The mosquito-borne disease outbreak affected three dozen workers on a construction site and they all test positive with Zika.

US health officials have concluded that Zika infections in pregnant women can cause microcephaly defect.
It is a birth defect marked by small head size that can lead to severe developmental problems in babies.
