What symptom is measles?

(1) Mild measles virus infection with reduced virulence is more common in those who have received gamma globulin injection within the incubation period, or in infants less than 8 months old who still have maternal antibodies. Fever was low and upper respiratory symptoms were mild. The mucosal spot of measles is not obvious, and the rash is sparse. The course of disease was about 1 week without complications.

(2) Severe measles fever up to 40 ℃, severe poisoning symptoms, with convulsions, coma. Rash fusion was purple blue, often mucosal bleeding, such as epistaxis, hematemesis, hemoptysis, hematuria, thrombocytopenia, known as black measles. The rash is few, the color is dim, often for the circulation bad performance. The mortality of this type of children is high.

(3) No typical mucosal spots and rash were found in the patients who had been injected with live attenuated measles vaccine, and even no rash occurred in the whole course of the disease. The clinical diagnosis of this type is difficult, only depending on the precursor symptoms and the increase of measles antibody titer in serum.

matters needing attention

It can prevent measles by giving immunoglobulin immediately within 5 days after contact with measles; More than 6 days can not achieve the above effect. The patients who had used immunoglobulin had great changes in clinical process, long incubation period, atypical symptoms and signs, but they still had potential infectivity to the contacts. Passive immunization can only last for 8 weeks, and active immunization measures should be taken in the future.
