Duration of sapovirus shedding by reverse transcription real-time polymerase chain reaction in 61 infections. Sixty-one sapovirus infections in 47 children were tested to determine the duration of viral shedding. The boxes represent the 25th percentile, median, and 75th percentile, and the whiskers show the minimum and maximum value of the duration of shedding in days. For 2 infections for which the child’s last available specimen was positive, we estimated the duration of shedding based on the date of the last positive sample (28.5 days and 41.5 days). There were 8 infections with a shedding period of 30 days or longer, 2 of which were symptomatic. Abbreviations: GI, genogroup I; GII, genogroup II; GIV, genogroup IV; GV, genogroup V.
