The Singapore Health Ministry (MOH) has confirmed 15 more cases of locally transmitted Zika virus infection in the republic as of noon today, Channel NewsAsia reported.

Quoting the ministry and the National Environment Agency (NEA), the report said two of the cases were at a construction site at 60 Sims Drive and had recovered.

It added that 13 cases lived or worked in the broader Sims Drive/Aljunied Crescent area.

The two cases at the Sims Drive construction site were detected as a result of MOH's look-back and testing of potentially infected persons.

As of today, the report said MOH had completed testing of all workers at the construction site, who had symptoms of fever and rash previously.

"We are also screening workers staying at the dormitories located in the areas of concern," the authorities were quoted as saying.

The report said MOH would continue to work with general practitioners (GPs) in the area to offer testing for patients who had fever and rash previously.

The look-back exercise would likely uncover more previously undiagnosed cases of Zika, it added.

As of today, the report said the NEA had inspected about 3,600 premises out of an estimated 6,000 premises in the Aljunied Crescent/Sims Drive cluster to check for mosquito breeding, and also conducted ground checks in the vicinity.

It said 36 breeding habitats - comprising 22 in homes and 14 in common areas/other premises - had been detected and destroyed.

The report said the NEA had also inspected the on-site workers quarters at the construction site at Sims Drive.

NEA has also commenced vector control operations in areas of concern where cases from the Aljunied Crescent/Sims Drive cluster work or live.

There is currently no evidence of local transmission in these areas of concern, MOH and NEA reportedly said.
