Zika forces S'pore travel warnings

Confirmed cases of Zika virus in Singapore rose to 82 on Tuesday, as the United States joined a growing list of countries, Australia, Taiwan and South Korea, warning pregnant women or those trying to get pregnant to avoid travel to the city-state. The warnings followed news that Zika transmission appears to be occurring outside of the original cluster, with at least five of 26 new cases confirmed late on Tuesday.
