Risk factors for human immunodeficiency virus infection among blood donors in Sao Paulo, Brazil, and their relevance to current donor deferral criteria

Abstract

A substantial number of HIV-infected donors reported a risk factor that could have been identified in the predonation screening. Male-male sexual behavior was still the strongest determinant of HIV status in the studied population.

Risk behavior disclosure among blood donors in Sao Paulo, Brazil

“…These results are in concordance with similar studies worldwide, showing that some high-risk donors are aware they undertake risky behavior, however, prefer to use blood donation as a means to learn whether they are infected with HIV or hepatitis B and C, although anonymous voluntary counseling centers are available (2-4) . Several factors are associated with this low compliance including the level of confidence between blood donors and physicians who performed clinical screening (3,5) age, gender, and education (6,7) which are also associated with low HIV/AIDS knowledge.…”

Which Infectious Blood Donors Could Be Identified by the Donor History Questionnaire - Comparison of Blood Donors Infected with HIV or HCV with Notified Cases from General Population in Germany

“…Comparison of risk factors among infected blood donors and infected individuals from the general population is only rarely used to assess the effectiveness of blood donor selection procedures. Risk factors for TTI and efficiency of donor selection are usually determined within the population of accepted donors [7,15,16]. However, we decided to use general population as an assessment reference for donor selection, since infected applicant donors are part of the general population but not part of the accepted donor population.…”

Syphilis and Blood Safety in Developing Countries

“…Donor deferral follows identification of any risk. Medical selection is crucial because it could permit to defer more than half of infected donors, especially the ones in the early period of infection here laboratory tests are not efficient (de Almeida Neto & al, 2007;Tagny, 2009). In some European countries, the prevalence of T. pallidum infection in the general population and thus in blood donors has been increasing since last two decades.…”
