In a follow-up to the rapidly spreading Zika virus outbreak in Singapore, the Ministry of Health has reported an additional 26 new confirmed cases of locally transmitted Zika virus infection on Saturday. This brings the outbreak total to 215 cases.

Of the new cases, 24 are linked to the Aljunied Crescent/ Sims Drive/ Kallang Way/ Paya Lebar Way cluster. Two cases have no known links to any existing cluster.

The National Public Health Laboratory has worked with A*STAR’s Bioinformatics Institute to complete the sequencing analysis of the Zika virus found in two patients from the Aljunied Crescent/ Sims Drive cluster. The analysis found that the virus belongs to the Asian lineage and likely evolved from the strain that was already circulating in Southeast Asia. The virus from these two patients was not imported from South America.
