doses of the vaccine, the World Health Organization reported that over 22 million children worldwide did not receive their first dose in 2023.

Local Impact and Preventative Measures

In Colombia, Bogotá is currently preparing for the possibility of an epidemic. In contrast, the city of Ibagué reported that it had not registered any cases of measles as of April 11, 2026.

Health experts are calling for reinforced vaccination campaigns to prevent a mass outbreak. This proactive response is viewed as a necessary investment in the safety of athletes, fans, and local communities across North America during the World Cup.

The U.S. Embassy in Bogotá previously issued a health alert on June 18, 2025, stating that measles is an ongoing risk worldwide and that an increasing number of international travelers are becoming infected.

Colombian authorities view the resurgence of the virus in North America and other regions with concern, particularly as the country prepares for the mobilization of millions of travelers for the upcoming tournament.
