🟠 Moderate Evidence
The Pan American Health Organization has issued urgent recommendations to strengthen measles surveillance and vaccination programmes as countries prepare to host the 2026 FIFA World Cup. The guidance comes amid concerns about potential disease transmission during large international gatherings, where millions of visitors from diverse vaccination backgrounds will converge.
Key takeaways
- PAHO recommends enhanced measles surveillance for all 2026 World Cup host countries
- Mass gatherings pose elevated risks for vaccine-preventable disease outbreaks
- Vaccination coverage verification and catch-up campaigns are essential preparatory measures

PAHO Issues Comprehensive Prevention Guidelines
The Pan American Health Organization released detailed recommendations on June 2, 2026, emphasising the critical importance of robust measles prevention measures. Dr. Jarbas Barbosa, PAHO Director, highlighted the organisation’s commitment to preventing vaccine-preventable disease outbreaks during the tournament.
The guidance specifically targets the United States, Canada, and Mexico as co-host nations, along with participating countries sending teams and supporters. Global health experts have long recognised mass sporting events as potential amplification points for infectious disease transmission.
Enhanced Surveillance Systems Required
PAHO’s recommendations centre on strengthening existing measles surveillance infrastructure well before the tournament begins. The organization emphasises the need for real-time reporting systems and rapid response capabilities to detect and contain potential outbreaks.
Countries must ensure healthcare workers can quickly identify measles symptoms and implement appropriate isolation measures. The World Health Organization defines measles as one of the most contagious viral diseases, with the potential for rapid spread in unvaccinated populations.
Vaccination Coverage Verification Essential
The PAHO guidance stresses the importance of verifying vaccination coverage rates across all age groups, particularly among young adults who may have missed routine immunisations. Countries should implement catch-up vaccination campaigns targeting vulnerable populations and international travellers.
Healthcare systems must prepare for increased demand for vaccination services as the tournament approaches. The CDC recommends that international travellers ensure they are up to date with measles-mumps-rubella (MMR) vaccination before travel.
Mass gathering events require heightened vigilance for vaccine-preventable diseases, with measles posing particular risks due to its high transmissibility and potential for rapid spread among susceptible populations.

What this means
Frequently asked questions
Why is measles surveillance particularly important for the World Cup?
Large international gatherings bring together people from countries with varying vaccination coverage rates. Measles is highly contagious and can spread rapidly in crowds, making early detection and response critical.
What vaccination requirements should travellers expect?
While specific requirements will be announced by host countries, PAHO recommends all international travellers verify their measles immunity through vaccination records or antibody testing.
How effective are measles vaccines in preventing outbreaks?
The MMR vaccine is highly effective, providing approximately 97% protection after two doses. Population immunity levels above 95% typically prevent sustained measles transmission.
The success of PAHO’s recommendations will depend on coordinated implementation across all participating countries and robust international cooperation. Public health preparedness for major international events requires months of advance planning and sustained commitment from healthcare systems. As the 2026 World Cup approaches, the effectiveness of these preventive measures will be crucial in ensuring both sporting success and public health protection.
