“…The prevalence of positive serology for viral hepatitis found in this study is similar to those reported previously for Brazil by other authors (HBsAg: 0.14-0.78%, anti-HBc: 2.05-13.44%, anti-HCV: 0.34-1.14%) [46][47][48] . The prevalence of hepatitis B markers in Brazil varies greatly by region.…”

Introduction: Despite the great advances in serological testing for transfusion-transmitted infections, the selection of blood donors by blood bank operators remains the only way to avoid transmission within the testing window period. Part of this selection is the self-exclusion form, on which the donors can exclude their blood from donation without any explanation. This study assessed the clinical and epidemiological characteristics related to positivity for viral hepatitis and to the use of the confi dential self-exclusion (CSE) form. Methods: This transversal study analyzed the data collected from blood donors' fi les in a hospital in Southern Brazil. Univariate and multivariate analyses identifi ed the clinical and epidemiological variables related to positive serologies of viral hepatitis and to whether the donor was self-excluded. Results: Of the 3,180 donors included in this study, 0.1% tested positive for HBsAg, 2.1% for anti-HBc, and 0.9% for anti-HCV. When the 93 donors with positive serologies for viral hepatitis were compared with those who were negative, a greater proportion of the positive serology group was found to have had a history of blood transfusions (OR=4.908; 95%CI=1.628 -14.799; p<0.01), had repeatedly donated (OR=2.147; 95%CI=1.236 -3.729; p<0.01), and used the CSE form for self-exclusion (OR=7.139; 95%CI=2.045 -24.923; p<0.01). No variables were independently associated with self-exclusion. Conclusions: A history of blood transfusion, repeated donations, and self-exclusion are factors that should be considered during viral hepatitis screenings in blood banks.

“…More studies are needed to explore this area using different methods of data collection. In addition, toothbrushes, razors, and some other house-holding instruments can transmit HBV within the family (16). In our study, it was found that 8% of involved patients gave a positive family history of HBV infection.…”

Background: Infection with HBV is a major public health problem. Determining the risk factors of such an infection is of great importance for a preventive public health plan. Objectives: This study was conducted to determine the clinical presentations of patients with HBV, to assess the knowledge of patients about the mode of transmission of the infection, and to estimate the prevalence of risk factors associated with HBV infection. Methods: A cross-sectional study was performed among patients with HBV attending hepatitis unit in Azadi teaching hospital, Duhok city, Iraq. A total of 423 patients were recruited in the study over the period of January 2013 to December 2015. Data collection was performed by a face-to-face interview using a questionnaire sheet for the collection of personal information, data regarding the knowledge about mode of transmission of HBV, and data about risky behaviors. Results and Conclusions: 287/423 (68%) of the recruited subjects were males, 141/423 (33%) were from the central area in Duhok, and 216/423 (51%) were married. Additionally, 375/423 (88.7%) of the patients were asymptomatic. 383/423 (90.5%) of the recruited subjects claimed that they do not know the risk factors of HBV transmission. 85/423 (20.1%) of the recruited subjects gave a history of previous surgical operation and 73/423 (17.2%) of the patients gave a history of dental surgery. Conclusions: Our study has given an insight into the most common risk factors associated with HBV infection. Furthermore, it has shown a lack in knowledge regarding HBV. A comprehensive population based program is needed to combat the spread of infection and early detection of HBV infection especially in rural and remote areas.

“…Although several studies have been conducted on hepatitis B and C, especially on blood banks 6,7,8,9,10,11,12 , there are few studies carried out among the general population 13,14,15 , and due to territorial extension, and cultural and economic differences, the distribution of these diseases in the country differs among regions 16 .…”
