WHAT IS ROTAVIRUS ANTIGEN TEST?
Rotavirus is a sporadic, acute, infectious, diarrheal disease of the Reoviridae viral class in which five serigraphs have been identified. It replicates exclusively in the epithelial cells of the small intestine during the winter or cooler months. This virus is the major cause of sporadic acute enteritis in infants and of acute epidemic gastroenteritis in small children. Occurrence in the young is presumed to be caused by the absence of a well-developed immune system. Rotavirus is presumed to be transmitted by the faecal-oral route and is detectable only during the first 7-8 days of illness. Symptoms in children start with vomiting and progress to fever, diarrhoea, and abdominal cramping. Radioimmunoassay and complement-fixing antibody titers are used for rotavirus detection. Dominant genotypes include G1P (49%) and G2P (21%).
