MORE-YUPANQUI, Miryam Danitza et al. Prevalence of infection markers and associated factors in donors of a peruvian blood bank. Rev. perú. med. exp. salud publica [online]. 2021, vol.38, n.4, pp.627-633.  Epub Dec 20, 2021. ISSN 1726-4634.  http://dx.doi.org/10.17843/rpmesp.2021.384.9286.

We aimed to determine the prevalence of infection markers in donors of a Peruvian blood bank and to assess whether donor sociodemographic variables are associated with the presence of these markers. An analytical cross-sectional study was carried out in 5942 donors of a blood bank, whose data was collected during 2018. Positivity to human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV) and HTLV I-II was determined, in addition to syphilis and Chagas disease. The prevalence of HIV was 0.81%; for HBV it was 6.19%; for HCV, 0.12%; for HTLV I-II, 0.66%; for Chagas disease, 2.76% and for syphilis it was 1.73%. Several sociodemographic factors were associated with infection markers positivity. The predominant donation type was non-voluntary (96%) and 53% had history of previous donation. The prevalence of infection markers for HIV, HBV, Chagas disease and syphilis in blood donors was high compared to other countries in the region.
