Travelers who were inside the international terminal at Washington Dulles International Airport on June 7 may have been exposed to the measles, WTOP says.
According to the Loudoun County Health Department, an overseas passenger who was infected with the disease was inside both the international terminal and baggage claim area between 6 p.m. and 9 p.m. on that Friday.
No cases of the measles have been reported yet as a result of the exposure, WTOP says, but health officials say that the disease can present up to three weeks after exposure.
According to the Centers for Disease Control, measles presents with symptoms such as fever, coughing, runny nose, watery eyes, muscle aches and a blotchy rash. The disease is contagious enough that 90 percent of people who come into contact with an infected person and are not immunized against measles will contract it, the CDC says.
222 cases of the measles were reported in the United States in 2012, reaching a five-year high according to health officials.
