The head of the International Olympic Committee says steps are being taken to protect the Games in Rio de Janeiro.Thomas Bach said the IOC would issue advice this week on how to keep athletes and visitors safe in Brazil, the worst affected country. WHO director general Dr Margaret Chan said Zika had gone “from a mild threat to one of alarming proportions”.
