Trichinosis in Southeast Asian refugees in the United States

Abstract

Between 1975 and 1984, the incidence of trichinosis in the United States (per million person years at risk) was 25 times greater for the Southeast Asian refugee population than for the general United States population. Cases in the southeast Asian refugees differed from those reported previously in the general population in geographic distribution and source of infected meat. Cambodians and Laotians accounted for over 90 per cent of the cases in the Southeast Asian refugees, but comprised less than 50 per cent of that total population.
