As soccer fans across North America celebrate the World Cup, health officials remain vigilant against potential disease outbreaks. While a heatwave is a prominent concern, the spread of infectious diseases in large gatherings takes center stage.
Monitoring Potential Outbreaks
Measles, one of the most contagious diseases, is a top concern prompting a warning from the Pan American Health Organization (PAHO). With events spanning nearly six weeks in 16 cities, officials are on the alert for infections like norovirus and dengue fever.
“This is truly a marathon,” said Palak Raval-Nelson, Philadelphia’s health commissioner.
Challenges Facing Health Agencies
In the U.S., budget constraints challenge health agencies. The Centers for Disease Control and Prevention (CDC), impacted by previous staffing cuts, is already managing an Ebola outbreak in Africa and a hantavirus outbreak on a cruise ship. Despite advising state and local departments, a World Cup disease surveillance dashboard was still in development nearing the event, according to the Department of Health and Human Services.
Global health specialist Rebecca Katz of Georgetown University leads a new hub to aid health efforts. The Health Security Operations Center, a collaboration between Georgetown and MedStar Health, analyzes data nationally to alert authorities to early trouble signs.
“It’s important that we don’t become alarmist,” said MedStar emergency medicine specialist Dr. Shane Kappler. “We’re trying to be the insurance policy.”
Focus on Measles and Other Threats
Already this year, over 2,000 measles cases have been reported in the U.S., nearly matching last year’s total. Measles spreads before symptoms appear, leading to concern among international partners about importing the virus. PAHO reports measles cases are rising in Canada and Mexico.
Dr. Craig Spencer of Brown University, an Ebola survivor, highlights measles and other infectious threats as greater concerns than Ebola for the World Cup, noting the low risk of Ebola spreading in the U.S. due to travel screenings and its transmission through bodily fluids.
“One fortunate thing about this virus is you’re most contagious when you’re really quite ill,” said Jennifer Nuzzo, director of Brown’s Pandemic Center.
Surveillance and Detection Efforts
Detecting disease during sporting events is critical. Canadian scientists linked a measles outbreak to the 2010 Olympics, and recent Olympics faced norovirus challenges. Wastewater testing, which detects genetic material from viruses, is a vital tool.
This week, surveillance reports noted the detection of rotavirus, hepatitis A, and norovirus in parts of the U.S. In Dallas, enhanced wastewater screening targets broad detection, while mosquito testing aims to catch viruses like dengue and chikungunya.
Phil Raval-Nelson emphasizes the importance of preparation with mock emergency drills and communication with health counterparts to ensure readiness.
