CHAPTER ONE: INTRODUCTION

 1.1 Background to the Study

With the advancement of information technology, computer is considered to be one of the most powerful tools for information dissemination and creating awareness.

In like manner, developing a system to represent the repository of the knowledge of a medical doctor is as essential as any other system.  To this end, this project, on the awareness of Lassa fever diseases is a necessity.

Lassa fever is an acute viral illness that occurs in West Africa. The illness was discovered in 1969 when two missionary nurses died in Nigeria. The virus is named after the town in Nigeria where the first cases occurred. Lassa fever is endemic in parts of west Africa including Sierra Leone, Liberia, Guinea and Nigeria; however, other neighboring countries are also at risk, as the animal vector for Lassa virus, the "multimammate rat" (Mastomysnatalensis) is distributed throughout the region.

           The advantage of this system is to give awareness on Lassa fever, since it is one of the disease that people are having problems with because of fear of stigmatization and it was noticed that human relate freely with computers than a human expert, this System should be made available for people so that it will serve the doctors as help and also means of awareness on the disease.

The Project is intended to use computer programs to develop a system that creates awareness and give more information on sign and symptom as well as cure process, furthermore it will serve as a preventive measure and give a platform to user to contacting doctor t which will provide adequate knowledge on the disease.

1.2 Problem Statement

Lassa fever is a serious disease that could claim millions of life, with the increase in spread of disease that has being recorded become a threat or danger to the entire human race; due to lack of information and awareness that are not in place for the masses, which can be through online information and awareness system that were not available, these lead to the risk of outbreak and re-outbreak of the diseases. It’s a key issue that, there is need for urgent solution as medical personnel and general public might be affected during or before reaching medical centers and put all at risk of infection of the disease.

1.3 Aim and Objectives

The aim of this project is to build an Interactive system that help doctors and other users by creating crucial information and awareness on the impact of Lassa fever to humanity.

The objectives are:

a)     Obtain an appropriate knowledge about the Lassa fever.

b)     Design of a Database (knowledge base) for retrieval of knowledge obtained above and other BIO Data.

c)     Design of a diagnostic interaction medium and user interface.

d)     Synchronization of each module to interact internally within the system.

1.4 Scope and Limitation

a.    The system focused and response only on Lassa diseases

b.    An interactive medium design for user.

c.    A dynamic database system that can act as a knowledge based system.

 1.5 Significant of the study    

a.     It will help to retain the skill of medical doctor in case of any eventuality.

b.      It can support academic development.

c.      It can be useful in many hospitals, both private and government.

d.      It can also serve as first aid to patient for emergency issue.

1.6 Methodology

The following Steps is taken in order to meet the objective of this work:

a.      Literatures review on the subject matter and related works.

b.     A database is designed to make information retrieval easy.

c.      A data collected direct from interview with medical doctors as well as surfing the internet which form the knowledge store of the expert system.

d.     MYSQL is a platform for the database.

e.      PHP is used as the server side scripting language to implement the functionality of the system

f.      JavaScript is used to add functionalities.

g.     Bootstrap is used for fine CSS interfaces.

h.     Wamp/Xamp are the apache web servers used for the system
