Kenya threatened on Tuesday to pull its elite runners and other athletes out of the Rio Olympics unless it got assurances they would not be exposed to the Zika virus outbreak in Brazil. Sports authorities across the world are scrambling to find out more about the mosquito-borne virus as they make plans for the games in August. "Obviously, we are not going to risk taking Kenyans there if this Zika Virus reaches epidemic levels. They have to assure us that the country is safe enough to take athletes there," the head of Kenya's Olympics committee, Kipchoge Keino, told Reuters.
