Lane County Public Health says a healthy adult male who’d been traveling in the Caribbean contracted it.
The virus is transmitted through mosquito bites.
It first appeared in the Caribbean in 2013 and has since spread rapidly throughout the southern U.S.
The most common symptoms are fever and joint pain, three to seven days after it’s transmitted.
It is rarely fatal, and symptoms can be relieved through bed rest, hydration, and over-the-counter medication.
