Rotavirus disease in young children from Hanoi, Vietnam.

Background: Pathogen prevalences and antimicrobial susceptibilities are essential for the rational development of preventive strategies for diarrheal diseases, but little recent information from Vietnam is available. We prospectively studied the prevalence of enteric pathogens in children less than 5 years of age with acute diarrhea and in nondiarrhea controls in a city hospital in Hanoi, Vietnam for 1 year.

Methods: Enteric bacteria and viruses were detected by standard culture methods, and enzyme immunoassay in 291 cases and 291 controls.
