SINGAPORE, April 6 (Xinhua) -- Singapore discovered another new Zika cluster at Flower Road/Hendry Close, nearing to the North-East Region, said National Environment Agency (NEA) in a press release on Thursday.
NEA has commenced vector control operations in the affected regions. The agency urged the residents and stakeholders to maintain vigilance and continue to eliminate mosquito breeding habitats.
There could still be undiagnosed cases which may result in further transmission of the virus, it added.
Together with grassroots volunteers, NEA also distributes Zika information leaflets and insect repellents to households to raise general awareness of Zika.
As most people infected with Zika do not develop symptoms, it could increase the risk of a resurgence of the virus as "it may take some time before a reintroduced Zika virus is detected", NEA added.
Two cases of locally transmitted Zika virus infection in Singapore were confirmed last month.
