Alongside good general medical abilities, tropical medicine knowledge and skills are an asset in many MSF projects. The exact extent however, will depend on your specific mission. Some missions focus on one disease, such as a sleeping sickness or tuberculosis program, where you will become very familiar with that particular disease. Of course you will not be treating this disease exclusively, so the more you know about what is endemic to that region, the better. At the project location in the field, MSF often has a medical library where you can access standard reference books, such as Harrison's Principles of Internal Medicine, the Merck Manual, Nelson's Pediatrics, and Manson's Tropical Medicine. MSF also has its own publications which are practical and to-the-point. These resources can help you with specific situations such as dealing with a measles or meningitis epidemic. MSF also has a comprehensive “treasury”, a set of electronic documents with extensive medical and nonmedical information that can often help field teams in remote settings make key clinical and operational decisions.
