Insights
Group A rotavirus caused acute diarrhea in Paraguayan children, peaking in winter. The infection was most common in infants aged 6-23 months, with two dominant rotavirus strains identified.
Area of Science:
- Pediatrics
- Virology
- Infectious Diseases
Background:
- Group A rotavirus is a leading cause of severe diarrheal disease in infants and young children globally.
- Understanding regional rotavirus epidemiology is crucial for public health interventions and vaccine strategies.
Purpose of the Study:
- To investigate the prevalence and characteristics of Group A rotavirus infections in children with acute diarrhea in Asunción, Paraguay.
- To identify common rotavirus strains and their association with age and season.
Main Methods:
- Fecal samples were collected from 410 children with acute diarrhea admitted to hospitals in Asunción between August 1998 and August 2000.
- Group A rotavirus was detected using molecular methods.
- Rotavirus electropherotypes were analyzed to determine strain diversity.
Main Results:
- Group A rotavirus was detected in 93 (22.7%) of the 410 fecal samples.
- Infections were most frequent during the winter season and in children aged 6 to 23 months.
- Ten distinct rotavirus electropherotypes were identified, with two predominant strains; Rotavirus subgroup I showed minimal involvement.
Conclusions:
- Group A rotavirus is a significant cause of acute diarrhea in young children in Asunción, Paraguay.
- The findings highlight the seasonal patterns and age distribution of rotavirus infections in the region.
- Dominant rotavirus strains identified may inform local public health surveillance and vaccine efficacy studies.
Abstract:
Group A rotavirus infections were detected in 93 of 410 fecal samples from children with acute diarrhea, admitted in three main hospitals of Asunción, Paraguay, from August 1998 to August 2000. Most of the rotavirus-infected patients were admitted during the winter season in the three epidemic years. The rotavirus infection rate was highest in infants from 6 to 23 months of age. In the 93 samples examined, 10 different rotavirus electropherotypes were recognized, but two of them largely predominated. Only one sample showed a short electropherotype pattern, thus indicating a minor involvement of the rotavirus subgroup I in rotaviral acute diarrhea in the area and the time during which the survey was carried out.
