Symptoms of Sapovirus
Sapoviruses cause a sporadic gastroenteritis, similar to norovirus, in populations ranging from children to the elderly. The infections are more frequent in children under age 5 than in adults. The most common symptoms of sapovirus are diarrhea, vomiting, nausea, and stomach pain. Other symptoms include fever, headache, and body ache.
Most people infected with sapovirus begin to develop symptoms 12 to 48 hours after infection. Symptoms usually last one to four days.
