Socio-Demographic Characteristics and Blood Parasites Among Blood Donors in Two Communities in Delta State, Nigeria

Abstract

A six months' study was conducted to determine the occurrence of blood parasites in blood donors in Eku and Abraka, Delta State. Random sampling was adopted for blood samples collection alongside socio-demographic characteristics. Laboratory analysis using thick and thin films were carried out on samples. The result showed that 59(29.5%) were positive for blood parasites; 46(23.0%) for Plasmodium, 5(5.0%) for Trypanosoma, and 8(4.0%) for microfilaria. Parasite prevalence was highest in the age-group 45-49 years. Female showed relatively higher prevalence (30.6%) compared to male (29.3%). There was no significant difference in blood parasites prevalence based on gender of the subjects. Blood group B had the dominant prevalence (51.7%). With respect to occupation, self-employed donors had higher prevalence (38.9%). In addition, the rural-urban prevalence was skewed towards rural blood donors (39.7%) with no statistical difference, in respect to residence.  PCV of donors showed no clear patterns and there was no association between PCV and prevalence of blood parasites (p>0.05). The results therefore indicate that there is relatively high prevalence of blood parasites among the blood donors which call for the attention of the authority concerned.
