In Singapore, eight pregnant women are among the 329 who have been infected by the Zika virus. 

Local authorities said 11 new cases of locally-transmitted Zika were confirmed on Sunday. The city-state reported its first locally infected Zika patient on August 27th. Since then, the number of reported infections has risen to more than 300.

Zika infections in pregnant women have been shown to cause microcephaly, a severe birth defect in which the head and brain are undersized. In adults, it can cause a rare neurological syndrome called Guillain-Barre.
