The objective of this work was to compare three methods for estimating hepatitis B virus (HBV) incidence and residual risk. <jats:italic>Methods<\/jats:italic>. Computerized blood donor records in southern Brazil were examined for the period 2004\u20132006. The methods for estimating HBV incidence included stand-alone HBsAg, HBsAg yield method, and an extension of the latter which added recent anti-HBc seroconversions as incident HBV cases. <jats:italic>Results<\/jats:italic>. HBV incidences for the above methods were 9.91, 20.09, and 22.93 per 100000 repeat donors, respectively. In the same order, corresponding residual risks were 1\u2009:\u200962482, 1\u2009:\u200930821, and 1\u2009:\u200947559, respectively. First-time donors had 52 higher HBV incidence compared to repeat donors. <jats:italic>Conclusion<\/jats:italic>. Although the three methods compared produced overlapping 95% confidence intervals, their variation was considerably lower for the method which included recent anti-HBc seroconversions. First-time donors are primary cause for concern regarding HBV transmission via blood transfusion in southern Brazil.<\/jats:p>","DOI":"10.4061\/2011\/985383","type":"journal-article","created":{"date-parts":[[2011,7,7]],"date-time":"2011-07-07T13:38:54Z","timestamp":1310045934000},"page":"1-8","source":"Crossref","is-referenced-by-count":4,"title":["Comparison of Epidemiological Methods for Estimation of Hepatitis B Incidence and Residual Risk for Blood Donors in Southern Brazil"],"prefix":"10.1155","volume":"2011","author":[{"given":"Emil","family":"Kupek","sequence":"first","affiliation":[{"name":"Departamento de Sa\u00fade P\u00fablica\/CCS, Universidade Federal de Santa Catarina, 88040-900 Florianopolis, SC, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrea","family":"Petry","sequence":"additional","affiliation":[{"name":"Hematology and Hemotherapy Center of Santa Catarina (HEMOSC), Florianopolis, SC, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"key":"3","year":"1994"},{"issue":"3","key":"4","first-page":"165","volume":"12","year":"2003","journal-title":"Epidemiologia e Servi\u00e7os de Sa\u00fade"},{"issue":"5","key":"5","doi-asserted-by":"crossref","first-page":"462","DOI":"10.1590\/S0037-86822006000500008","volume":"39","year":"2006","journal-title":"Revista da Sociedade Brasileira de Medicina Tropical"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1079\/BER2006420"},{"key":"7","volume-title":"Minist\u00e9rio da Sa\u00fade.
