While remarkable gains in health have been achieved since the mid-20th century, these have been unequally distributed, and mortality and morbidity burdens in some regions remain enormous. Of the almost 10 million children under 5 years of age who died in 2006, only 100 000 died in industrialised...

Selection bias in HIV prevalence estimates occurs if non-participation in testing is correlated with HIV status. Longitudinal data suggests that individuals who know or suspect they are HIV positive are less likely to participate in testing in HIV surveys, in which case methods to correct for...

Heckman-type selection models have been used to control HIV prevalence estimates for selection bias when participation in HIV testing and HIV status are associated after controlling for observed variables. These models typically rely on the strong assumption that the error terms in the...

Systematic reviews of health systems research commonly limit studies for evidence synthesis to randomized controlled trials. However, well-conducted quasi-experimental studies can provide strong evidence for causal inference. With this article, we aim to stimulate and inform discussions on...

We quantify the impact of adult deaths on household economic wellbeing, using a large longitudinal dataset spanning more than a decade. Verbal autopsies allow us to distinguish AIDS mortality from that due to other causes. The timing of the lower socioeconomic status observed for households with...

Estimates of HIV prevalence are important for policy in order to establish the health status of a country's population, to evaluate the effectiveness of population-based interventions and campaigns, to identify the most at risk members of the population, and to target those most in need of...

In this chapter, we briefly review the overall system of global health governance and its evolution over the last decade, the emerging challenges it faces, its strengths and weaknesses, and how these strengths and weaknesses affect the system’s ability to address tropical diseases in the future.

Using a large longitudinal dataset, we quantify the impact of adult deaths on household economic wellbeing. The timing of lower socioeconomic status observed for households in which members die of AIDS suggests that the socioeconomic gradient in AIDS mortality is being driven primarily by poor...

Global Health Governance (GHG) comprises the means adopted to promote decision making on actions to protect and promote global health, along with the underlying architecture of global health institutions, initiatives, and actors that facilitate these means. GHG is a key factor influencing health...

This paper presents a framework for the health system with health workers at the core. We review existing health-system frameworks and the role they assign to health workers. Earlier frameworks either do not include health workers as a central feature of system functioning or treat them as one...
