Abstract:
A community based study was realized from 1996 to 1998 on 400 school children in An Phu district (an outbreak occurred in 1994) and Tan chau district (control district), An Giang province. After 3 years of follow up the results showed that the HEV prevalence in school children was not a high. Prevalence of HEV infection was 21.6% (in An Phu) and 8% (in Tan Chau). Sero-conversion rate in An Phu and in Tan Chau after 1 year of follow-up was 0.7% and 1.2%, and after 2 years was 5.1% and 1.9% respectively. Prevalence of HEV infection of family members of HEV(+) school-children was 14.7%, while this prevalence of HEV(-) school-children was 5.9% living together in the same household might be one of risk factors for HEV transmission. Against a background of low anti-HEV prevalence, and low sero-conversion in an area of previous outbreak occurrence, the potential of epidemic transmission among a 'succeptible population' remains high, particularly in flooding season
