Objective To diagnose scientifically suspected measles cases.Method ELISA was used to test all serum samples. Results 187 serum samples from suspected measles cases were tested. The positive rate of IgM of measles was 45.5%. Highest positive rate of 52.6% was observed in the age group of 2～6 years of 52.6% . 19 samples were tested IgM antibody of rubella. The positive rate was 20.1%. The result showed that some of suspected measles cases were actually rubella cases. 21.2% of positive cases had no immunization history of measles vaccine.Conclusion The suspected measles cases couldn't be diagnosed solely by clinic symptoms.
