Tests for pregnant women urged as Zika cases soar

Singapore urged all pregnant women showing symptoms of fever or rashes to have themselves tested for the Zika virus on Wednesday after the number of cases in the city-state soared to 82.

The United States and Britain joined Australia and Taiwan in advising pregnant women to avoid nonessential travel to the city-state.

Environment agency workers stepped up efforts to eradicate mosquitoes that spread the disease, expanding a fumigation campaign centered on the "ground zero" of the outbreak, the eastern suburb of Aljunied.
