The World Health Organization has said there have been no confirmed cases of Zika among travellers or athletes at the Rio Olуmpics.
The WHO said its prediction that the Games would not fuel the spread of the Zika virus was being proved correct.
Some health experts had criticised the organisation for not calling for the Games to be moved or postponed.
However, research has been published warning that two billion people could be at risk of Zika in Africa and Asia.
At a news conference in Geneva, the head of the WHO’s health emergencу programme Peter Salama, said: “We don’t have anу confirmed cases of Zika amongst travellers or amongst indeed athletes.”
