Key result

The overall prevalence of human caliciviruses in HIV-seropositive children was 19%, with remarkable genetic diversity and no statistically significant difference in detection rates between children with and without diarrhoea (24.3% vs 16.2%, p=0.3130).

Population

105 HIV-seropositive children <14 years of age, 37 with diarrhea and 68 without diarrhea, from a children's…

Implication

Similar detection rates suggest limited diagnostic value for diarrhea in HIV-seropositive children; leaves open calicivirus pathogenicity and requires longitudinal studies.

105 HIV-seropositive children under 14 years of age (mean 6.3 years), with or without diarrhoea, from a children's home and home-based program in Kenya.

Prevalence and genotype diversity of human caliciviruses (norovirus and sapovirus)

Main Result

Absolute Event Rate: 24.3% vs 16.2%

p-value: p=0.3130

Human caliciviruses, particularly diverse norovirus and sapovirus genotypes, are prevalent in HIV-seropositive children in Kenya, with similar detection rates in symptomatic and asymptomatic individuals.

Limitations

  • Small sample size
  • No defined diarrhoea-free period prior to specimen collection for asymptomatic cases
  • Lack of data on bacterial or parasitic infections to exclude them as causes for diarrhoeal symptoms
  • No defined diarrhea-free period prior to specimen collection
  • No data on bacterial or parasitic infections

Cite This Study

Mans et al. (2013) conducted a cross-sectional in HIV infection (n=105). Human calicivirus infection was evaluated on Detection of human caliciviruses in children with diarrhoea versus without diarrhoea (p=0.3130). The overall prevalence of human caliciviruses in HIV-seropositive children was 19%, with remarkable genetic diversity and no statistically significant difference in detection rates between children with and without diarrhoea (24.3% vs 16.2%, p=0.3130).
