1. Incubation period: The incubation period of measles is generally 10-14 days, but can be as short as about 1 week. There may be a slight rise in body temperature during the incubation period.

2. Prodromal period: The prodromal period of measles is also called the pre-eruptive period, which usually lasts 3-4 days. The main manifestations of this stage are similar to those of upper respiratory tract infection: fever, cough, runny nose, tearing, pharyngeal congestion, etc., with prominent eye symptoms, including conjunctivitis, eyelid edema, increased tears, photophobia, and an obvious horizontal line of congestion on the edge of the lower eyelid, which are extremely helpful in diagnosing measles. 2-3 days into the disease, the cheek mucosa becomes rough with varying numbers of grayish-white spots and surrounding red spots, which often merge and disappear within 2-3 days. Some cases may have some non-specific symptoms, such as general discomfort, loss of appetite, lack of energy, etc. Infants may have digestive system symptoms, vomiting, diarrhea, etc.
