Abstract
Purpose
: Rotavirus infection is a leading cause of severe gastroenteritis among infants and young children worldwide. In temperate regions, institutional outbreaks of the disease occur mainly in cold dry weather, whereas in tropical settings its seasonal course is less well defined. We studied the annual changes in the seasonal prevalence of rotavirus infection for 5 years.
Methods
: The study was conducted on 502 patients who lived in Taejon city and its vicinity. They were diagnosed with rotavirus gastroenteritis by stool latex coagulation method in Eulji Medical College Hospital from July 1993 to June 1998.
Results
: During the 5-years period, 502 fecal specimens were positive by rotavirus latex coagulation method. The peak of the infection occurred in 1994(July 1994-June 1995), 152 cases (30.3%) from July 1994 to June 1995 and the next peak occurred in 111 cases(22.1%) from July 1993 to June 1994. The seasonal peaks of the infection occurred in December 1993(17.1%) and January 1994(21.1%) and in March 1996(23.4%) and March 1997(22.5%).
Conclusion
: We observed that the seasonal peak in rotavirus infection changed over a 5-year period. The timing of rotavirus activity peaked during December-January(1993 and 1994), Februray-March(1996), and March-April(1997).
