RIO DE JANEIRO - The Arkansas Department of Health says a person who recently traveled out of the United States has tested positive for the Zika virus.

The department says that the person has a mild case of Zika, which is spread by mosquitoes and is suspected of causing a spate of birth defects in Brazil. Spokeswoman Meg Mirivel would not say whether Tuesday if the infected person is a man or woman or give the person's age.

Mirivel says the individual traveled to the Central America-Caribbean region, though she would not specify which country. Some U.S. travelers have been infected abroad with Zika but there are no cases of local infection in the U.S. so far.

Brazilian officials have linked the virus with a rare birth defect, and the U.S. Centers for Disease Control and Prevention have urged pregnant women to consider postponing flights to areas where the virus is prevalent.
