The Communicable Diseases Agency (CDA) and NEA have confirmed two local Zika cases at Woodlands Street 11 and Street 32. Following each case notification, NEA commenced wastewater and mosquito surveillance surrounding the residential areas. This enhanced surveillance has revealed persistent Zika virus signals in the area, which suggests that this is an area with likely Zika transmission. Similar to the dengue virus, the Zika virus infection is transmitted by the Aedes mosquito. We advise residents in the area, especially pregnant women, to protect themselves from mosquito bites and to monitor their health closely. Persons showing symptoms suggestive of Zika infections should see a doctor early, to be diagnosed and managed accordingly. Protect yourself and your loved ones by carrying out the ‘S-A-W’ and ‘B-L-O-C-K’ actions. Visit go.gov.sg/zikaclusters for information on Zika cases, and CDA’s webpage (go.gov.sg/zika) for Zika symptoms, prevention and treatment options.
