Malaria parasitemia and its severity have been associated with many host attributes including ABO blood groups. Using cross-sectional study design, six hundred and twenty five (625) respondents were randomly selected from three senatorial districts of Imo State. Structured questionnaire and laboratory diagnosis were the tools used in eliciting the information needed for the study. Data were subjected to descriptive statistics, analysis of variance (ANOVA) and Chi-square using SPSS statistics version 23. Therespondents were dominated by male 331(53%) youths who were within the age range of 31-40 years 152(24%) and were mostly residing in the urban area 100(16%). They had primary school education 219(35%) as their highest level of education. Almosthalf of them belong to O blood group 296(47%). Laboratory diagnosis showed that out of the 625 participants, malaria parasitemia was high in 395(64%) respondents especially in the rural area 203(32.5%). Besides, Owerri zone 173(28%) had more malaria subjects than other senatorial zones with significant association (p = 0.018). Plasmodiumfaciparium was the major parasitemia suffered by the subjects 358(90%). Most of the subjects 246(62%) had low malaria parasitemia. Blood group had significant influence on malaria parasitemia such that participants belonging to O blood group 187(47%) had more malaria. Efforts should be made by government in improving access to health care in malaria endemic states as this will help to reduce the malaria parasitemia.
