Insights
Community-acquired pneumonia (CAP) remains a major global health threat in children. Continuous surveillance of respiratory pathogens, including emerging viruses like SARS-CoV-2, is crucial for effective treatment and vaccine development.
Area of Science:
- Pediatrics
- Infectious Diseases
- Epidemiology
Background:
- Community-acquired pneumonia (CAP) is a leading cause of childhood hospitalization and mortality globally.
- While immunizations have reduced bacterial pneumonia, respiratory viruses, including SARS-CoV-2, remain significant pathogens.
- Emerging infectious agents necessitate ongoing investigation into CAP epidemiology and causative agents.
Purpose of the Study:
- To investigate the epidemiology of CAP in children.
- To identify causative pathogens, including Streptococcus pneumoniae serotypes and Mycoplasma pneumoniae mutations.
- To inform antibiotic use and guide future vaccine development through pathogen surveillance.
Main Methods:
- A study by the Pneumonia and Respiratory Disease Study Group in Korea investigated CAP pathogens in hospitalized children.
- Analysis included Streptococcus pneumoniae serotyping and Mycoplasma pneumoniae gene mutation prevalence.
- Antibiotic resistance patterns and serotype data were assessed.
Main Results:
- Data on causative pathogens, Streptococcus pneumoniae serotypes, and Mycoplasma pneumoniae prevalence were gathered.
- Antibiotic resistance and serotype information were obtained to guide empirical antibiotic treatment.
- Findings contribute to understanding pathogen changes and prevalence for vaccine development.
Conclusions:
- Continuous national surveillance of respiratory pathogens is essential for monitoring CAP epidemiology.
- Surveillance aids in managing antibiotic resistance and developing effective vaccines.
- Monitoring helps track emerging infectious diseases like SARS-CoV-2.
Abstract:
Community-acquired pneumonia (CAP) is the single largest infectious cause of hospitalization and death in children worldwide. With improved immunizations, the incidence of bacterial pneumonia and the number of colonized bacteria have decreased. However, respiratory viruses are still an important cause of CAP, especially as new infectious agents such severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerge. The SARS-CoV-2 virus emerged in 2019 and caused the current coronavirus disease 2019 pandemic. Therefore, it is necessary to elucidate the epidemiology and causative pathogens of CAP. Recently, the Pneumonia and Respiratory Disease Study Group, affiliated with the Korean Academy of Pediatric Allergy and Respiratory Disease, investigated the causative pathogens of respiratory infections in children hospitalized with CAP, the serotype of Streptococcus pneumoniae, and the prevalence of Mycoplasma pneumoniae with gene mutations. Antibiotic resistance and serotype test results can determine the use of empirical antibiotics. Moreover, it is possible to help develop future vaccines by comparing bacterial culture results with vaccine serotype and identifying the changes and prevalence of each serotype. Therefore, we will perform continuous national surveillance and monitor the epidemiology of respiratory pathogens in Korea and worldwide. The surveillance of these respiratory infections can play a role in monitoring the emergence of new infectious diseases such as SARS-CoV-2.
