Abstract
- PURPOSE
Respiratory viruses are one of the most infectious agent in human. Acute lower respiratory tract infection(ALRTIs) is associated with significant morbidity and mortality in children. This study is performed to investigate the etiologic organism, age and sex distribution, clinical manifestations and seasonal occurrence of ALRTIs in children.
METHODS
Viral agent was evaluated with nasopharyngeal aspirates, rhinorrhea and saliva collected from 568 patients. We confirmed viral agents in 54 patients who were younger than 15 year old. They had visited Maryknoll Hospital, Busan in Korea from January, 2002 to December, 2002 for ALRTIs.
RESULTS
The viral pathogens identified were Influenza A virus(59.3%), Enterovirus(33.3 %), Adenovirus(5.6%), and Influenza B virus(1.9%). Parainfluenza virus and Respiratory syncytial virus were not detected. The occurrence of acute lower respiratory infections was high between 3 & 6 years old. The clinical patterns include pneumonia(51.9%), bronchitis(31.5%), croup(9.3%), bronchiolitis(7.4%). The respiratory viral agents had their characteristic seasonal patterns.
CONCLUSION
Influenza A virus was the most common cause of acute lower respiratory tract infections in Busan area during the 2002. ALRTIs had high occurrence between 3 to 6 years old. And the most common clinical patterns were pneumonia and bronchitis.
