SINGAPORE - Two locally transmitted cases of the Zika virus have been confirmed at Simon Place, near Kovan in Hougang. Both are residents from the same household.
The cluster was notified on Tuesday (March 28) and vector control operations are being carried out. MOH declined to reveal personal details of the two, but The Straits Times understands neither is pregnant.
Apart from the two new cases, there have been six other isolated Zika cases detected in Singapore this year.
A cluster is formed when at least two cases have onset within 14 days and are located within 150m of each other.
Residents should remain vigilant in detecting mosquito breeding spots, as there could still be asymptomatic or mild, undiagnosed cases which can cause further transmission of the virus.
The National Environment Agency (NEA) has commenced vector control operations and outreach activities at the cluster.
As of Wednesday (March 29), NEA has inspected about 120 out of some 400 premises in Simon Place for mosquito breeding, alongside ground checks in the vicinity.
Seven breeding habitats in homes and three in other premises have been detected and destroyed.
Indoor spraying of insecticides, together with thermal fogging and misting at outdoor areas, have been carried out.
NEA officers and grassroots volunteers are distributing information leaflets and insect repellents to households, to raise awareness of Zika.
They also stress the need to prevent mosquito breeding, and tell residents to apply repellent as a precaution.
Residents are requested to allow NEA officers to carry out inspections and indoor spraying of their homes.
The five-step Mozzie Wipeout should also be practised.
Aljunied GRC MP Sylvia Lim said: "I thank NEA for its concerted work and urge residents to cooperate fully and to exercise personal vigilance."
Ms Lim added that she would be visiting some residents in the affected cluster on Thursday.
Most people infected with the Zika virus do not develop symptoms, so it may take some time before a reintroduced virus is detected.
Members of the public are advised to seek medical attention if they are unwell, especially with symptoms such as fever and rash.
They should also inform their doctors of the location of their residence and workplace.
