The contribution of international health volunteers to the health workforce in sub-Saharan Africa.

BACKGROUND: In this paper, we aim to quantify the contribution of international health volunteers to the health workforce in sub-Saharan Africa and to explore the perceptions of health service managers regarding these volunteers. METHODS: Rapid survey among organizations sending international health volunteers and group discussions with experienced medical officers from sub-Saharan African countries. RESULTS: We contacted 13 volunteer organizations having more than 10 full-time equivalent international health volunteers in sub-Saharan Africa and estimated that they employed together 2072 full-time equivalent international health volunteers in 2005. The numbers sent by secular non-governmental organizations (NGOs) is growing, while the number sent by development NGOs, including faith-based organizations, is mostly decreasing. The cost is estimated at between US$36,000 and US$50,000 per expatriate volunteer per year. There are trends towards more employment of international health volunteers from low-income countries and of national medical staff.Country experts express more negative views about international health volunteers than positive ones. They see them as increasingly paradoxical in view of the existence of urban unemployed doctors and nurses in most countries. Creating conditions for employment and training of national staff is strongly favoured as an alternative. Only in exceptional circumstances is sending international health volunteers viewed as a defendable temporary measure. CONCLUSION: We estimate that not more than 5000 full-time equivalent international health volunteers were working in sub-Saharan Africa in 2005, of which not more than 1500 were doctors. A distinction should be made between (1) secular medical humanitarian NGOs, (2) development NGOs, and (3) volunteer organizations, as Voluntary Service Overseas (VSO) and United Nations volunteers (UNV). They have different views, undergo different trends and are differently appreciated by government officials.International health volunteers contribute relatively small numbers to the health workforce in sub-Saharan Africa, and it seems unlikely that they will do more in the future. In areas where they play a role, their contribution to service delivery is sometimes very significant.

Intersectoral collaboration between the medical and veterinary professions in low-resource societies: The role of research and training institutions.

BACKGROUND: Neglected zoonoses continue to significantly affect human health in low-resource countries. A symposium was organised in Antwerp, Belgium, on 5 November 2010 to evaluate how intersectoral collaboration among educational and research institutions could improve the situation. RESULTS: Brucellosis and echinococcosis were presented as models for intersectoral collaboration. Low-resource societies face evident knowledge gaps on disease distribution, transmission within and across species and impact on human and animal health, precluding the development of integrated control strategies. RECOMMENDATIONS: While veterinarians have been the main driver of the One Health initiative, the medical profession does not seem to be fully aware of how veterinary science can contribute to human public health. It was postulated that transdisciplinarity could help fill knowledge gaps and that encouraging such transdisciplinarity should start with undergraduate students. Furthermore, intersectoral collaboration on zoonoses should not ignore the social sciences (e.g. assessment of indigenous knowledge and perception; participatory surveillance), which can contribute to a better understanding of the transmission of diseases and improve communities' participation in disease control activities.
