Health officials confirmed a second person has the measles in Maryland.
The person is a "household contact" of the first patient the Maryland Health Department announced had the measles earlier this month.
They both got the measles in an another area of the country with an ongoing outbreak. The health department did not specify which area.
Officials said there's no evidence of an outbreak in Maryland and no new exposure locations have been identified.
On April 5, the health department said that anyone who visited 4000 Old Court Road in Pikesville in Baltimore County between 9 a.m. and 1 p.m. on April 2 may have been exposed to measles.
The health department said people who were at the Pikeville address, especially those who aren't vaccinated, should monitor themselves for any early symptoms of measles, including fever. People who develop symptoms of measles should contact their health care provider, but should not go to child care, school, work or out in public, as they might have early symptoms of measles and might be contagious.
