Cambodia Baseline Surveys and Assessments for Monitoring and Evaluation

National HIV/AIDS programmes world wide comprise a variety of interventions or actions aimed at reducing spread of HIV, providing care & support to the affected and alleviating socio-economic and human impact. Resources are always limited, and being able to decide which interventions are most appropriate and cost-effective (and thus to be given highest priority) is of critical importance. Different types of trials or operational research have been used to demonstrate effects of a given intervention conducted in a particular setting (efficacy).
