Host-Vector-Parasite Relationship Among Inhabitants Of The Anambra River Basin Irrigation Project Area

A questionnaire survey was employed to identify the sources of contact with parasites and disease vectors among people living in the Anambra River Basin Irrigation Project Area. The survey indicated that more than half of the inhabitants of this area go to farm. While in the farm disease vectors such as mosquitoes, biting midges, snails and tsetse flies are usually encountered. In addition, the lack of proper sewage disposal common among the communities exacerbates the situation. Water from various sources such as rivers, ponds, streams, as well as rainwater are used for many purposes. Common disease symptoms such as diarrhoea, abdominal pain, blood in sputum, body nodules, blood in stool, coughing, itching, headache, fever, haematuria were commonly recorded. Positive relationships were observed between the presence of some vectors and the corresponding disease symptoms.
