title: Rotavirus infections in families. A clinical and virological study.
abstract: Among 25 family members of 8 children with acute rotavirus gastroenteritis (8 siblings and 17 adults) gastroenteritis was recorded in 9 (5 siblings and 4 adults), and minor symptoms in 8 (2 siblings and 6 adults). A rotavirus infection was diagnosed in 7 of the family members with gastroenteritis and was probably the cause of the disease in the remaining 2 in this group. Four of the 8 family members with minor symptoms were infected with rotavirus, whereas no infection was detected among the 8 family members without symptoms. Serological findings sugggested that infants and young children underwent a primary infection with rotavirus, whereas older children and adults probably were reinfected. Adults as well as children with rotavirus infection excreted virus and may have served as sources of infection.
