Heading to the FIFA World Cup? Here’s how to stay healthy in a crowd

The buzz this summer is all about the FIFA World Cup soccer games. As New Jersey welcomes fans from around the globe, here are a few tips to help you stay healthy in crowded stadiums, on public transportation and at your local watch parties.   

“International events like this bring people together from many regions, increasing exposure to illnesses that aren’t typically in the local community,” says Jason Kessler, MD, an infectious disease specialist at Atlantic Health. “Most people will enjoy the games without any issues, but large gatherings do create conditions where infectious diseases spread easily.” 

Dr. Kessler shares five simple ways to stay healthy while you enjoy the excitement of live sports. 

1. Make sure your vaccinations are up to date 

Before attending the World Cup events, check that you're current on recommended vaccines. Measles, flu and COVID-19 spread easily in crowded environments, so pay particular attention to these vaccines:  

• Measles (MMR vaccine) 
• Seasonal influenza (flu vaccine) 
• COVID-19 vaccines and boosters 
• Tdap (tetanus, diphtheria and pertussis) 

2. Don't forget basic hand hygiene 

Thousands of people are touching railings, seats and door handles. Even high-fives create opportunities for germs to spread.  

Bringing along a small bottle of hand sanitizer is a good idea. And when soap and water are available, washing your hands is still the most effective way to reduce the spread of illness – especially before meals and after touching public surfaces. 

3. Protect yourself from heat and sun 

Dr. Kessler says that heat can pose a greater risk to fans than an infectious disease. That’s because outdoor stadium events expose you to prolonged heat and sun. To avoid dehydration and heat exhaustion, here are a few important reminders: 

• Drink water consistently throughout the day. 
• Limit excessive alcohol consumption. 
• Wear sunscreen and reapply as directed. 
• Consider lightweight, sun-protective clothing, hats and sunglasses. 
• Sit in shady spots whenever possible. 

4. Be smart about your food choices 

Food vendors at major events serve thousands of meals each day. While most food is prepared safely, pay attention to the food quality and temperature, and don't hesitate to discard anything that seems questionable. 

If you choose meat, poultry or seafood, make sure it’s thoroughly cooked. Undercooked food can increase the risk of foodborne illnesses.  

5. Know when it’s better to stay home 

No one wants to miss a World Cup match. But if you’re feeling lousy, attending an event can put you and others at risk. 

“Consider staying home if you have a fever, chills, respiratory symptoms or severe fatigue,” says Dr. Kessler. “Hot weather, long walks, crowded venues and limited access to medical care can make things worse. So, trust your instincts. If you don't feel right, it’s best to watch the match from home.” 

Who should take extra precautions? 

Dr. Kessler cautions that some people are at a higher risk for heat exposure and infectious diseases. If you’re in any of these groups, it’s worth talking with your doctor before attending the event: 

• Adults age 65 and older 
• People with weakened immune systems 
• Pregnant individuals 
• Those with chronic heart or lung disease 

“It’s also important to be aware of your surroundings,” says Dr. Kessler. “Know where emergency exits are, and report anything that seems unusual. With a little preparation and awareness, you can stay focused on the excitement of the games.”
