The numbers explain the urgency.
That changes the challenge. Health planning is no longer just about what happens inside a ground. It is about queue management, emergency response, crowd flow and how quickly local systems can react if pressure builds in one part of a host city.
Heat may become one of the defining factors of the tournament, especially in southern venues.
That matters because fans often spend hours in direct sun before kick-off. Hydration, shaded waiting areas and fast medical access could be as important as security checks. For organisers, the challenge is simple: the spectacle cannot outrun the climate.
Other reports in the update say officials are also tracking infectious disease risks closely. Measles appears to be a particular concern, with the CDC reportedly logging nearly 2,000 cases in the US by 21 May this year, while wider research cited in the update puts the broader outbreak total even higher since January 2025. Food safety checks are also said to be increasing around host areas, including restaurants, food trucks and temporary serving sites.
That is the reality of a modern World Cup. The football remains the headline, but logistics, public health and climate planning could shape the fan experience just as much. The next key phase will be how host cities turn these preparations into visible matchday systems before the countdown truly begins.
