The Ministry of Health (MOH) said that 24 new cases have been identified and a new potential cluster has been discovered at Bedok North Avenue 3.
A pregnant woman living in the Aljunied Crescent/ Sims Drive area was tested positive for Zika virus infection.
MOH said: “Her doctor is following up closely with her to monitor her health and the development of her baby. She will be referred to a maternal-foetal medicine (MFM) specialist for counselling and advice.”
Meanwhile, the National Environment Agency (NEA) is accelerating its vector control efforts to wider areas.
Minister for Health Gan Kim Yong said: “Over time, we expect Zika cases to emerge from more areas.
“We must work and plan on the basis that there is Zika transmission in other parts of Singapore and extend our vector control efforts beyond the current affected areas.”
The Zika virus, is spread to people through mosquito bites, was declared an international public health emergency by the World Health Organization.
In June this year, the US House of Representatives approved a bill to provide $1.1bn funding to combat the Zika virus.
