Belgian Olympian who got sick after swim in Seine River says virus caused her illness, not E. coli

Paris — A Belgian triathlete who fell ill, causing her team to withdraw from mixed relay event at the Paris Olympics, said blood tests showed it was a virus that made her sick.

Belgium's Olympic committee announced Sunday that it would withdraw its team from Monday's triathlon mixed relay because Claire Michel was unable to compete. Michel had competed a few days earlier in the women's triathlon, which included a swim in the Seine River.

Bacteria levels in the long-polluted river have been in flux during the Games, causing test swims ahead of the triathlon events to be canceled and the men's triathlon to be delayed by a day. Organizers had said that water quality tests done the day of the individual triathlon races showed "very good" levels of fecal bacteria E. coli and enterococci.
