The first locally-contracted case of the Zika virus has been confirmed in the Cayman Islands, the Caribbean nation's health department said.
The patient, a man, reported the first symptoms in late July and a sample was sent to the Caribbean Public Health Agency for testing. He had not traveled to any countries in which Zika is present, the department said in a statement late Monday.
It came hours after Florida said health officials were investigating a new case of Zika in Palm Beach County that appears to be a local transmission.
The person recently traveled to Miami-Dade County, Gov. Rick Scott said in a statement Monday.
Scott said the state still believes active transmissions of the virus, which can cause a rare but devastating birth defect, are taking place only in a 1-square mile area in Miami-Dade County that includes the Wynwood district.
Health authorities say infection with the Zika virus in pregnant women can cause the birth defect microcephaly and other severe brain abnormalities in babies.
