In reply to Chris the Tall:
> Of course the IAAF couldn't put him in quarantine- they don't have power to do that ! All they can do is deny him entry to the buildings under their control- suspend his accreditation- but they can't stop him walking the streets.
I know they don't, and nor does anyone else without a court order, despite the tone of the IAAF statement. Given that they did what they did to prevent spread among the athletes and staff, I think it could have been done while allowing him to compete. What they actually did achieved practically nothing except stopping him from competing.
I appreciate it's a difficult balance.
I also trust what the IAAF are saying he reported his symptoms as, and think they were sensible in presuming that norovirus is what he had.
