Insights
Human caliciviruses (HuCVs) are a significant cause of severe childhood gastroenteritis in Peru. Studies show HuCVs were more prevalent in sick children than in healthy controls, indicating their role in illness.
Area of Science:
- Pediatric Gastroenterology
- Virology
- Public Health
Background:
- Gastroenteritis is a leading cause of childhood illness globally.
- The specific role of human caliciviruses (HuCVs) in severe pediatric gastroenteritis requires further definition.
Purpose of the Study:
- To investigate the prevalence and role of HuCVs in Peruvian children hospitalized with severe gastroenteritis.
Main Methods:
- Fecal and serum samples were collected from 233 hospitalized children with gastroenteritis (case patients) and 248 healthy children (control subjects).
- HuCV infection was detected using fecal and serological testing.
Main Results:
- Human calicivirus infection was detected in 55% of case patients, significantly higher than in control subjects (35% vs. 13%).
- HuCV infection was more common in children with gastroenteritis without other identified pathogens (77%) compared to those with coinfections (49%).
Conclusions:
- Human caliciviruses are a significant etiological agent in severe gastroenteritis among Peruvian children.
- HuCVs play a crucial role in pediatric gastroenteritis, particularly in cases without other identifiable infectious agents.
Abstract:
To define the role of human caliciviruses (HuCVs) in severe childhood gastroenteritis, fecal and paired serum samples from 233 Peruvian children hospitalized with gastroenteritis (case patients) and fecal samples from 248 control subjects were evaluated. Overall, 128 case patients (55%) demonstrated HuCV infection by either fecal (n=81 [35%]) or serological (n=96 [41%]) testing. HuCVs were more prevalent in fecal samples from case patients than those from control subjects (35% vs. 13%; P<.001). HuCV infection was more prevalent among case patients without another pathogen than in those who had a coinfecting pathogen (77% [40/52] vs. 49% [88/181]; P<.001). HuCVs appear to be an important cause of gastroenteritis in Peruvian children.
