Health officials in Montgomery County fear that a local resident who contracted measles may have exposed others to the contagious disease.
Officials say the unidentified resident had traveled to Malawi in southern Africa. An outbreak there killed dozens of people and sickened thousands more this year.
County officials say the resident had visited several area supermarkets and health facilities between July 27 and Aug. 3, as well as Philadelphia International Airport and Longport, N.J.
