ABSTRACT
This research work focused on development of an expert system for COVID-19 diagnosis using Jim Van Medical Complex as a case study. the study was necessary because of the existing problems such as few medical personnel are available for handling COVID-19 diagnosis, the manual process is time consuming, high cost of diagnosis of COVID-19 medically, in view of these, the objectives of the study are to implement an expert system to diagnose COVID-19 based on input symptoms in absence of medical personnel, to create a system that will reduce the cost of diagnosing COVID-19, to implement a system that will facilitate proper record keeping of COVID-19 diagnosis records and to implement a system to retrieve COVID-19 diagnosis reports. The significance of the study is that it will help reduce the workload on medical experts in the diagnosis of COVID-19, it will help in increasing the number of diagnosis of COVID-19 since it can be used by end users independent of a medical personnel, and it will help curb the spread of COVID-19 as diagnosed patients w\ill seek for treatment. The software development methodology used is Object Oriented Analysis and Design Methodology (OOADM). The programming language used is Visual BASIC 6.0 and the database used is Microsoft Access.
