1.2 STATEMENT OF PROBLEM
What really instigated the study was the
prevalence of highly infectious diseases in Nigeria. the growth of
diseases in Nigeria and most African countries has increased overtime.
It is evident that researchers have put in so much effort to come out
with model on the effect of carriers on transmission dynamics of
infectious diseases but some prove abortive.
1.3 AIMS AND OBJECTIVES OF STUDY
The
main aim of the research work is to examine the modeling of the effect
of carriers on transmission dynamics of infectious diseases. Other
specific aims of the research work are:
1. To investigate the effects of carriers on the transmission dynamics
2. To determine the basic reproduction number and through numerical simulations
3. To investigate on the factors affecting the model
4. To proffer solution to the above model
1.4 RESEARCH QUESTIONS
The
study came up with research questions so as to be able to ascertain the
objectives of the study. The research questions are stated below as
follows:
1. What are the effects of carriers on the transmission dynamics?
2. How to determine the basic reproduction number and through numerical simulations?
3. What are the factors affecting the model?
1.5 SIGNIFICANCE OF STUDY
The
study on the modeling the effects of carriers on transmission dynamics
of infectious diseases will be of immense benefit the ministry of
health, hospitals, the state government and other researcher that wishes
to carryout similar research as the study will be able to discuss the
effects of carriers on the transmission dynamics and the factors
affecting the model
1.6 SCOPE OF STUDY
The study on modeling the
effects of carriers on transmission dynamics of infectious diseases is
limited to the modeling of selected infectious diseases like typhoid;
how they are transmitted and the model for their transmission.
1.7 DEFINITION OF TERMS
DISEASES:
is a particular abnormal condition, a disorder of a structure or
function that affects part or all of an organism. The study of disease
is called pathology which includes the causal study of etiology
CARRIERS:
individual harboring specific pathogenic organisms who, though often
immune to the agent harbored, may transmit the disease to others
INFECTIOUS: liable to be transmitted to people, organisms, etc. through the environment.
