Despite the remarkable achievements in the reduction of malaria mortality, the disease had remained the most common cause of morbidity and mortality. Infection with hepatitis B virus (HBV) and hepatitis C virus (HCV) might associate with increased mortality rate as the infections may predisposes to the development of serious liver diseases such as liver cirrhosis, liver failure and hepatocellular carcinoma (HCC). The aim of the present study was to determine the Asymptomatic Plasmodium falciparum co-infections with hepatitis B and C viruses among blood donors in Modakeke Area Office, Ile Ife, Osun State, Nigeria. The study was conducted in Modakeke Area Office, Ile Ife, Osun State. The study was conducted in Modakeke health facility, Ile Ife, Osun State. Five (5) ml of venous blood was obtained from each of 400 blood donors into plain bottles and labeled accordingly. Thick and thin films of the donor’s blood samples were made on slides dried for five minutes at 37°C then stained using Giemsa stain. The slides were then examined microscopically for presence and densities of malaria parasites. Species identification and determination of the Hematological parameters were also conducted on the slides. Sera were separated from the remaining aliquots of the blood and screened for hepatitis-B and C surface antigens (HBsAg and anti-HCV). The overall mean parasitaemia of malarious blood donors was 786.20µl/blood while that of blood donors with hepatitis virus infection was 53 representing 13.3% of the total donor examined. Donors infected with HBV, HCV and co-infection of HBV and HCV had viraemia of 25 (6.3%), 21 (5.3%) and 7(1.8%) respectively. Among the age groups, high prevalence of Hepatitis viral infection rate of 57.9% was recorded among aged group 18-26 years. The infection rate of 15.8%, 13.6% and 10.5% of HBV, HCV was recorded from age group 18-26years respectively. The highest co-infection rate of HBV and HCV of 18.8% was recorded from age group 54-62years, while high mean malaria parasitaemia of 1,882.78 (µl of blood) was also recorded among donors aged 18-26 years. High hepatitis viral infection rate of 22.2% with 16.7% of HCV were recorded among females, while 6.3% of HBV and 1.9% of co-infection was observed among males and the mean malaria parasitaemia of 2,382.80 µl of blood was observed among females. High prevalence of Hepatitis infection rate of 17.1%, 8.6% of HCV, (6.3%) of HBV and 2.3% of co-infection were recorded among single donors. The mean malaria parasitaemia of 786.89 (µl of blood) was observed among married donors, there was significant difference between marital status and hepatitis infection (p= 0.0043) and between HCV (p=0.009). High prevalence of hepatitis viraemia of 21.4% and co-infection 5.6% was recorded among artisans, while 14.6% HBV infection rate was recorded among civil servants and 14.3% of HCV was recorded among donors who are farmers. The mean malaria parasitaemia of 1,150.15 µl/blood was recorded among donors who are traders. Donors that have acquired primary education have high prevalence of hepatitis infection rate of 38.5%, with 15.4% of HBV and (23.1%) co-infection (HBVand HCV). HCV (6.7%) was high among donors with secondary education; high mean malaria parasitaemia of 2,096.84 µl of blood was recorded among donors with primary education. Blood B+ve had high hepatitis viral infection rate of 21.7%, HCV 13.0% and co-infection of 5.8% while 7.8% of HBV was recorded among O+ve donors. The mean malaria parasitaemia of 1,378.50 (µl of blood) was recorded among B-ve donors. The total mean PCV in the study was 42.63, White blood cell count was 5,281.25, lymphocytes count was 42.88, eosinophils was 1.53 and neutrophil count was 55.72. The total percentage of elevated AST was 5.0%, ALT was 6.0% and ALB was 10.5%. There was significant difference between malaria and ALT (p=0.000) also, there was significant difference between HCV and ALB (p=0.000). There was significant difference between HBV and AST (p=0.001), ALT (p=0.028) and ALB (p=0.028).The hepatitis viral infection had significant difference with ALB (p=0.000). The logistic regression shows that there was an association between hepatitis viral infection and aged group 27-35years (p=0.022), female (p=0.006), trading (p=0.001), tertiary (p=0.003) A+ve (p=0.018) and B+ve (p=0.001). In conclusion, Although, the prevalence of malaria was low, while that of hepatitis viral infection was high in the local government area, critical screening of blood donors is of prime importance because they serve as an asymptomatic reservoirs and a potential source of transmission of these infections. The strengthening of creating awareness on the general public regarding Malaria, HBV and HCV transmission and prevention should be embarked on.
