Olympic Games 2016: Rio de Janeiro's polluted waters might put athletes' health at risk

The video discusses water testing conducted by a top Brazilian virologist at Olympic sites in Rio de Janeiro, focusing on human adenoviruses, enteroviruses, and rotaviruses. The tests revealed high levels of infectious adenoviruses, posing health risks such as diarrhea and respiratory issues. Despite Rio's promise to reduce sewage in Guanabara Bay by 80% for the 2016 Olympics, only 49% was treated by 2015. Over 10,000 athletes from 200 countries participated in the Olympics, with 1,400 potentially exposed to contaminated waters.
