Prodromal phase also known as pre eruption, generally 3-4 days. The symptoms were similar to those of upper respiratory tract infection: (1) fever was seen in all cases, most of which were above moderate fever; ② Cough, runny nose, tears, pharyngeal congestion and so on, with eye symptoms prominent, conjunctival inflammation, eyelid edema, increased tears, photophobia, lower eyelid edge has an obvious congestion line (Stimson line), is very helpful for the diagnosis of measles. ③ The mucosal spots of measles appeared 24-48 hours before the eruption, with a diameter of about 1.0 mm and a red halo outside. At first, they only appeared on the buccal mucosa facing the lower molar, but they increased rapidly within one day, and could involve the whole buccal mucosa and spread to the lip mucosa. The mucosal rash disappeared gradually after the eruption, and there were dark red spots; ④ Urticaria, macular rash or scarlet fever like rash were occasionally seen, which disappeared when typical rash appeared; ⑤ Some cases may have some nonspecific symptoms, such as general discomfort, loss of appetite, and mental depression. But the temperature dropped slightly. Infants may have digestive symptoms, vomiting, diarrhea, etc.

Measles pathological changes of appendiceal mucosa can cause appendicitis symptoms. Delirium, irritability and drowsiness often occur in the extreme stage of the disease, especially in high fever. Most of them are transient. The fever subsides and disappears, which has nothing to do with the complications of the central nervous system. At this stage, there was moist rale in the lung, and X-ray examination showed increased lung markings.
