CALICI VIRUS INFECTIONS :CLINICAL ASPECTS
The incubation period is 10 to 51 hours, followed by abrupt onset of vomiting and diarrhea, a syndrome clinically indistinguishable from that caused by rotaviruses. Respiratory symptoms rarely coexist, and the duration of illness is relatively brief (usually 1–2 days). These viruses can be detected by electron microscopy or immunoelectron microscopy in stools during the acute phase of illness. In addition, EIA and PCR methods have been de-veloped. As with rotavirus infection, there is no specific treatment other than fluid and electrolyte replacement. Prevention requires good hygienic measures.
