Seroprevalence of Hepatitis B Virus among Blood Donors at National Blood Transfusion and Research Center-Taiz Branch, Yemen

Hepatitis B Virus (HBV) represents one of the most health problems. Almost more than 350 million infected persons were reported universally. Blood transfusion is commonly the most common route of transmission of HBV. Recently, Hospitals in Yemen are increasing demands for blood and blood products due to war injury, anemia, and malnutrition. The risk of transfusion transmission of infection relatively increases. This study aimed to determine hepatitis B virus prevalence among blood donors at the National Blood Transfusion Center -Taiz branch (NBTRC- TB). Data was collected from the National Blood Transfusion and Research Center (Taiz branch) from 1/4/2020 to 16/12/2020. A total of 3174 blood donors donated blood at the center. A descriptive cross-sectional study was conducted on them. Blood donor information was registered at the reception department, and all blood screening tests were performed. Data of HBsAg and total anti-HBc were analyzed statistically by using IBM SPSS version 26. Among 3174 blood donors, male blood donors were 3158 (99.5%) and female blood donors 16 (0.5%). Furthermore, 41 (1.3%) were positive for HBsAg (which all the positive results were for male donors and no positivity were for female donors) while 353 (11.1%) were positive for total anti- HBc Ab which is distributed at ratio of 11% (350) for males and 0.1% (3) for females. On the other hand, the result of HBsAg and total anti-HBc Ab together showed three levels of positivity as the (HBsAg positive / anti-HBc negative) were 12 (0.4%) in which was a low percentage and reversely, the (HBsAg negative/ HBcAb positive) were 316 (10.2%), While the HBsAg positive / anti-HBc positive were 27 (0.9%). So this study shed light on the result of HBsAg negative/ anti-HBc positive which the percentage (10.2%) of which statistically significant (p. value = 0.000) and was the highest result indicates donors with post HBV infection or have low HBV infection. This study showed the high prevalence of post-HBV infection among blood donors. Using both markers HBsAg and total anti-HBc Ab will improve the detection of HBV before blood transfusion.
