The first locally contracted case of the Zika virus has been confirmed in the Cayman Islands.

The male patient reported symptoms in late July and a sample was sent to the Caribbean Public Health Agency for testing. He had not travelled to any countries in which Zika is present, the Cayman Islands’ health department said in a statement on Monday.

Health authorities say infection with the Zika virus during pregnancy can cause microcephaly, a birth defect marked by small head size that can lead to serious developmental problems, and other severe brain abnormalities in babies.
