ABSTRACT
In a prospective-descriptive epidemiological study it is informed that in eutrophic
children from 3 months to 5 years of age, with a clinical diagnosis of acute infectious
gastroenteritis (GA), from 1
st of January to the 30
th of June of
2002, ambulatory and hospitalized for secondary dehydration.
Objectives:
Investigate the annual frequency and the monthly incidence, in ambulatory and hospitalized
patients with GA caused by human rotavirus (RVH). The incidence of RVH in patients younger
than 2 years of age hospitalized, and the sever ness of GA in hospitalized children with a
dehydration degree of 10% more than there admittance in 67 patients (7%) all younger age
two years.
Material and methods: 3,295 children with infectious GA were studied;
2,345 (71%) external, and 950 (29%) hospitalized with GA for secondary dehydration.
RVH was identified in excretions by monoclonal antibody (rotatest kit).
Results
: In four years (1999-2002) in 2,345 external patients with GA, RVH was identified in 789
samples (33.6%). In 950 hospitalized children the result was positive in 402 (42.32%). The
annual frequency of RVH in 3,295 ambulatory and hospitalized children with GA was positive
in 1,191 excretion samples (36.15%). The higher monthly incidence in both groups was in
winter. In 402 children with GA-RVH hospitalized for secondary dehydration; 350 children
(87%) were younger than 2 years of age. The highest severity estimated by the degree of
dehydration at their admittance was: severe 10% or more in 67 children (7%) all of them
younger than 2 years of age. There were no demises. Conclusions: We didn’t observe in four
years any variations in the annual frequency of GA-RVH in ambulatory and hospitalized
patients of less than 5 years of age. The incidence for GA-RVH is higher in winter in
children of less than 2 years old. The severity for dehydration occurs in children of less
than 2 years old. The clinical antecedent of GA-RVH was investigated in all the cases of
hospitalized patients, and the result was negative. A prevalent seropositive type is
possible.
