Symptoms of measles generally start with:
• High fever
• Cough
• Runny nose
• Red, watery eyes
2–4 days after initial symptoms, a rash starts at the hairline and moves down the body to the neck, arms, torso, and legs.
Incubation Period is 7–21 days. Contagious Period is 4 days before the rash onset to 4 days after the rash onset.
Recommended Actions: Call the local health department immediately to report all rashes accompanied by fever. Isolate, exclude, and refer to a health care provider for diagnosis.
Cases: Exclude from the time of onset of illness through the 4th day after rash appears, and until the individual is fever-free without the use of fever-reducing medications
