As the countdown to the 2026 FIFA World Cup in North America begins, football fans are already planning flights, booking hotels, and mapping out itineraries across Canada, Mexico, and the United States. However, health authorities are issuing a critical reminder that the most important part of any travel itinerary isn’t a ticket or a passport—it is a completed vaccination record.
Health officials in Medellín, alongside global health agencies, are urging travelers to ensure they are vaccinated against measles before departing. The push comes amid a global resurgence of the virus, which thrives in high-density environments like international sporting events. Because measles is one of the most contagious diseases known to medicine, a single infected traveler can inadvertently spark a localized outbreak, threatening both the traveler and the communities they visit.
For those residing in Medellín, the city’s health infrastructure is already pivoting to meet this need. The Secretaría de Salud has launched targeted vaccination drives to ensure that not only the fans heading north are protected, but that the city’s own tourism frontline is fortified against imported cases.
Why Measles is a Major Concern for Global Travelers
From a clinical perspective, measles is far more than a childhood ailment. It is a highly aggressive respiratory virus that spreads through the air via droplets and aerosolized particles. It can remain suspended in the air or live on surfaces for up to two hours after an infected person has left the room.
The danger lies in its efficiency. In an unvaccinated population, one person with measles can infect as many as 12 to 18 others. In the context of a World Cup—where thousands of people from different continents congregate in stadiums, fan zones, and public transit—the potential for rapid transmission is significant.
Rita Almanza, the leader of Epidemiology at the Medellín Health Secretariat, has emphasized the urgency of preventative action. “If you plan to travel to countries with active measles cases or attend international events, such as the upcoming World Cup, we recommend visiting any of the city’s vaccination points to request the vaccine,” Almanza stated.
Fortifying Medellín’s Tourism Frontline
Medellín’s strategy is two-fold: protecting those leaving the city and shielding those who welcome the world. The Health Secretariat recognizes that tourism workers are the primary point of contact for international arrivals, making them “sentinels” who could either stop or facilitate the spread of the virus.
To mitigate this risk, the city has prioritized vaccination for specific professional groups, including:
- Transportation workers: Specifically taxi and rideshare drivers who move visitors across the city.
- Hospitality staff: Personnel working in hotels, and hostels.
- Entertainment and Leisure: Employees at tourist attractions and nightlife venues.
- Tour Operators: Guides who lead groups through the city’s landmarks.
Geographically, the city is concentrating its efforts in high-traffic areas. Comuna 13, one of the city’s most visited international corridors, has become a focal point for mobile vaccination clinics and educational campaigns. By creating “pockets of immunity” in these high-density zones, health officials hope to prevent the city from becoming a hub for transmission.
Recognizing the Symptoms and Taking Action
Because measles can initially mimic a common cold or flu, early detection is often missed. For travelers and residents alike, recognizing the progression of the illness is vital for containment.
| Stage | Common Symptoms | Recommended Action |
|---|---|---|
| Early Phase | High fever, cough, runny nose, red eyes | Isolate and monitor temperature |
| Progression | Small white spots (Koplik spots) inside cheeks | Immediate medical consultation |
| Peak Phase | Pinkish-red rash starting at face/neck, spreading downward | Strict isolation; notify health authorities |
Health authorities have issued a strict directive: any individual presenting with a fever and a skin rash must refrain from attending work or participating in tourist activities. Immediate consultation with health services is required to prevent further community spread.
A Global Effort in a Post-Pandemic World
The push in Medellín mirrors a broader global trend. In recent years, vaccination rates for the MMR (Measles, Mumps, and Rubella) vaccine have dipped in several regions due to pandemic-related disruptions in routine healthcare and a rise in vaccine hesitancy.
This gap in “herd immunity” has left populations vulnerable. When people travel from regions with low vaccination rates to areas with similar gaps, the result is often a spike in cases. By applying over 23,900 doses between January and April in recent drives, Medellín is attempting to close these gaps before the massive influx of travel associated with the 2026 tournament.
For those unsure of their vaccination status, medical professionals recommend a “better safe than sorry” approach. Receiving an additional dose of the MMR vaccine is generally safe and provides the necessary peace of mind for international travel.

As the World Cup approaches, the Secretaría de Salud will continue to monitor global epidemiological trends and update its local vaccination strategy. The next phase of the city’s campaign will involve expanding mobile clinics into additional tourist corridors to ensure maximum coverage before the peak travel seasons.
