In a joint statement by Ministry of Health (MOH) and National Environment Agency (NEA), they announced that as of 12 pm, 1 September, another 36 confirmed cases of Zika virus infection, which brings the total number to 151 cases in just within 4 days.
Among those, 3 cases were not related to any existing clusters. They live in Tagore Avenue, Yishun Street 81 and Harvey Crescent.
One of the cases which were confirmed on Thursday is a pregnant woman and her doctor is following up closely on her to provide support and counselling.
5 of the cases were from a look-back testing of the previous case which was conducted by MOH. The look-back exercise was completed. MOH took a total of 236 samples. 52 of these were confirmed positive, while the rest of 184 were negative.
NEA states that vector control remains the key to control the disease, systematic and holistic approach through surveillance, prevention and control, outbreak management and outreach to arrest mosquito borne transmission in Singapore. Its objective is to keep mosquito borne disease incidence low through reducing the mosquito population and breaking the disease transmission chain.
The statement states that the approach of tackling Zika disease is similar to the one for dengue cases. It conducts checks for mosquito breeding habitats based on cases, as well as takes a preventive and risk-based approach through pre-emptive checks in areas assessed to be at higher risk, even in the absence of cases.
Premises owners are advised to ensure proper housekeeping within their premises at all times to remove potential mosquito breeding habitats. They should be doing the 5-step Mozzie Wipeout, which includes simple steps such as inverting pails and plant pot plates, and changing the water in vases regularly. They are also advised to apply larvicide in stagnant water to kill larvae, fog open areas when the mosquito population is high and spray insecticides in indoor spaces to kill adult mosquitoes.
NEA had conducted indoor spraying, misting and oiling. Daily misting of common areas is also ongoing in the existing Aljunied Crescent/Sims Drive cluster. It had completed two rounds of thermal fogging, with one more round to be conducted this week. So far NEA had detected and destroyed 49 breeding habitats, comprising 26 in homes and 23 in common areas/other premises.
Vector control operations and outreach efforts in Bedok North Avenue 3, Punggol Way and Joo Seng today also had been conducted.
NEA stated that its officers and grassroots volunteers have completed outreach efforts to distribute Zika information leaflets in the Aljunied Crescent/Sims Drive cluster, and have commenced outreach in the expanded cluster areas in Paya Lebar Way/Kallang Way.
" Residents are urged to cooperate fully with NEA and allow its officers to inspect their premises for mosquito breeding and to spray insecticide to kill any mosquitoes. NEA may need to gain entry into inaccessible premises by force after serving of requisite Notices, to ensure any breeding habitats are destroyed quickly," it wrote.
