On Thursday, a student from White Mountain School in Bethlehem went to the emergency room at Littleton Regional Healthcare with mild flu-like symptoms. The student had traveled to Hunan and returned to the U.S. on January 6.

Samples from the two individuals have been sent to the U.S. Centers for Disease Control and Prevention for testing.
