Abstract

This study was performed to monitor the causative agent of patient with respiratory disease in Pusan, 1998-1999. The results obtained were as follows. Among 1,320 cases of specimens from throat swab, influenzavirus infections were detected 232(89.6%), adenovirus infections were in 14(5.4%), coxsackievirus infections were in 11(4.2%), and echovirus infections were in 2(0.8%). The 222 strains out of 232 strains of influenzavirus showed A-type and the rest of them represented B-type. The distribution for sex- and age-groups is as follows. The male distribution was similar to the female distribution: male distribution, 47.1% and female distribution, 52.9%. Most of the patients was less than 10 years old. The monthly influenza distribution was consistent from Dec. 1998 to Apr. 1999. The 113 strains from the A-type isolates was A/Sydney/05/97(H3N2)-like, the 109 strains A/Beijing/262/95(H1N1)-like, and all of the 10 B-type isolates B/Harbin/07/94-like. Electron micrograph of negative-stained showed about 95 nm and about 71 nm with influenzavirus and adenovirus, respectively. Coxsackievirus and echovirus showed non-enveloped, isometric particle of about 30 nm diameter.
