National Cancer Institute Experience in Healthy Egyptian Blood Donors as Regards Blood Group Frequencies and Seroprevalence of Hepatitis B Virus, Hepatitis C Virus&HIV: 10 Year Evaluation.

Abstract

Decreasing prevalence of HBV, HCV & HIV among healthy non-paid volunteer donors over the last 5 years is mostly due to multiple hypothetical factors including; larger sample size due to increased donors recruitment efforts leading to more accurate results, and improvements in specificity and sensitivity of blood-borne pathogen detection. Paid donors, constituting a donor category during the preceding 5 years; were no longer accepted for donation as per Ministry of Health regulations. Lastly, the widespread utilization of Hepatitis B vaccination which is a mandatory vaccination according to Ministry of Health regulations and improved public heath awareness, shared in decreasing prevalence of HBV. The relatively higher socioeconomic classes showed lowest prevalence of viral markers, thus it should be targeted by donors recruitment plans. ABO blood group order of relative frequencies were found to be A+ve, O+ve, B+ve, AB+ve, A-ve, O-ve, B-ve, followed by AB-ve. Key Words: HBV , HCV , HIV , Blood group.
