Abstract:
PURPOSES: To investigate the viral etiology of community-acquired pneumonia in Korean adults, we have detected respiratory viruses (Respiatory syncytial virus, adenovirus, influenza virus and parainfluenza virus) in the way of prospective, multi-center study. METHODS: From July 1997 to April 2000, nasal aspirates or sputum were obtained from adults patients with community pneumonia admitted to the participating hospitals and transferred immediately to the central laboratory in the Seoul National University Children's Hospital. The specimens were divided into three parts. One part was used for indirect immunofluorescent test for respiratory viruses, the other part for the culture of RSV and adenovirus in HEp-2 cell monolayer. Another part was used for the culture of influenza virus and parainfluenza virus in MDCK or LLC- MK2 cell monolayers. RESULTS: Of 317 samples, 32 (10.1%) specimens were positive for viral isolation by indirect IF staining or culture, including one dual-infected specimen (adenovirus and parainfluenza virus). Influenza virus was most commonly detected (16 specimens). Parainfluenza virus, adenovirus and RSV were detected in 10, 4 and 3 patients, respectively. All isolated influenza viruses were type A (H3N2 in 9 patients, H1N1 in 2 and unspecified in 5), and 8 out of 10 parainfluenza virus isolates were type 3. CONCLUSION: Similar to previous foreign reports, a significant portion of community-acquired pneumonia in Korean adult is caused by respiratory viruses. Our data empathized the need of referral system for viral diagnosis and of nationwide investigation on respiratory virus infections.
