Malaria and hookworm co-infection and their effects on anaemia of pregnant women attending ante-natal clinic in University Teaching Hospital, Calabar, Nigeria.

Background: Malaria and hookworm infections independently have been known to cause anaemia. Coinfection of these two parasites can aggravated the morbidity of these infections with a resulting impact on anaemia especially in pregnancy. Aims and Objective: This work was aimed at assessing the prevalence of malaria and hookworm co-infection and their effects on anaemia among pregnant women in Calabar Metroplis. Materials and Methods: Giemsa stained film of venous blood was examined microscopically for malaria parasites while cyanmethaemoglobin method was used for haemoglobin level estimation. Stool samples were examined microscopically while Stoll's technique was used in counting the ova of hookworm. Results: 19(6.3%) of the subjects were infected with hookworm, 45(15.0%) with malaria, while 9(3.0%) were infected with both parasites. Severe anaemia of 4(44.4%) was observed amongst the test (infected) subjects while the control (uninfected) subjects had a severe anaemia of 3(1.0%). The highest prevalence of co-infections of malaria and hookworm 4(38.6%) occurred among the age group of 26-30years (p=0.371). Subjects in their 3rd trimester had the highest prevalence of co-infection of 4(4.4%) (p=0.412). The highest prevalence of severe anaemia 1(100.0%) occurred among the age group of 16-20years (p=0.002). Conclusion: This work has shown a low prevalence of malaria and hookworm co-infection. The level of severe anaemia among infected pregnant women was more than that observed among subjects without any of the two infections. [ABSTRACT FROM AUTHOR]
