Question
How can a three-year-old boy with no apparent reason for a high fever show symptoms of measles? What was the previous treatment situation and outcome? What are the symptoms of measles?
Answer
The typical clinical presentation is divided into three stages: the prodromal phase, the rash phase, and the recovery phase (desquamation phase). Each phase lasts about 3 days, totaling approximately 9-12 days. ① The prodromal phase: characterized by fever, with body temperature often between 38-39°C, accompanied by symptoms such as membrane congestion, photophobia, lacrimation, hiccups, and cough, which are upper respiratory catarrhal symptoms. ② The rash phase: typically, the rash begins to appear on the 4th or 5th day after the onset of fever. ③ The recovery phase: after the rash has fully appeared and penetrated, body temperature begins to rise and falls back to normal within 1-2 days, and the overall condition stabilizes.
