SINGAPORE - There are 15 more cases of locally transmitted Zika virus infection in Singapore, the Ministry of Health (MOH) has said.
Of the 15, two work at the construction site at 60, Sims Drive, and they have recovered.
Thirteen live or work in the broader Sims Drive and Aljunied Crescent area, where 41 cases were earlier found.
With the new cases, there is now a total of 56 confirmed cases here.
MOH said it has completed testing of all workers at the construction site who had previously shown symptoms of fever and rash.
The Ministry is also screening workers staying at the dormitories located near the affected areas.
"MOH will continue to work with GPs in the area to offer testing for patients who had fever and rash previously," MOH said. "The look-back exercise will likely uncover more previously undiagnosed cases of Zika."
As of Sunday (Aug 28), the National Environment Agency (NEA) has inspected about 3,600 premises out of an estimated 6,000 premises in the Aljunied Crescent and Sims Drive cluster to check for mosquito breeding.
It has also conducted ground checks in the vicinity.
The agency found 36 breeding habitats, which have been detected and destroyed.
NEA has also inspected the on-site workers quarters at the construction site at Sims Drive.
NEA officers and grassroots volunteers have completed the first round of outreach efforts in the area, to distribute Zika information leaflets.
"We will be continuing with outreach to raise general awareness of Zika, reiterate the need for source reduction to prevent mosquito breeding, and advise residents to apply repellent as precaution," NEA said.
NEA has also started vector control operations in areas where Zika patients from the Aljunied Crescent and Sims Drive cluster work or live.
NEA has begun inspecting dormitories and homes at Kranji Road, Senoko South Road, Lorong 101 Changi, Toh Guan Road East and Joo Chiat Place.
Two breeding habitats were found at Kranji and at Sembawang Drive.
Thermal fogging, misting and indoor spraying of insecticides have been carried out at the inspected premises.
"There is currently no evidence of local transmission in these areas of concern," authorities said.
