Analysis of Serological Detection of Measles Cases in Guangzhou in 2001-2006

Objective To evaluate the status of measles serology surveillance and the epidemiological features of measles in Guangzhou.Method The epidemiology and laboratory results of the surveillance of the suspected measles cases during 2001-2006 were analyzed.Results A total of 7 064 suspected measles cases have been reported in five years,in which 4 498 measles cases were positive in IgM antibody and the positive rate was 63.67%.Measles cases were mainly children and young adults,and most of them had uncertain measles vaccine immunization history.The status of measles surveillance system was normal,and the level of measles antibody of native population was higher than that of floating population.Most outbreaks occurred in the floating population and it was the reason that the measles incidence was somewhat high in Guangzhou.Conclusion To speed up the process of measles control,it is important to carry out enhanced immunization among those in high risk to measles,and to enhance the construction of measles surveillance system as well as the measles laboratory network.
