The New Hampshire Department of Health and Human Services is investigating a possible measles exposure case after a foreign traveler who visited Hanover this month tested positive.

The DHHS said the international traveler tested positive for measles upon his return.

According to DHHS, the traveler made several stops in the Hanover area, including on the campus of Dartmouth College, at the Hanover Inn and on a bus from Hanover to Boston's Logan Airport.

State authorities said there were no confirmed cases of measles in New Hampshire.
