The etiology of bacterial pneumonia and meningitis in Vietnam

Abstract

Hib is the most frequent cause of meningitis in infants and children admitted to hospitals in South Vietnam. Ninety percent of Hib meningitis cases occur in patients < 1 year of age. Bacteremic Hib pneumonia in Vietnam is rare. The results suggest that Hib is the major cause of meningitis in Vietnam but do not permit conclusions regarding its true incidence. The carrier rate of Hib in children <5 years of age in Vietnam has increased to approximately 7% since 1993.
