This is a discussion-based interactive seminar on the two major issues that affect Sub-Saharan Africa: HIV/AIDS and Poverty. AIDS and Poverty, seemingly different concepts, are more inter-related to each other in Africa than in any other continent. As MIT students, we feel it is important to engage ourselves in a dynamic discussion on the relation between the two - how to fight one and how to solve the other.

This module is intended to introduce students to one of the greatest social problems to face this planet, the global epidemic of HIV/AIDS and to increase their computer and research skills within sociology.

This patient education program explains Human Immunodeficiency Virus (HIV) infection and how that turns into AIDS. It stresses risk factors, screening, and prevention. This is a MedlinePlus Interactive Health Tutorial from the National Library of Medicine, designed and developed by the Patient Education Institute.

CD8+ cytotoxic T-lymphocytes (CTLs) perform a critical role in the immune control of viral infections, including those caused by human immunodeficiency virus type 1 (HIV-1) and hepatitis C virus (HCV). As a result, genetic variation at CTL epitopes is strongly influenced by host-specific selection for either escape from the immune response, or reversion due to the replicative costs of escape mutations in the absence of CTL recognition. Under strong CTL-mediated selection, codon positions within epitopes may immediately “toggle” in response to each host, such that genetic variation in the circulating virus population is shaped by rapid adaptation to immune variation in the host population. However, this hypothesis neglects the substantial genetic variation that accumulates in virus populations within hosts. Here, we evaluate this quantity for a large number of HIV-1– (n ≥ 3,000) and HCV-infected patients (n ≥ 2,600) by screening bulk RT-PCR sequences for sequencing “mixtures” (i.e., ambiguous nucleotides), which act as site-specific markers of genetic variation within each host. We find that nonsynonymous mixtures are abundant and significantly associated with codon positions under host-specific CTL selection, which should deplete within-host variation by driving the fixation of the favored variant. Using a simple model, we demonstrate that this apparently contradictory outcome can be explained by the transmission of unfavorable variants to new hosts before they are removed by selection, which occurs more frequently when selection and transmission occur on similar time scales. Consequently, the circulating virus population is shaped by the transmission rate and the disparity in selection intensities for escape or reversion as much as it is shaped by the immune diversity of the host population, with potentially serious implications for vaccine design.

Adult HIV was developed by doctors and nurses with wide experience in the care of adults with HIV, under the auspices of the Desmond Tutu HIV Foundation at the University of Cape Town. It covers: introduction to HIV infection, management of HIV-infected adults at primary-care clinics, preparing patients for antiretroviral (ARV) treatment, ARV drugs, starting and maintaining patients on ARV treatment, opportunistic infection. The aim of the book is to enable healthcare workers at primary-care clinics to manage all aspects of HIV-related patient care.

This resource is comprised of two companion components, the guide and the toolkit. The guide is intended to assist school leadership and management to understand why and how a particular strategy, method, or idea is useful, and not to be just a how to manual of tips. Yet the resource as a whole is at the same time intended to be relevant at all times to the context and practice of the school management team. Therefore, included in the toolkit component are realistic exemplars, check lists, and a set of information management tools that demonstrate approaches and methods for recording, planning, managing and monitoring implementation of a range of care and support interventions.
