A woman is being treated in a hospital after contracting measles. She is part of a family that has been affected by the illness. Health officials have linked the family's exposure to a person who traveled from another state with a confirmed measles infection.

The case is the fourth in Montgomery County. The patients involved, including the latest one, have something in common: they did not receive a vaccine against the illness. Further information about the cases is available from the Montgomery County Public Health department.
