[Clinical features of Japanese children infected with Cryptosporidium parvum during a massive outbreak caused by contaminated water supply].
A massive outbreak of cryptosporidiosis occurred at a local town of Saitama Prefecture, in 1996. During this outbreak, we investigated the clinical features of children seen at Saitama Medical School. Cryptosporidium parvum (C. parvum) was detected from 10 out of 28 (36%) children with diarrhea during June and August, 1996. The average ages of the children who were positive and negative for C. parvum were 6.5 and 5 year old, respectively. Among the children infected with C. parvum, colic pain was observed in 3 children and 4 children had vomiting. However, none of the children showed fever over 38.0 degrees C nor bloody stools. Family members of children infected with C. parvum also had diarrhea and/or vomiting (5/6). C. parvum was repeatedly detected from 2 out of 3 children. All infected children had an improvement of abdominal symptoms in 4 to 10 days. C. parvum should be included as a pathogen which causes enterocolitis in Japanese children.
