Mexico’s Measles Outbreak: A Looming Threat Ahead of the World Cup
Mexico is battling a concerning measles outbreak, with 9,187 confirmed cases since the start of 2025. The federal government is urging unvaccinated citizens to get vaccinated, emphasizing that measles is “the most contagious viral disease.” This surge in cases raises significant public health concerns, particularly as Mexico prepares to co-host the 2026 FIFA World Cup.
The Rising Case Numbers and Regional Hotspots
Almost 30% of the confirmed cases – 2,755 – have been recorded in 2026 alone, with a disproportionate impact on infants and young children. As of February 11, 2026, Mexico’s measles death toll stands at 28, with two fatalities reported in the first six weeks of this year. Jalisco is currently the epicenter of the outbreak, accounting for 58% of the national total in 2026, with 1,603 confirmed cases. Chiapas, Mexico City, and Sinaloa too report significant numbers of cases: 282, 157, and 144 respectively.
On a per capita basis, Jalisco has the highest incidence, with 17.85 confirmed cases per 100,000 people. Colima, Chiapas, and Sinaloa follow with rates of 7.65, 4.56, and 4.49 per 100,000, respectively. While most states have reported cases, Baja California Sur, Tamaulipas, Campeche, Zacatecas, and Coahuila have, so far in 2026, reported no confirmed cases, though probable cases have been detected.
Vaccination Efforts and Government Response
The Mexican government is taking steps to address the outbreak, with Deputy Health Minister Ramiro López Elizalde stating that 28 million doses of the measles vaccine are “ready to apply immediately,” in addition to the 14.3 million doses already administered in 2025 and 2026. Vaccination efforts are prioritizing children aged six months to 12 years, with a focus on ensuring complete vaccination schedules. For those aged 13 to 49 who are unvaccinated or have only received one dose, vaccination is now available in Jalisco, Colima, Chiapas, Sinaloa, Nayarit, Tabasco, and Mexico City.
A new platform, dondemevacuno.salud.gob.mx, has been launched to help citizens locate vaccination centers. Health Minister David Kershenobich emphasized that 90% of measles cases in Mexico occur in unvaccinated individuals, highlighting the effectiveness of the vaccination strategy.
The Risk to Mexico’s Measles-Free Status and the World Cup
Mexico’s decades-long measles-free status is now at risk. The Pan American Health Organization (PAHO) is scheduled to review data on April 13, 2026, to determine whether to revoke Mexico’s status. Experts suggest Mexico has already effectively lost this status, and the PAHO review will be a formal declaration.
This potential loss of status coincides with Mexico’s role as a co-host of the 2026 FIFA World Cup, expected to attract up to 5 million international travelers. Experts warn that unvaccinated visitors could exacerbate the outbreak, creating a significant public health challenge. Victoria Pando Robles, an infectious-disease researcher, noted the potential for “exponential” growth in cases if susceptible individuals gather in large crowds, such as at World Cup stadiums.
Looking Ahead: Maintaining Immunity and Preventing Further Spread
The current situation underscores the importance of maintaining high vaccination coverage to prevent the re-establishment of measles in Mexico. Continued vaccination campaigns, particularly targeting vulnerable populations and those with incomplete vaccination records, are crucial. Public health officials are also considering measures to encourage vaccination among travelers entering Mexico for the World Cup.
