The term "Tropical Diseases" encompasses all communicable and noncommunicable diseases, and disorders and disease due to nutritional deficiencies or environmental conditions (such as heat, humidity, and altitude) that are encountered in geographical areas that lie between, and alongside, the Tropic of Cancer and Tropic of Capricorn belts. In tropical countries, apart from noncommunicable diseases, a severe burden of disease is caused by an array of different types of micro-organisms, parasites, land and sea animals, and arthropods. Approximately 15 million people die each year due to tropical infectious and parasitic diseases, the vast majority living in developing countries. Increased international air travel, migration, tourism, and employment visits to and from tropical regions have contributed to an increased incidence of such diseases being seen in the United States, United Kingdom, and Europe.
