In the first stage, which lasts two to four days, the individual may have a runny nose, cough and a slight fever. Eyes may become reddened and sensitive to light while the fever gradually rises each day, often peaking as high as 103° to 105° F. Small bluish white spots surrounded by a reddish area may also appear on the inside of the mouth.

The second stage begins on the third to seventh day and consists of a red blotchy rash lasting five to six days. The rash usually begins on the face and then spreads downward and outward, reaching the hands and feet. The rash fades in the same order that it appeared, from head to extremities. A person can spread measles from 4 days before the onset of rash through 4 days after the rash begins. Although measles is usually considered a childhood disease, it can be contracted at any age.
