ABSTRACT
One thousand six hundred people belonging to three different occupational groups were randomly selected. Blood, urine and stool specimens were collected from them and processed for the detection of any parasitic infections. The results show 28.5% infection rate with one or more species of intestinal parasites; 50.7% in the school children, 17.3% among the farmers, and 12% among the soldiers. Results of blood examination showed 5.3%, 8.0% and 2.0% infection rates for P. falciparum in the school pupils, farmers and soldiers respectively, while 31.3% of the three groups were infected with the microfilaria of Dipetalonema perstans, and Loa loa. These were found in 60.7% of the farmers and none at all in the other two groups. Urine examination yielded no positive cases of urinary schistosomiasis and only one case of Trichomonas vaginalis. These results reflect the endemicity of the respective parasites, the degree of their sanitary awareness and their exposure frequencies to the pathogens as a result of their daily activities.
