Four people in Miami likely contracted Zika locally through mosquito bites, Florida's governor said on Friday, the first evidence that the virus tied to a rare but serious birth defect is circulating in the continental United States.
Governor Rick Scott said the state believed active transmission of the virus was occurring within an area of Miami about the size of a square mile (2.6 square kms). Testing showed that one woman and three men had been infected, Scott said.
While health officials have yet to identify mosquitoes carrying the virus, the state has ruled out other means of transmission, including travel to another country with a Zika outbreak, and sexual contact.
