Burden of diseases in poor resource countries: meeting the challenges of combating HIV/AIDS, tuberculosis and malaria

Abstract

Poverty, ill health and ignorance are closely interlinked and each is a determinant of the other. HIV/AIDS, malaria and tuberculosis are by far the commonest causes of ill-health and death in the poorest countries of the world which happen to be in the tropics and temperate countries in Africa, Asia and South America. Morbidity and mortality from these three diseases have a major socio-economic impact on individuals, communities and nations, due to the vicious cycle of poverty, ill health and ignorance. In Tanzania morbidity due to HIV/AIDS, tuberculosis and malaria leads to irrecoverable losses in productivity, inadequately trained workforce due to absence from training by the sick, heavy health care budgets to treat these otherwise preventable diseases, less competitive economy, higher labour force turnovers and unstable national budgets. If not controlled continuing rise in incidence of HIV/AIDS, malaria and TB may threaten the survival of small enterprises and ability to attract foreign investments leading to a rise in unemployment. Thus, investments in the improvement of health including HIV/AIDS, malaria and TB if done well will bring substantial benefits for the national economy including an increase in productivity. In this paper a review of the impact of HIV/AIDS, TB and malaria in Tanzania is done with an attempt to propose how research can contribute to improved efforts towards more effective prevention and control efforts. The need for multidisplinary research efforts in addressing the three disease conditions is proposed.
