Botswana's star run machine Isaac Makwala was denied entry into the stadium after he was reportedly hit by the norovirus bug
Botswana's star run machine Isaac Makwala was denied entry to the London stadium which is hosting the World Athletics Championships after the runner was reportedly hit by the norovirus bug in his hotel.
"Isaac Makwala was withdrawn from the men's 400m (Final) due to a medical condition on the instruction of the IAAF medical delegate," world athletics' ruling body said in a statement.
However, Makwala tried to get into the warm-up track at the London stadium ahead of the final but was denied entry by security personnel leading to huge furore during the event.
"There have been no medical tests at all, it's just generalised assumptions because of the outbreak of sickness and he has just one of those symptoms," he told the BBC.
The IAAF issued a second statement later on Tuesday saying Makwala had been diagnosed with an "infectious disease" following an examination by a doctor in the warm-up medical centre on Monday.
"The team doctor, team leader and team physio had been informed following the medical examination that the athlete should be quarantined for 48 hours and would, therefore, be missing the 400m final on Tuesday," it said.
"The IAAF is very sorry that the hard work and talent of Isaac Makwala won’t be on display tonight but we have to think of the welfare of all athletes."
The Botswana's athletics federation chief, Falcon Sedimo hit back, saying, "There has been no official communication, no formal communication from the IAAF at all." However, the IAAF in its statement denied the allegation, reiterating the player had been informed prior to the event.
Meanwhile, at least 30 athletes at the world athletics championships have been infected in a suspected outbreak of norovirus, reports said.
