SINGAPORE - Singapore has confirmed 41 cases of locally transmitted Zika virus, mostly among foreign construction workers, and said it expected more cases to be identified.All but seven of those infected had fully recovered, the Health Ministry and the National Environment Agency said in a statement on Sunday. The seven remain in hospital.On Saturday, authorities confirmed a 47-year-old Malaysian woman living in southeastern Singapore as the city-state's first case of a local transmission of the virus.Zika, carried by some mosquitoes, was detected in Brazil last year and has since spread across the Americas. The virus poses a risk to pregnant women because it can cause severe birth defects. It has been linked in Brazil to more than 1,600 cases of microcephaly, where babies are born with small heads.Singaporean authorities said they tested 124 people, primarily foreign construction workers employed on a site in the same part of Singapore. That site has been ordered to halt work, and workers' dormitories are being inspected. Seventy-eight people tested negative and five cases were pending. Thirty-four patients had fully recovered.
