Responding to the AIDS epidemic in Angola

South African Centre for Epidemiological Modelling and Analysis (SACEMA), Stellenbosch, South Africa Correspondence to [email protected] Summary The epidemic of HIV in Angola started later and stabilized at lower levels than in most countries in southern Africa. Some studies suggest that certain high risk groups account for a substantial part of the total number of infections. With ...

AIDS Epidemic Modeling With Different Demographic Structures

The most urgent public health problem today is to devise effective strategies to minimize the destruction caused by the AIDS epidemic. Mathematical models based on the underlying transmission mechanisms of the AIDS virus can help the medical/scientific community understand and anticipate its spread in different populations and evaluate the potential effectiveness of different approaches for bri...

An epidemic model for the transmission dynamics of HIV/AIDS with different clinical stages

In this paper, a five–dimensional mathematical model is proposed for the transmission dynamics of HIV/AIDS within a population of varying size. In writing the model, we have divided the population under consideration into five sub classes of susceptible, infective, pre-AIDS, AIDS related complex and that of AIDS patients. The model has two non- negative equilibria namely, a disease free and the...

HIV/AIDS situation in Africa.

The HIV/AIDS pandemic marks a severe development crisis in Africa, which remains by far the worst affected region in the world. Forty-two million people now live with HIV/AIDS of which 29.4 million (70.0%) are from sub-Saharan Africa. Approximately 5 million new infections occurred in 2002 and 3.5 million (70.0%) of these were also from sub-Saharan Africa. The estimated number of children orpha...
