Analysis on Serum IgM Antibody Detection Among 219 Cases of Suspected Measles

Objective To accurately identify the rash of measles and other diseases,and timely grasp the situa- tion of measles epidemic.Methods 219 cases of suspected measles undergoing IgM antibody detection were statistically analyzed in Ganzi Tibetan Autonomous Prefecture in 2005-2007,by the use of theChina immu- nization programs monitoring management information systemsand Microsoft Excel software.Results Among serum of the 219 suspected cases of measles,175 were detected as measles IgM antibody positive,and the positive rate was 80.00 %.Among the 44 serum with measles IgM antibody-negative,IgM antibodies were detected for rubella.20 positive cases were found,and the positive rate was 45.45%;there was no statistical significance in positive rate of measles IgM antibody among all age groups;the rate of measles vaccination a- mong patients with rash was only 9.59%;and there were also 66.67% of them unknown the vaccination rate.
