The present study examined the association of specific virus
infections with acute respiratory tract conditions among hospitalized and outpatient children in a subtropical country. A total of 2,295 virus infections were detected in 6,986 patients between 1997 and 1999, including infections caused by respiratory syncytial virus (RSV)
(1.7%), parainfluenza virus (2.0%), influenza B virus (2.6%),
adenovirus (4.0%), herpes simplex virus type 1 (4.4%), influenza A
virus (5.5%), and enterovirus (12.7%). There were 61 mixed
infections, and no consistent seasonal variation was found. One or more
viruses were detected among 24.8% of hospitalized patients and 35.0%
of outpatients. The frequencies and profiles of detection of various
viruses among in- and outpatients were different. The occurrence of
enterovirus infections exceeded that of other viral infections detected
in 1998 and 1999 due to outbreaks of enterovirus 71 and coxsackievirus
A10. RSV was the most prevalent virus detected among hospitalized
children, whereas influenza virus was the most frequently isolated
virus in the outpatient group. Most respiratory viral infections
(39.3%) occurred in children between 1 and 3 years old. RSV
(P < 0.025) and influenza A virus (P < 0.05) infections were dominant in the male inpatient group. In
addition, most pneumonia and bronchiolitis (48.4%) was caused by RSV
among hospitalized children less than 6 months old. Adenovirus was the
most common agent associated with pharyngitis and tonsilitis (45.5%).
These data expand our understanding of the etiology of acute
respiratory tract viral infections among in- and outpatients in a
subtropical country and may contribute to the prevention and control of
viral respiratory tract infections.
