This article describes the development of a health research strategy f
or the control of diseases associated with poverty, tropical diseases
(infectious as well as noncommunicable), diseases associated with affl
uence, the treatment and care of the sick, and the delivery of health
services. Since socioeconomic, technological and behavioural changes d
etermine the process of health development, the severe constraints in
financial, material and human resources must be addressed by promoting
better methods of policy analysis, planning and research. Countries w

services in nutrition, immunization and sanitation.
