BACKGROUND: To assess the potential health benefits of introducing new rotavirus (RV) vaccines, we estimated mortality from RV gastroenteritis in Bangladeshi children <5 years of age. METHODS: We examined data from ongoing diarrhea surveillance in a systematic 2% sample (4% until 1995) of patients visiting the International Centre for Diarrheal Disease Research, Bangladesh, Dhaka Hospital during 1993-2004 and all patients visiting the rural Matlab Hospital during 2000-2004. To estimate deaths from RV, we multiplied the proportion of diarrhea visits attributable to RV with 2004 estimates of diarrhea deaths in Bangladeshi children. RESULTS: At Dhaka Hospital, RV was detected in 33% of 18,300 children with diarrhea. The proportion of diarrhea attributable to RV nearly doubled during 2002-2004 compared with 1993-1995 (42% versus 22%, P < 0.001). At Matlab Hospital, RV was detected in 35% of 4597 children with diarrhea. At both sites, most RV cases were among children age 3-24 months and the number of cases peaked during the cool and dry months from December through February. Of the 325,600 deaths among children <5 years that occur each year, we estimated 5600 to 9400 (2-3%) were attributable to RV. Thus, between 1 in 390 and 1 in 660 children born in Bangladesh each year die of RV infection by age 5. CONCLUSIONS: These data clearly demonstrate the tremendous health burden of RV gastroenteritis. The increasing proportion of severe diarrhea cases underscores the need for specific interventions against RV, such as vaccines, to further reduce diarrhea mortality and morbidity.
