Abstract
Purpose
: We evaluated the epidemiologic and clinical characteristics of mycoplasma pneumonia.
Methods
: A total of 559 medical records of children with mycoplasma pneumonia admitted to The Catholic University of Korea, Daejeon St. Mary's Hospital, were retrospectively analyzed.
Results
: The mean annual number of cases was 51. There was a higher occurrence in autumn (September-November, 41.7%) and in winter(26.7%). Outbreaks of mycoplasma pneumonia were noted in 1993-94, 1997, 2001, and 2003. The age distribution showed a peak frequency of 5-6 years of age and 68.2 percent of patients were in 3-8 years of age. The male-to-female ratio was 1.2 : 1. In comparison between 1994 and 2003, there was a difference in age distribution with a peak frequency of 5-6 years of age in 1994, and of 3-4 years of age in 2003. There were outbreaks during autumn and winter in 1993-94, and during summer and autumn in 2003.
Conclusion
: Outbreaks of mycoplasma pneumonia occurred every 2-4 years in Daejeon in accordance with nationwide epidemics during 1993-2003. The peak incidence of age in the recent outbreak was younger than in the outbreak which occurred 10 years ago, and in outbreaks in Western countries.
