The human immunodeficiency virus (HIV) and its latter stage, the acquired immune deficiency syndrome (AIDS), are still a major health problem in the world and the full extent of the epidemic is unknown. The HIV virus in Australia has been spread mainly through homosexual contact, but this mode of transmission is decreasing while transmission from heterosexual contact and from IV drug use is increasing. The proposed mathematical model concentrates on transmission of the HIV virus through heterosexual contact and IV drug use among heterosexuals in Western Australia. The model parameters will be estimated from surveys conducted by the Australian National Injecting Drug Use Study 1989-1991. The estimated parameters will be incorporated into the developed model and used in conjunction with computer simulations to study the spread of HIV and its progression to AIDS in Western Australian heterosexuals
