Nine new cases of locally transmitted Zika were confirmed on Thursday (Sep 8), bringing the total number of confirmed cases to 292, the Ministry of Health (MOH) and National Environment Agency (NEA) said in a joint statement.
The authorities added that there is a potential new cluster involving two previously reported cases and a new case, all of whom work in the Ubi Crescent area. One of the previously unlinked cases in the cluster was reported on Sep 7, and his work address was verified on Thursday.
Of the other new cases, authorities said four cases are linked to the Aljunied Crescent/ Sims Drive/ Kallang Way/ Paya Lebar Way cluster; one is linked to the Bishan Street 12 cluster; and another case is linked to the Elite Terrace cluster.
The other two cases have no known links to any existing cluster.
NEA said it will be carrying out vector control operations and outreach efforts at the potential new cluster at Ubi Crescent.
The agency added that it is continuing with vector control operations and outreach efforts in the cluster areas at Aljunied Crescent / Sims Drive / Paya Lebar Way / Kallang Way / Circuit Road / Geylang East Central / Geylang East Avenue 1; Bedok North Avenue 2 / Bedok North Avenue 3 / Bedok North Street 3; Joo Seng Road; Bishan Street 12 and Elite Terrace in Siglap.
NEA said that as of Sep 7, a total of 166 breeding habitats have been found and destroyed in the cluster areas, of which 108 are from homes, and 58 from outdoor areas.
It added that updated information on Zika and details of current clusters are available on its website.
Earlier on Thursday, authorities said that analysis of two locally transmitted Zika cases showed that they were not recently imported from South America. Instead, the virus likely belongs to a strain circulating in Southeast Asia since the 1960s.
