Understanding current practice of clinical medicine in the tropics (II). Bacterial and viral diseases. Malnutrition

In recent years, a significant number of physicians want to spend part of their medical training in health facilities in developing countries. In this setting, clinical skills are extremely important due to the limited available diagnostic resources. Bacterial diseases are common, but bacterial cultures are rarely accessible. In Africa, tuberculosis affects over 200 cases per 100,000 persons, and more than 22 million people live with HIV infection; both diseases are a serious public health problem. Malnutrition is endemic in many countries in Africa and is compounded by the continuous humanitarian and food crisis. In this paper, basic concepts of epidemiology, clinical features, diagnosis and treatment of major diseases that can be found in a rural health post in the tropics are discussed.
