Sapovirus is a genus of viruses within the family Caliciviridae. These viruses are nonenveloped and have an icosahedral capsid composed of a single type of protein. The genome of Sapoviruses consists of single-stranded positive-sense RNA.1

Sapoviruses are a cause of gastroenteritis, an inflammation of the stomach and intestine characterized by diarrhea, vomiting, and abdominal cramps. While other viruses like rotaviruses and noroviruses are also common causes of viral gastroenteritis, Sapoviruses are recognized as a significant contributor to outbreaks of this illness.21
