The increasing prevalence of HIV/AIDS in Africa over the past twenty-five years continues to erode the continent's health care and overall welfare. There have been
various responses to the pandemic, led by Uganda, which has had the greatest
success in combating the disease. Part of Uganda's success has been attributed to
a formalized information, education, and communication (IEC) strategy, lowering
estimated HIV/AIDS infection rates from 18.5% in 1995 to 4.1% in 2003. We
formulate a model to investigate the effects of information and education campaigns
on the HIV epidemic in Uganda. These campaigns affect people's behavior and
can divide the susceptibles class into subclasses with different infectivity rates.
Our model is a system of ordinary differential equations and we use data about the
epidemics and the number of organizations involved in the campaigns to estimate
the model parameters. We compare our model with three types of susceptibles to
a standard SIR model.

Abstract
The increasing prevalence of HIV/AIDS in Africa over the past twenty-five years continues to erode the continent's health care and overall welfare. There have been
various responses to the pandemic, led by Uganda, which has had the greatest
success in combating the disease. Part of Uganda's success has been attributed to
a formalized information, education, and communication (IEC) strategy, lowering
estimated HIV/AIDS infection rates from 18.5% in 1995 to 4.1% in 2003. We
formulate a model to investigate the effects of information and education campaigns
on the HIV epidemic in Uganda. These campaigns affect people's behavior and
can divide the susceptibles class into subclasses with different infectivity rates.
Our model is a system of ordinary differential equations and we use data about the
epidemics and the number of organizations involved in the campaigns to estimate
the model parameters. We compare our model with three types of susceptibles to
a standard SIR model.
