Ciccozzi on the pollution of the Seine: a dangerous cocktail for athletes
Concerns about the swimming competitions. “In Italy, we would never have taken such a risk”
The epidemiologist Massimo Ciccozzi of the University Campus Bio-Medico in Rome has expressed strong concerns about the choice to play swimming competitions of the Paris 2024 Olympics in open water in the Seine. “In Italy, with our high health standards, we would never have taken such a risk,” said Ciccozzi.
A cocktail of pathogens
The waters of the Seine, like many large urban rivers, are contaminated by a wide range of pathogenic micro-organisms. Among the most immediate risks for athletes, Ciccozzi cites:
- Escherichia coli: This bacterium, common in wastewater, can cause severe gastroenteritis, with symptoms such as diarrhea, vomiting, fever and abdominal pain
- Salmonella: Another enteric bacterium that can cause severe intestinal infections, sometimes with systemic complications
- Leptospirosis: A zoonotic bacterial infection that is contracted through contact with water or soil contaminated by urine of infected animals
- Giardia and amoebas: Intestinal parasites that can cause prolonged diarrhea, malabsorption and, in severe cases, damage to internal organs
- Hepatitis A: A virus that is transmitted through contact with contaminated feces and can cause acute hepatitis.
Consequences for athletes
Infection with one of these pathogens can have significant consequences for an athlete. In addition to acute symptoms such as diarrhea and vomiting, these infections can lead to dehydration, malnutrition and a deterioration of athletic performance. In some cases, infections can be prolonged and difficult to treat, requiring antibiotic or pesticide therapy.
Risk prevention and management
To reduce the risks associated with bathing in contaminated waters, Ciccozzi suggests that stringent preventive measures be taken, such as:
- Constant monitoring of water quality: An effective monitoring system to identify any possible contamination at an early stage
- Preventive treatment: The use of skin disinfectants and specific water disinfection products may offer some protection
- Vaccinations: Hepatitis vaccination
Responsibility of the Olympic organisers
The decision to have Olympic athletes compete in contaminated waters such as the Seine raises serious concerns for public health and the responsibility of the Olympic organizers. It is essential that the organisers take all necessary measures to ensure the safety of athletes and minimise risks to their health.
