Abstract

Fecal viral concentrations of 40 patients infected with norovirus genogroup GII.4 correlated with diarrhea duration and frequency of vomiting. Higher viral concentration and older age were independently associated with prolonged diarrhea (> or =4 days). These findings provide information on the pathogenesis and transmission of norovirus infections.

Box plot of median (black horizontal bars) and interquartile range (error bars) of fecal norovirus cDNA concentrations in patients with limited and prolonged diarrhea. Limited diarrhea is defined as a total duration of diarrhea of 1–3 days, and prolonged diarrhea is defined as a total duration of diarrhea ≥4 days.
