Will the World Cup Put the U.S. at Risk of Disease?

As millions prepare to descend upon the United States for the FIFA World Cup, health experts are expressing concerns about the nation’s vulnerability to infectious diseases. The tournament, set to take place across 11 cities from June 11 for a duration of 39 days, is expected to draw significant crowds, raising alarms over the potential for health emergencies.

The U.S. is currently facing challenges in its public health leadership, which exacerbates the concerns surrounding these upcoming mass gatherings. The Centers for Disease Control and Prevention (CDC) is without a permanent director following the dismissal of Dr. Susan Monarez last year. There is also uncertainty surrounding the position of deputy director, which remains vacant. Meanwhile, Dr. Jay Bhattacharya from the National Institutes of Health has been temporarily filling the leadership void, but is set to step down due to legal constraints on serving in the role.

In addition to these leadership gaps, the U.S. has taken steps that have raised eyebrows within the global health community. The nation has withdrawn from the World Health Organization (WHO) and significantly reduced funding for international health initiatives. Recent appointments, including one controversial choice to lead the U.S. response to a hantavirus outbreak, have also come under scrutiny.

Experts warn that the World Cup poses a unique opportunity for the transmission of infectious diseases due to the high volume of international visitors. Jennifer Nuzzo, a professor at Brown University School of Public Health, highlighted the risks associated with large gatherings of people, especially those coming from diverse regions of the world. “When you have a lot of people coming from all over the world gathering for extended periods of time, that is really ripe for health emergencies,” she stated.

Potential health threats are varied, with respiratory illnesses such as the flu, COVID-19, and respiratory syncytial virus (RSV) viewed as significant risks. Dr. Luis Ostrosky, chief of infectious diseases at UT Health Houston, noted that these illnesses could spread more readily in crowded environments. The U.S. is already enforcing restrictions on travellers from regions affected by the ongoing Ebola outbreak in the Democratic Republic of Congo, mandating a 21-day isolation for athletes from that country prior to their arrival.

While experts like Dr. Amesh Adalja at Johns Hopkins University reassured that Ebola is not a primary concern for the World Cup, they recommend vigilance regarding other illness transmission. Ostrosky asserted that the likelihood of Ebola cases entering the U.S. is low, barring U.S. nationals or residents.

However, the rising incidence of measles in the U.S. poses a more pressing public health threat compared to Ebola. Widespread vaccine hesitancy and the disruption of routine vaccinations during the pandemic have contributed to growing outbreaks of this highly contagious airborne disease. Dr. Steven Goldberg, from HealthTrack, emphasised that measles could exploit existing gaps in vaccination coverage, underscoring its potential risk during large gatherings.

Virologist Andrew Pekosz warned about the implications of crowded events like the World Cup for diseases such as measles. “Crowds are an ideal place for the measles virus to spread,” he said, suggesting that public health officials should be prepared for the likelihood of cases linked to the tournament.

The situation calls for renewed focus on public health preparedness in light of upcoming large-scale events. Cities hosting World Cup matches are being urged to implement monitoring strategies, such as wastewater surveillance, to detect early signs of outbreaks. This proactive approach could help mitigate the risks associated with mass gatherings in the run-up to and during the FIFA World Cup.

In summary, as excitement builds for one of the world’s major sporting events, public health experts are advocating for increased awareness and readiness to manage the potential health crises that could arise from the influx of international visitors. The unique challenges presented by the current leadership gaps and the changing landscape of disease threats highlight the urgent need for robust public health strategies as the World Cup approaches.
