This quarterly publication of The Royal Society of Medicine is a journal for those who serve the medical needs of populations in tropical and developing countries, with emphasis on district-level hospital and community services. It is a forum for the publication of original work arising from tropical experience; a vehicle for teaching the appropriate application of current knowledge to the special circumstances of remote communities; and a means of communication between medical staff dealing with the same disease problems in many different environments. Occasional supplements on topics of particular relevance to medical practice in developing countries are also published and are supplied free to subscribers.
