Human rotaviruses (HRV) are a common cause of acute nonbacterial gastroenteritis in pediatric patients. A prospective study of HRV disease in a temperate (Dallas) and a tropical (San Jose, Costa Rica) setting demonstrated differences in seasonal distribution. In both locales, HRV accounted for 50% to 60% of acute nonbacterial gastroenteritis episodes from December through February; this period corresponded to the cooler months of winter in Dallas and to the dry season in San Jose. During the rest of the observation year, the virus was not recovered from any Dallas patients, but was found in 30% to 40% of Costa Rican patients in every month but May. Signs, symptoms, and laboratory values suggest the small bowel as the major site of pathophysiology; mucosal disruption may occur in some cases.

The maternal and fetal outcomes of 50 pregnancies complicated by acute viral hepatitis were examined. Twenty (40%) cases were due to type B hepatitis virus. The clinical course of the maternal hepatitis was unaffected by the pregnant state. Maternal hepatitis (type B or nontype B) had no effect on the incidence of congenital malformations, stillbirths, abortions, or intrauterine malnutrition; it did increase the incidence of prematurity (type B 31.6%; nontype B 25%; overall 27.6%) over that seen in the general delivery population (10 to 11%). Eight mothers acquired acute type B hepatitis during the third trimester; two of their infants (25%) were found to be chronic asymptomatic carriers of hepatitis B surface antigen and to have mild, persistent elevations of SGOT for up to 45 months.
