“…The association between non-A, non-B hepatitis and acquaintance with another case of jaundice outside the household is suggestive of shared exposure to a common source of infection, like contaminated water, as in epidemic non-A, non-B hepatitis. Because contact with a jaundiced household member was also associated with non-A, non-B hepatitis, person-to-person transmission may be a factor as well [CDC, 1987bl. Previous reports have indicated that both epidemic and sporadic non-A, non-B hepatitis are common in nearby countries, and an outbreak of non-A, non-B hepatitis has been described in Sudan [Bassily et al, 1986;CDC, 1987a;Belabbes et al, 1985;Khuroo et al, 1983;Molinie et al, 1988;Nouasria et al, 1984;Shamma's, 1984;Zakaria et al, 19881. However, enterically transmitted non-A, non-B hepatitis has been noted to have a lower attack rate in children than in adults [CDC, 1987a,b;Khuroo, 1980;Belabbes et al, 19851. Delta hepatitis was not found to be a cause of acute hepatitis in this pediatric population, although it was diagnosed in 13% of adult hepatitis cases in a previous study [Al-Arabi et al, 19871.…”
