Norovirus and other stomach viruses in young South African children

Gastroenteritis virus infections in South African children: secretor status-linkedsusceptibility, prevalence and genetic diversity and humoral responses to norovirusinfection

NIH-funded research University of Pretoria · NIH-11403895

This project will track which stomach viruses (norovirus, rotavirus, and adenovirus) infect children under five in South Africa and when babies develop protective antibodies.

What this research studies

If your child is admitted to a participating hospital with gastroenteritis, samples will be collected to see which viruses are causing illness. The team will also test wastewater from 11 treatment plants across South Africa to find viruses circulating in the community. Scientists will sequence virus genomes to learn which strains are common or emerging and use a protein microarray to measure antibodies in infants, including dried blood spots from HIV-exposed babies. The work follows children in age groups from birth to two years over five years to learn when protective immunity appears.

Who could benefit from this research

Good fit: Ideal participants are children under five hospitalized with gastroenteritis in South Africa and infants (birth to 2 years), including HIV-exposed babies whose dried blood spots are available.

Not a fit: Adults, children without gastroenteritis symptoms, or people living outside the participating areas of South Africa are unlikely to benefit directly or take part.

Why it matters

Potential benefit: Results could help doctors and public health teams better prevent and respond to stomach-virus outbreaks and guide vaccine or prevention strategies for young children.

How similar studies have performed: Surveillance and genome sequencing have successfully tracked enteric viruses before, though combining hospital cases, nationwide wastewater data, and infant antibody microarrays is less common and relatively new.
