Two cases of locally-transmitted Zika virus infection in Singapore have been confirmed at Kensington Park Drive today.

Both cases involved residents in the vicinity, said the National Environment Agency (NEA) in its website.

"This new cluster was notified today, and the NEA has commenced vector control operations at the cluster area," said the agency.

The NEA said it had been conducting preventive inspections in the vicinity before notification of the cluster at Kensington Park Drive to detect and destroy any potential mosquito breeding habitats.

NEA noted that most people infected with the Zika virus did not develop symptoms which heightened the risk of a Zika resurgence as it might take some time before a reintroduced Zika virus was detected.

The first Zika cluster at Simon Place near Kovan in Hougang was the first reported this year in Singapore on March 29.

It was then reported at Flower Road and Hendry Close area on April 6; Poh Huat Terrace and Terrasse Lane area (April 11); Glasgow Road (April 20); Highland Road and Jansen Close (April 25) and Parry Avenue at the Serangoon Garden area (June 9).
