15 new cases confirmed for a total of 56 as the city-state steps up prevention efforts

Singapore confirmed 15 new cases of locally-transmitted Zika infections on Monday, taking the tally to 56 as authorities step up efforts to contain the outbreak.

All the cases were in or near the Aljunied area in the southeast of the city-state, and most were foreign workers from a nearby construction site owned by GuocoLand, where testing for the virus is now complete, the Health Ministry said.
