Abstract
This paper identified the risk factors for environmental health related diseases and formulated a fuzzy logic based predictive model based on the identified variables. Related literatures were reviewed so as to understand the body of knowledge surrounding environmental health related diseases and their corresponding risk factors, interviews with community health officers were conducted in order to validate the identified variables. Fuzzy logic was used to formulate the predictive model using Matlab Fuzzy logic tool box. Data was collected from five different states in Nigeria. The result showed that there are cases of environmental related diseases in the areas where there is no potable water and in locations that lack good toilet facilities. In the areas where there is no toilet facility or where bucket and bush are used as toilet, there are always cases of cholera. In these areas during the rainy season cholera outbreaks are common occurrences. All these points to fact that, if there is a good environmental health tracking system with predictive features, then environmental health officers would be able to easily monitor, manage and track any area which may be prone to any of these environmental health diseases.
Highlights
Environmental health related diseases are diseases that occur as a result of the poor conditions of the environment
Fuzzification is the first process in modelling a fuzzy logic system
The first step in the modelling of the controller is data fragmentation into input that can be accepted by fuzzy logic
Summary
Environmental health related diseases are diseases that occur as a result of the poor conditions of the environment. Epidemics which result from poor environmental conditions are common in developing nations, especially SSA nations [2]. The most prevalent among these environmental related diseases in the region include typhoid, cholera, malaria, diarrhoea and guinea worm. SSA region has the highest number of people living with these diseases worldwide [3]. According to Onwuliri [4], in developing nations, poor water supply, poor sanitation and hygiene tend to account for a large part of the burden of illness and death. Diarrhoea accounts for 4.3% of the total global disease burden and an estimated 88% of this burden is attributable to unsafe drinking water, inadequate sanitation and poor hygiene. Three hundred million people are estimated to suffer from malaria yearly [4]
