Officials with Singapore’s National Environment Agency (NEA) confirmed Friday two cases of locally transmitted Zika virus infection at Parry Avenue. Both cases are residents in the vicinity.

The NEA began vector control operations at the cluster area.

The community is urged to maintain vigilance and continue to eliminate mosquito breeding habitats, as there could still be asymptomatic or mild, undiagnosed cases which might result in further transmission of the virus if there are mosquitoes in the vicinity.

Residents are requested to allow NEA officers to carry out inspections and indoor spraying of their homes.

Most people infected with the Zika virus do not develop symptoms, which heightens the risk of a Zika resurgence as it may take some time before a reintroduced Zika 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.

Zika is generally a mild disease. It may cause a viral fever similar to dengue or chikungunya, with fever, skin rashes, body aches, and headache. But many people infected with the Zika virus infection do not even develop symptoms.

Pregnant women with symptoms of possible Zika virus infection (fever and rash and other symptoms such as red eyes or joint pain) should seek medical attention immediately.
