“…According to an epidemiological survey conducted by the Korea National Research Institute of Health, the incidence of mycoplasma infection increased in 2007, with a subsequent upsurge between 2010 and 2011 [ 9 ]. MP is associated with diverse radiological findings, including concomitant pleural effusion and lobar pneumonia, which makes its differential diagnosis from bacterial pneumonia difficult merely based on clinical presentations and chest radiographs [ 20 , 21 ]. Further, it is not uncommon for M. pneumoniae infection to coexist with infections from other pathogens [ 22 ].…”

“…The PCV7 was introduced in Korea in November 2003, with the PCV10 and PCV13 introduced in June 2010 as an optional. In May 2014, PCV10 and PCV13 were incorporated in the national immunization program in Korea [ 21 ]. With regard to the immunization rate achieved, about 40% of the candidates for vaccination are estimated to have received the PCV7 as of 2007 [ 15 ].…”

PurposeUnderstanding changes in pathogen and pneumonia prevalence among pediatric pneumonia patients is important for the prevention of infectious diseases.MethodsWe retrospectively analyzed data of children younger than 18 years diagnosed with pneumonia at 117 Emergency Departments in Korea between 2007 and 2014.ResultsOver the study period, 329,380 pediatric cases of pneumonia were identified. The most frequent age group was 1–3 years old (48.6%) and the next was less than 12 months of age (17.4%). Based on International Classification of Diseases, 10th revision diagnostic codes, confirmed cases of viral pneumonia comprised 8.4% of all cases, pneumonia due to Mycoplasma pneumoniae comprised 3.8% and confirmed cases of bacterial pneumonia 1.3%. The prevalence of confirmed bacterial pneumonia decreased from 3.07% in 2007 and 4.01% in 2008 to 0.65% in 2014. The yearly rate of pneumococcal pneumonia also decreased from 0.47% in 2007 to 0.08% in 2014. A periodic prevalence of M. pneumoniae pneumonia (MP) was identified.ConclusionThe increased number of patients with pneumonia, bacterial pneumonia, pleural effusion, and empyema in 2011 and 2013–2014 resulted from an MP epidemic. We provide evidence that the frequency of confirmed cases of bacterial pneumonia and pneumococcal pneumonia has declined from 2007 to 2014, which can simultaneously reflect the effectiveness of the pneumococcal conjugate vaccine.
