IMPACT OF AWARENESS DRIVEN BY MEDIA EFFORTS ON THE SPREAD OF HIV INFECTION
Nareshkumar C. Chavda, Sunita Gakkhar
Abstract
In this paper, a non-linear mathematical model is proposed to study the impact of awareness driven by media efforts on the dynamics of HIV. The awareness spread in the population is taken in two aspects self motivated and media driven. It is assumed thatdue to awareness of the disease some susceptible are becoming cautious or aware about the disease and start taking necessary precautionary actions to protect themselves while some people require encouragement or efforts to drive them towards followingthe necessary precautions. For such people who require to be driven on the way of awareness the media efforts are made to makelarger number of susceptible aware. Due to the awareness, susceptible are taking necessary care to remove the possibility to contact with HIV infected.A global qualitative analysis and numerical simulations are carried out to show that typical threshold behavior hold for the proposed non-linear compartmental model.
