Rotavirus viral RNA electrophoresis in hospitalized infants with diarrhea in Santiago, Chile
Insights
Rotavirus was detected in 40% of young children with acute diarrhea in Chile. This viral gastroenteritis diagnosis was confirmed in 29.2% of all pediatric patients studied.
Area of Science:
- Virology
- Pediatrics
- Epidemiology
Background:
- Acute diarrhea is a significant health concern in infants and young children.
- Rotavirus is a common cause of severe gastroenteritis in pediatric populations worldwide.
- Understanding the prevalence and seasonality of rotavirus is crucial for public health interventions.
Purpose of the Study:
- To detect and quantify rotavirus infection in young children with acute diarrhea.
- To compare rotavirus prevalence in diarrheal cases versus healthy controls.
- To analyze the monthly distribution of rotavirus cases.
Main Methods:
- Viral RNA electrophoresis was employed for rotavirus detection.
- A cohort of 226 children under two years with acute diarrhea was studied.
- A control group of 25 healthy infants was included for comparison.
Main Results:
- Rotavirus was identified in 40% of diarrheal cases in winter and 0% in controls.
- Overall, rotavirus was diagnosed in 29.2% (66/226) of the pediatric patients.
- Monthly detection rates varied significantly, peaking at 83.3% in June and dropping to 11.1% in October.
Conclusions:
- Rotavirus is a prevalent pathogen causing acute diarrhea in young children in Santiago, Chile.
- The study highlights the significant burden of rotavirus gastroenteritis in this age group.
- Seasonal patterns of rotavirus infection were observed, with higher incidence during winter months.
Abstract:
Viral RNA electrophoresis technique was used to detect rotavirus in 226 children under 2 years of age with acute diarrhea, admitted to the Roberto del Río Hospital in Santiago, Chile, during the period of June 1979 through May 1980. A group of 50 children included in the aforementioned sample, admitted in winter, was compared with a control group of 25 infants without digestive pathology. In these groups, rotavirus was detected in 20 out of 50 children with diarrhea (40%) but not in the controls (0%). A positive diagnosis of rotavirus was found in 66 out of the total of 226 patients (29.2%); its monthly distribution ranged between a maximum of 83.3% (June) and a minimum of 11.1% (October).
