Risk of Zika Spreading Globally During Olympics 'Very Low'

The World Health Organization (WHO) said Tuesday that the risk of the Zika virus spreading internationally during the Rio Olympics was "very low."

In just under two months, hundreds of thousands of athletes and spectators from all over the world will descend on Brazil for the 2016 Olympic Games. But many are concerned the mosquito-borne disease, which has been linked to the birth defect microcephaly in new-born babies, could spread during the mass gathering.
