“…The syndrome of nonbacterial gastroenteritis in small children may well be due to a similar agent, and adenoviruses and enteroviruses have been isolated from such patients; however, parallel studies of unaffected children show similar viruses in similar frequencies and these are apparently, in most cases, "passengers" also. Our results confirm those of Reimann et al (1945), Gordon et al (1947), Jordan et al (1953, Adler andZickl (1969), andDolin et al (1971), that faeces may contain viral agents which cause gastroenteritis in volunteers, but this is the first demonstration of such an agent in Britain, and the second in a school outbreak. It is noteworthy that the essential features of the epidemic disease-that is, the short incubation period and the presence of vomiting, diarrhoea, and low fever-were all reproduced in volunteers.…”
