A construction firm will be prosecuted in court on June 24 after 12 mosquito breeding habitats were found at two of its worksites.
The National Environment Agency (NEA) issued four stop work orders at the D'Leedon and Leedon Residence condominium projects in the Holland area between April 10 and May 15. They are being developed by CapitaLand and GuocoLand respectively.
In a statement on Tuesday, NEA said that 173 dengue cases have been reported in the Farrer-Holland area. It did not name the contractor being prosecuted.
Investigations revealed that dengue transmission in the cluster is likely to have originated from the Leedon Residence construction site as 130 cases involved workers there. The rest involved residents.
The agency said the number of cases has fallen to 13 in the last two weeks. Of these, five were workers and eight were residents. The last instance of breeding was found on May 20.
It has also completed four rounds of inspections at 450 residential premises in the cluster, as well as at the two construction sites.
A total of 56 breeding habitats were destroyed - 12 of which were at the sites.
The contractor has since stepped up its housekeeping regime and mosquito control measures, the NEA said. It has also taken steps to protect its workers by issuing repellents and carrying out daily fever screening.
No breeding has since been detected in subsequent checks of the two sites, after the lifting of the stop work orders.
The NEA added that it is also doing further checks at residential premises in the area where 30 breeding habitats were found.
