Measles outbreak tracked in Maryland
Health officials in Maryland say four people have been diagnosed with measles in the state's first outbreak since 2001.
Three of the four cases are linked to a Montgomery County man who contracted measles outside the United States in February, The Washington Post reported Tuesday.Health officials said most recent measles outbreaks occur in foreign-born residents who have never been immunized. Immigrants seeking citizenship and children starting school must show proof of measles vaccination, the newspaper said.
