US Rowing is reviewing details of illnesses that 11 athletes suffered while at the Rio 2016 Olympic venue for the World Junior Championships last week, a spokesperson said Monday.

Back in July, the Associated Press reported the water quality at Rio’s water venue showed high levels of viruses and in some cases bacteria from human sewage.

Amid increasing worries concerning the water quality at locations for that Rio de Janeiro Olympics significantly less than annually away the function happened.

Thirteen rowers on the U.S. team came down with a stomach bug at the World Junior Rowing Championships, U.S. officials say. “We were being safe with other things like drinking bottled water, not eating fruits and vegetables with peels”.

Also on the protest was Isabel Swan, a Brazilian Olympic sailing medalist: “To find long-term solutions for a healthier bay, we need to consider everyone who is affected by the pollution”.

“I don’t know if it was the water bottles in the boats, or hygiene precautions that some athletes are really good about and others weren’t”, Ackerman told the AP.

The top of World Rowing, Matt Smith, stated he wishes the regional and IOC planners to request Rio de Janeiro’s state to complete viral screening within the run up towards the Olympics.

IOC medical director Richard Budgett also interviewed team doctors in order to “generally get comfortable with all issues” following the completion of the event, he said. Anyway, Germany seems impervious to water-borne bacteria and viruses.

During its visit, the Commission will tour some of the Games’ venues, meet with the local Government authorities, and hear updates from the Rio 2016 organisers about different areas of Games preparations. It has not been determined whether the polluted water was to blame, and U.S. Rowing spokeswoman Allison Frederick said in a statement Tuesday, “It would be easy, but irresponsible for us to immediately assume that the rowing course is the main or sole point of exposure that caused the illnesses”.

She said that for the athletes, “obviously it’s a concern.it’s a risk” but that “ultimately the Olympic dream is so strong that sometimes we put the pursuit of excellence above our health”.

“If we finish the event at the site of the demonstrations it would not be convenient”, said Rio de Janeiro Mayor Eduardo Paes.

“If I fell in this water right now I could contract anything from a conjunctivitis to an intestinal disorder or even hepatitis A”, he said.

He also said TVB will mainly focus on athletes from Hong Kong, the mainland and Taiwan, and will deploy 100 working staff to cover the Games.
