Fecal specimens from patients with acute diarrhea were collected from 10 prefectures in Japan over a 6-month period (November 1992 to April 1993), and the specimens that were negative for human group A rotaviruses were screened for the presence of human group C rotaviruses (CHRVs) by the reverse passive hemagglutination test. Of 784 specimens examined, 53 samples (6.8%) that were collected in 7 of 10 prefectures were positive for CHRV, indicating that CHRVs are widely distributed across Japan. Most of the CHRV isolates were detected in March and April, and CHRVs mainly prevailed in children ages 3 to 8 years. The genome electropherotypes of eight strains isolated in five individual prefectures were surprisingly similar to each other and were different from those of CHRV strains isolated to date. The outer capsid glycoprotein (VP7) gene homologies of the isolates retrieved in 1993 were subsequently analyzed by the dot blot hybridization method. As a result, the VP7 genes of the isolates revealed very high levels of homology not only with each other but also with the VP7 gene of the OK118 strain isolated in 1988. These results suggest that a large-scale outbreak of CHRV occurred during the winter of 1992 and 1993 in Japan.

Generally, group A rotaviruses are the most common cause of paediatric diarrhoea. However, group B rotavirus, adult diarrhoea rotavirus (ADRV), was found to be involved in epidemics of severe gastroenteritis in several areas of China during 1982–1983 and had resulted in more than one million cases among adults as well as older children. Human group B rotavirus has been rarely reported outside China, but has been detected first from five adults with diarrhoea in Kolkata, India during 1997–1998 (strain CAL-1). During epidemiological studies at the National Institute of Virology (NIV) on hospitalized diarrhoea patients at Pune, India, faecal specimens from patients of >5 years age, which were negative for group A rotavirus by ELISA were tested by polyacrylamide gel electrophoresis (PAGE). We detected rotavirus RNA migration patterns similar to that of group B rotavirus in three faecal specimens from adults, two from the specimens collected in 1993 and one in 1998 from sporadic diarrhoea cases. RT–PCR was carried out using primers derived from gene 8 which codes for the NS2 protein, followed by nested PCR, which confirmed the presence of group B rotavirus in all three specimens. The sequences of the PCR products of NIV specimens were compared with that of CAL-1, ADRV and IDIR (infectious diarrhoea of infant rat) belonging to group B rotaviruses. The sequence analysis of the PCR products showed the highest identity with CAL-1, which was reported from Kolkata, India during 1997–1998. The finding suggests that human group B rotaviruses have been circulating in Pune, India, since 1993. This emerging virus may lead to more severe disease among adults in India. There is a need for surveillance of group B rotavirus infections, especially in adult diarrhoea cases and seroepidemiological studies on group B rotavirus are required among humans and animals of Western Maharashtra, India.
