Hypothesis

Can infectious rotavirus be detected in the blood of children with rotavirus antigenemia?

Conclusion

Most children infected with rotavirus are viremic, and the presence of viremia is related to antigenemia, independent of diarrhea.

Supporting Evidence

  • 90% of children with rotavirus-positive stools had detectable antigenemia.
  • Infectious virus was found in 100% of antigen-positive sera.
  • Antigenemia was present in children without diarrhea.

Takeaway

This study found that many kids with rotavirus have the virus in their blood, not just in their poop, which might explain why they can get sick in other ways.

Methodology

Serum samples from children with gastroenteritis were tested for rotavirus antigen using enzyme immunoassay, and infectious virus was detected through serial passages in cell culture.

Potential Biases

Potential bias in sample selection as only hospitalized children were included.

Limitations

The study may not represent all children with rotavirus infections, as it focused on hospitalized children.

Participant Demographics

Children with gastroenteritis, including those with rotavirus-positive and negative stools, and healthy adults.
