Abstract:
Objective To investigate the epidemiological characteristics of children infected by mycoplasma pneumoniae(MP)over the last five years in Kunming region.Methods Indirect immunofluorescence assay was used to detect blood MP-IgM of hospitalized patients from January 2003 to December 2007 in order to determine the age and gender distribution characteristics of MP infection and to investigate the epidemiological features of the five years' results.Results Infection incidences by MP in Kunming region over the last five years were 20.9%,14.3%,17.5%,15.7%and 19.5%,respectively.Statistical significance was found among the groups mentioned above(P＜0.01).The MP infection incidences in different age groups were 10.7%(～1 year old),20.5%(～3 years' old),21.5%(～6 years' old)and 21.7%(～14 years' old).MP infection incidences showed age and gender characteristics(P＜0.01).Infants showed lower NIP infection incidence and infection incidence was higher in female.The epidemiological investigation indicated that MP infection incidences varied from year to year(P＜0.01).The infection incidences of 2003 and 2007 by MP were higher than those of the other years.There were epidemiological differences in infection incidences by NIP over last five years(summer,autumn and winter).The MP infection incidences showed seasonal differences(P＜0.01).Conclusion Mycoplasma pneumoniae was the main local causative agent responsible for respiratory tract infection in children aged under one years' old in Kunming region.Over the last five years,there were two outbreaks in the local area,but with no seasonal regularity of epidemiology.
