Maryland health officials have identified a positive case of measles in a state resident who recently traveled internationally. The state's Department of Health said in a release Sunday that the resident lives in Howard County, located southeast of Baltimore. The case is not associated with measles outbreaks in Texas and New Mexico, officials said.

Anyone who was at Dulles Airport’s international arrivals area March 5 between 4 p.m. and 9 p.m. EST may have been exposed to measles, a highly contagious airborne disease that can remain infectious in the air and on surfaces for hours after an infected person leaves the area.
