The objectives of the GHiGS team are:

  • to produce data on diseases affecting the global south, their epidemiology, risk factors and consequences;
  • to use these findings to design and to evaluate innovative interventions at individual and population level, which are effective, but also equitable and sustainable, and contribute to the advancement of global health.

Per the definition of Koplan et al. (The Lancet 2009;373(9679):1993-5), global health is an area for study, research, and practice that places a priority on improving health and achieving equity in health for all people worldwide. Global health emphasizes transnational health issues, determinants, and solutions; involves many disciplines within and beyond the health sciences and promotes interdisciplinary collaboration; and is a synthesis of population-based prevention with individual-level clinical care.

Per the definition of the World Bank, the global south is made up of Africa, Latin America and the Caribbean, Pacific Islands, and the developing countries in Asia, including the Middle East.

Research areas

Scientific orientations of the research team

The GHiGS team aims to contribute to improving health at individual and population level in countries from the Global South and to contribute to reducing health inequities between countries, as well as within countries.

Low- and middle-income countries, and in particular in Sub-Saharan Africa, are going through major changes including epidemiologic, sociodemographic, economic, agronomic, technological, and climatic transitions. At the same time, they are carrying the triple burden of: (i) infectious diseases, including HIV, tuberculosis, malaria, hepatitis and a number of other emerging infectious disease threats (including hemorrhagic fevers and other epidemics); (ii) growingly prevalent non-communicable diseases (NCDs; diabetes, cancers, hypertension, obesity), and (iii) unprecedented outdoor pollutions and environmental threats. The GHiGS team aims to respond to these major transitions and new challenges through integrated, multi-level and inter-disciplinary research approaches in the context of the Global South.

Among the key highlights of the past five years, the GHiGS team contributed to a major revision in the international HIV treatment guidelines issued by the World Health Organization and was among the rare research teams worldwide having conducted a treatment trial to reduce mortality during the Ebola virus disease epidemic in West Africa.

In the coming years, the GHiGS team will strengthen and expand two key research themes, i.e. infectious diseases and mother and child health issues, to address new challenges in the field of diagnosis, care, and treatment and beyond.
