Abstract
Alcoholism is a serious problem in Kenya today and many adults are addicted to
alcohol. The harmful use of alcohol causes a large burden concerning diseases, social
and economic problems to the society. Mass media campaigns against alcohol
act as sources of information to halt alcohol abuse and its potentially harmful effects.
In this research, we developed deterministic models for alcohol abuse driven
by the light and heavy drinkers taking into consideration the influence of pre exposure
to mass media campaigns. Two models were developed, one with perfect
pre exposure campaigns where the campaigns were successful and the other with
imperfect pre exposure campaigns where the campaigns were not successful. The
two models were analyzed through the determination of the model’s steady states
and their respective stabilities analysis in terms of the alcohol abuse reproduction
numbers R0. The analysis shows that alcohol-free equilibrium (AFE) is locally
asymptotically stable if R0 < 1 and unstable if R0 > 1. Numerical simulations
were carried out and the sensitivity analysis of the model parameters was done
to determine where the campaigns should be targeted for effective control of the
abuse. The results from the simulations illustrated that increasing the rate of
treatment reduces the number of alcohol addicts in the community. The results
also showed that mass media campaign against alcohol consumption reduces alcohol
abuse. From the study we conclude that if alcohol treatment is emphasized
and mass media campaign regulated then alcohol addiction will be reduced from
the community.
