A student at the College of William & Mary in Williamsburg, Va., has contracted the Zika virus, but appears to pose no health risk, according to school officials.

The student was traveling in Central America during the college’s winter break, officials said in an online statement.

The Zika virus, carried by mosquitos, is now in two dozen countries and territories across the Americas. Brazil has been reported as the epicenter, and some health experts believe it could cause an abnormally small head and brain in babies born to mothers who contracted Zika while pregnant.

Symptoms include fever, rash, joint pain and other ailments similar to the flu.

Scientists have begun to connect the Zika virus to steep rises in a serious birth defect and a rare autoimmune disorder.

The statement added that college’s health team and the Center for Disease Control (CDC) believed there is “believed to be no health risk to anyone on campus.” The college gave no further details on the student.

“It is our understanding that, thankfully, the student is expected to recover fully and is not currently experiencing symptoms,” the college said.

The World Health Organization has said it will hold an emergency meeting to try to find ways to stop the spread of the virus. It is expected that the virus, which is spreading rapidly, could infect up to 4 million people in 12 months.
