When the FIFA World Cup 2026 kicks off on June 11, the world’s attention will be fixed on goals, players, and outcomes on the field. But behind every match is an invisible factor that can determine whether athletes perform at their peak—and whether fans stay healthy. That factor is environmental hygiene.

Mass gatherings on the scale of the World Cup bring millions of people into close contact across shared spaces, creating known risks for infectious disease outbreaks. Among the most persistent threats is norovirus, a highly contagious gastrointestinal illness with a documented history at large international sporting events.

Dr. Gavin Macgregor-Skinner, senior director at ISSA, said the scope of the 2026 tournament alone demands heightened attention.

“The FIFA World Cup 2026 begins on June 11, 2026—48 national teams, 104 matches, over 5 million spectators in 16 stadiums across the United States, Canada, and Mexico,” Macgregor-Skinner said. “But grasp at this—those people have to stay somewhere.”

He explained that teams, staff, and fans will move through hotels, airports, training facilities, transportation hubs, and public venues far beyond stadium walls. From a cleaning and public health perspective, every one of those environments matters.

“These are the best of the best coming to our country,” Macgregor-Skinner said. “They depend on us having controlled environments that support their respiratory function, neurologic processing, hydration, recovery—all the things that allow them to stay at the top of their game.”

Macgregor-Skinner emphasized that cleaning in this context is not simply housekeeping—it is public health infrastructure. He pointed to past outbreaks tied to major sporting events, including the postponement of a hockey game at the 2006 Winter Olympics due to norovirus, as well as documented gastrointestinal illness outbreaks at FIFA tournaments in Germany, Japan, and Qatar.

Norovirus, he said, presents unique challenges.

“It can last on hard surfaces, soft surfaces, and laundry for up to two weeks and remain infectious,” Macgregor-Skinner said. “You can’t clean the way you normally clean. You have to clean and disinfect in a very special way to inactivate or destroy the virus.”

Dr. Rebecca Bascom, a medical doctor with Penn State, underscored the importance of coordinated preparation across the entire value chain.

“My alert would be: Let’s take this on as a community,” Dr. Bascom said. “The people that make the cleaning chemicals, the people that distribute them, the facility managers, the cleaning professionals—we all need to come together so we have best practices and are prepared to respond to an outbreak and restore safety.”

One of the most common misconceptions, both experts said, involves hand hygiene. Alcohol-based hand sanitizers, while useful for many pathogens, are not effective against norovirus.

“The CDC states that for norovirus, you must wash hands well with soap and water,” Macgregor-Skinner said. “Alcohol-based hand sanitizer alone does not work.”

Proper handwashing, he explained, requires time, friction, soap, and water—not a quick squirt while heading to a match.

As the tournament approaches, Macgregor-Skinner stressed that visible cleaning alone is not enough.

“Visible cleaning is not evidence,” he said. “Cleaning without measurement is guessing.”

He pointed to CDC-recommended, risk-based environmental hygiene strategies that include ventilation, targeted surface disinfection, and testing to verify cleanliness. Many of the tools exist, he said, including the EPA’s List G of disinfectants proven effective against norovirus. The challenge now is education and training.

“This is not assumed knowledge,” Macgregor-Skinner said. “This is learned knowledge—and there’s a lot of training to be done before June 11.”

For the cleaning industry and public health professionals alike, the message is clear: protecting performance and public health at the World Cup begins long before the opening kickoff.
