No Zika threat to Rio, says CDC chief

There is no reason to postpone the Olympics in Rio over the Zika virus, says US government scientist Thomas Frieden of the Centers for Disease Control.

More than 100 scientists have written a letter to the World Health Organization calling on the Games to be moved or postponed.

But Mr Frieden told the BBC the risk is to pregnant women and the Games should proceed.
