Singapore on Sunday confirmed 41 locally transmitted cases of the Zika virus, which can cause deformities in unborn babies, and said more infections are likely.
Spanish health authorities say they have detected the country's first known case of the microcephaly birth defect in the foetus of a pregnant woman infected with the Zika virus.
