The measles rash is caused by a virus. A week or two after exposure, symptoms like high fever, nasal congestion, and a runny nose begin. The rash usually appears a few days after these initial symptoms. Small raised bumps start on the face and spread downward, sometimes reaching the feet. The bumps may join and appear more as large red patches than individual spots.
