We screened 303 Hispanic pregnant women who were migrant or seasonal agricultural workers in Oregon for the presence of Hepatitis B serological markers. One carrier was identified (0.3 per cent, 95% confidence interval [CI] .02%, 2.1%). Evidence of previous HB infection was present in 5.3 per cent (16/303) of the women (95% CI 3.2%, 8.6%), rates similar to those for the general US population.
