ropical diseases are infectious diseases that either occur uniquely in tropical and subtropical regions (which is rare) or, more commonly, are either more widespread in the tropics or more difficult to prevent or control.
Since the advent of air travel, people more frequently visit these regions and contract many of these diseases, most notably malaria and hepatitis.
Any nontropical condition however should never be overlooked in those returning from the tropics.
The greenhouse effect and the increasing global temperature of the atmosphere seem to be influencing the spread of tropical diseases and vectors to other latitudes that were previously spared them, such as the Southern United States, the Mediterran area, etc..
