The disease obviously affects mortality, and it could indirectly affect fertility through behavioral changes such as condom use, number of partners, and so on, or by causing the death of men and women of childbearing age.

To help understand the potential effects of this epidemic, several different computer-based epidemic models have been developed.

They have been used for both developed and less developed countries LDCsespecially African countries. These modeling efforts have the potential to help health policymakers understand the dynamics of the epidemic, to forecast the burden of illness in the future, and to evaluate potential interventions.

In addition to the policy issues that this letter raises, the interchange also suggests that we must consider how to validate or otherwise assess the quality of model results, especially when they are necessarily based on many assumptions.

The chapter begins with a brief introduction to the epidemiology of AIDS in Africa, with a focus on aspects of the epidemic that must be incorporated in the models.

It then describes the main features of epidemic models developed Page Share Cite Suggested Citation: Some quantitative and qualitative results of these models for the African situation are described, and the major sources of uncertainty are addressed. The report summarizes the efforts of eight modeling teams to apply their models with a common set of assumptions and compares the results.

Reports of more recent modeling efforts are also referred to. HIV causes severe damage to the immune system, and the course of HIV disease usually spans several years. Some individuals develop an acute illness resembling mononucleosis several weeks or months after infection, but most infected persons have no other clinical signs or symptoms for years.

The first clinical symptoms are often nonspecific; they could include chronic diarrhea, weight loss, fever, and fatigue.

The clinical manifestations of AIDS in developing countries can be very different from those in developed countries because the background microbiological flora are different. The proportion of HIV-infected persons who ultimately develop AIDS is not known precisely because no cohorts have been followed for much more than a decade, but the proportion is usually assumed to be percent.

Cohort studies of HIV-infected adults in the United States suggest that about 15 to 20 percent develop AIDS within five years and about 50 percent develop it within ten years.

The data for Africa are limited, and the incubation period may be similar or shorter because Africans are typically exposed more frequently to a larger range of infectious agents.Most of these children live in sub-Saharan Africa and were infected by their HIV-positive mothers during pregnancy, childbirth or breastfeeding.
