This is a superb CD Rom covering various aspects of HIV and AIDS by means of interactive tutorials. It is clear, concise, and up to date and has tutorials under the following headings: Overview, Biology of HIV, Natural history, Infections and malignancies, Epidemiology, Transmission and risk factors, Prevention, Diagnosis and monitoring, Women and children, Management, Social and psychological issues.

Each tutorial is self contained (which does lead to some duplication) and has self assessment questions—usually with click and drag matching of statements or true/false boxes. The information itself is well illustrated and contains animations and a video clip, together with further information/annotations in pop up boxes. At the end of each section there is a set of summary points, a reading list, and further activities such as internet sites.

There is a searchable picture index which allows you to search, view, and save sets of images for reference and lectures (although copyright does apply), and a glossary of terms.

Overall this is an excellent CD Rom providing good information, presented in an attractive and usable way, with a wealth of illustrations. I would strongly recommend it.
