Eating out, poor hand hygiene and erratic weather may be among causes, say medics
American double world champion pole vaulter Sam Kendricks has been ruled out of the Olympics after testing positive for Covid-19, leading to members of the Australian team being put into isolation on Thursday.
United States Olympic and athletics officials confirmed Kendricks' positive test, tweeting: "The health and safety of our athletes, coaches and staff is our top priority. "In alignment with local rules and protocols he has been transferred to a hotel to be placed in isolation and is being supported by the USATF and USOPC staff."
The immediate knock-on effect was that members of the Australian team have been forced to isolate in their rooms as a precaution.
"Members of the Australian track and field team are now undergoing testing procedures in line with Australian Olympic Team protocols," the Australian Olympic Committee said in a statement.
Games procedures state that athletes who are contact-traced and have not yet competed are isolated from the rest of the squad. They then have to be tested six hours prior to their competition and return a negative result in order to compete. The athletics programme begins on Friday, with the pole vault qualifying event on Saturday.
Australian media reported that all 63 members of the team were in isolation after pole vaulter Kurtis Marschall had been training with Kendricks. .
Kendricks won the world title in 2017 and 2019 and Olympic bronze in Rio 2016 and his battle with world record holder Mondo Duplantis of Sweden was expected to have been one of the highlights of the track and field programme.
"Sam is an incredible and accomplished member of Team USA and his presence will be missed. Out of respect for his privacy, we cannot provide more information at this time," the United States Olympic Committee tweeted.
United States Track and Field (USATF) said that Kendricks and his close contacts were immediately notified and protocols were activated to isolate him.
"We are following the guidance on next steps to ensure the safety of the remainder of our delegation, and to offer support to Sam," USATF tweeted.
