| Abstract |
|
Asymptomatic human rotavirus (HRV) infection rate was studied by comparing the rate of HRV
excretion in diarrhea cases with that in nondiarhea group of children under preschool age. HRV
antigen in stool was detected by enzyme-linked immunosorbent assay (ELISA) from children under 6
years of age who were admitted to Pediatric Department of Chung-Ang University Medical Center
from November 1988 to mid-April 1989.
1) HRV antigen was detected in stools of 49 patients (57.6%) among 85 patients with diarrhea
(diarrhea group) and 42 patients (37.2%) among 113 patients without diarrhea (nondiarrhea group).
2) HRV excretion in stool associated with diarrhea was observed in 25% of neonates, 58.3% of
l-to-6-month-old patients, 74.4% of 7-to-24-month-old patients, and 50% of 25-month-to-6-year-old
patients.
3) HRV excretion in stool not associated with diarrhea was observed in 48.1% of neonates, 35.3%
of l-to-6-month-old patients, 44.1% of 7-to-24-month-old patients, and 22.9% of 25-month to 6-year-
old patients.
4) Asymptomatic infection rate of HRV was 46.2% (42/91).
5) Symptomatic infection rate of HRV was 53.8% (49/91).
6) Asymptomatic HRV infections developed in 76.5% of neonates, 46.2% of 1 to 6 months age
group, 34.1% of 7 to 24 months age group, and 47.1% of 25 months to 6 years age group of HRV
infected patients.
7) There were significant differences in age distribution of asymptomatic and symptomatic HRV
infection. In neonates, asymptomatic infections were more frequent than symptomatic infections. In
7 to 24 months age group, symptomatic infections were more frequent than asymptomatic infections. |
