Singapore on Saturday reported 215 cases of Zika infections as scientists in the city-state said the virus strain comes from within Asia and was not imported from Brazil.

The Ministry of Health and National Environment Agency said in a joint statement on Saturday evening that of the 26 new cases reported on Saturday, 24 were linked to a cluster in the Aljunied district where the country's first locally-transmitted cases were reported.

The statement did not say where the other two cases were from.
