Objective: To determine the prevalence of viral haemoparasites in prospective Nigerian
blood donors.
Methods: Ethical clearance was obtained and informed consent questionnaires were
distributed to blood donors to obtain their demographical data. A total of 186 blood
donors from LAUTECH Teaching Hospital, Osogbo were tested for hepatitis A virus
(HAV), hepatitis B virus (HBV) and hepatitis C virus (HCV) using rapid test kit and
enzyme linked immunosorbent assay.
Results: The highest prevalence of blood transmitted infections was 182 (97.85%) while
the prevalence of HIV, HAV, HBV and HCV were 6.45%, 97.85%, 14.52% and 3.23%,
respectively. Highest seroprevalence for hepatitis A, B and C occurred among low risk
occupation. There was no significant association between all the hepatitis viruses and
demographic factors except occupation with P value of 0.002 7. Hepatitis A, B and C
seropositive blood donors on average tend to have PCV within the normal reference
range. Out of the 27 hepatitis B positive blood donors, 22 were donating blood for the
first time while 5 were repeat donors. None of the hepatitis C seropositive donors have
been exposed to blood or any form of its products and were all donating blood for the first
time. However, the distribution of donor type for HAV is random.
Conclusions: The prevalence of HAV, HBV, HCV and HIV among prospective donors
in Nigeria is alarming particularly HAV. These infections can be transmitted to recipients
if proper screening is not carried out, hence they should be included as a routine test for
blood donors.
