The victims included Botswana's Isaac Makwala, who was ordered by the global athletics body, IAAF, to withdraw from Tuesday evening's 400 meters final, where he had expected to be the lead challenger to world record holder Wayde van Niekerk.
After initially struggling with the cold, the 25-year-old ran a solid final bend to blast to victory in 43.98 seconds with a lot to spare, and went straight into recovery ahead of yesterday's 200m semi-finals, with the final today.
He signalled his confidence in his fitness to run by celebrating his progression to the semis with a series of press-ups.
Makwala ran an individual time trial to qualify for the 200m semi-finals after he missed the 200m heats and the 400m final as he was barred from competing for 48 hours while organisers tried to halt a norovirus outbreak.
The biggest news from London's World Championships this week has been Isaac Makwala's exclusion from racing in the men's 400m.
"Year to year I just went from strength to strength, from South African records to world record and now I think the sky is literally the limit".
"I've got a good team who will help me recover well for the 200m and I'm looking forward to that".
If anyone in the London Stadium on Wednesday night had seen a more surreal, or heartwarming, piece of sporting theatre this year, they are very lucky.
"I am heartbroken. I feel like it is sabotage".
"It's only because I'm not a Great British athlete".
"I wish the IAAF had given me the decision to run the 400m first".
Unlike the 200 the day before, from which Makwala had voluntarily withdrawn, it was IAAF's decision to withdraw Makwala, who traveled to the arena ready to compete despite being under quarantine.
Isaac Makwala is getting a belated chance to compete in the 200 meters with a solo run and one opponent - England's world famous rain.
In a statement the IAAF confirmed there had been an outbreak of gastroenteritis, and that the athletes affected were being looked after by medical staff.
But Botswana officials said they had received no explanation as to why Makwala was not allowed entry, and had not been told to keep the runner in quarantine.
"I told myself: 'I am Olympic champion, ' and that others must break me", Kipruto said.
From heartbreak to hope for an athlete who experienced 24 hours like no other at the IAAF World Championships in London. South Africa's Caster Semenya, the 2009 world champion and twice Olympic gold medalist in the 800 meters, outsprinted Britain's Laura Muir and Sifan Hassan of the Netherlands, throwing herself at the line to take bronze.
More than 30 athletes and support staff had been affected by sickness at the Tower Hotel in London.
Eight-time Olympic champion Bolt, the fastest man in history, has been glowing in his praise, backing Van Niekerk to "take over" athletics in a recent interview with CNN.
