The World Cup's summer schedule coincides with high temperatures in several host cities, increasing the risk of heat-related illnesses, particularly for those consuming alcohol. Infectious diseases, including measles and flu, are also a concern, with unvaccinated individuals at higher risk. Crowded stadiums and fan zones may lead to physical injuries such as sprains and fractures, while the emotional stress of matches could trigger cardiac events in vulnerable individuals. Groups at higher risk include older adults, pregnant individuals, and those with chronic or immunocompromised conditions. Awareness and preparation are critical to mitigating these risks.
