Sapovirus (Genogroups I, II, IV, and V). Sapovirus is a Calciviridae family member that is similar to Norovirus both genetically and in disease presentation. There are five genogroups (GI–GV); groups GI, GII, GIV, and GV are known to infect humans, whereas GIII causes diarrheal illness in pigs. Sapovirus causes disease mostly in children, though adults are susceptible as well, with outbreaks reported in long-term care facilities, prisons, cruise ships, and hospitals in the USand EU.58,59 Like Norovirus, Sapovirus is spread via the fecal-oral route and infections are highest during winter months. Symptoms primarily include vomiting and diarrhea with nausea and fever lasting 5 to 10 days.60,61 In general, illness is self-limiting with treatment consisting of supportive care. Infections are attributed to an estimated 15,000 foodborne illnesses in the US annually,12 however the true incidence may be much higher as there is very limited testing available.
