Invited Review: PDF OnlyThe Epidemiology of Rotavirus Infections A Global PerspectiveHaffejee, Ismail E.Author Information Department of Paediatrics & Child Health, Faculty of Medicine, University of Natal, Durban, South Africa Journal of Pediatric Gastroenterology and Nutrition: April 1995 - Volume 20 - Issue 3 - p 275-286 Free Abstract Rotavirus, which is the most common cause of infantile diarrhea worldwide, mainly affects infants between the ages of 6 and 24 months. Most infections in human newborns are mild or asymptomatic, due to the inherently attenuated nature of the “nursery” rotavirus strains. Adults are also sometimes affected, especially those in families with an infected child; the disease also occurs in closed adult communities, HIV-infected persons, travelers, or as a result of water-borne epidemics. Nosocomially acquired hospital infections add to morbidity and to the cost of hospitalization. A winter predominance of rotavirus diarrhea has been noted in temperate climates but not in tropical areas. Group A rotavirus infections are generally more common, but human infections with groups B and C have also been documented. The prevalence of scrum antibodies is high during the neonatal period, but it declines sharply between the ages of 3 and 6 months, then rises steeply, peaking at 2 years and remaining high into adulthood.
