Résumé
Little is known about hepatitis E virus (HEV) prevalence in South American countries. AntiHEV was studied in 1,773 subjects from 1,360 blood donors of 3 cities in Chile, 72 in health care workers, 241 inmates in state jails and in 100 Araucarian indians. Anti-HEV was detected in 109 out of 1,360 (8.0 percent) total donors (6.3 percent, 6.1 percent and 18.8 percent from the cities of Valdivia, Osorno and Puerto Montt respectively); 9 out of 72 (12.5 percent) health care workers; 18 out of 241 (7.5 percent) inmates and 17 out of 100 (17 percent) Araucarian indians. Prevalence of anti-HEV was not related to age and sex. Hepatitis E is an endemic infection in some population groups of Southern Chile, associated to environmental pollution, crowding and low socioeconomic level
