Tropical diseases
Tropical diseases
Tropical diseases (pronunciation: /ˈtrɒpɪkəl diːˈziːz/) are diseases that are prevalent in or unique to tropical and subtropical regions. The diseases are less prevalent in temperate climates, due in part to the occurrence of a cold season, which controls the insect population by forcing hibernation.
Etymology
The term "tropical" refers to the geographical area in which these diseases are most prevalent, the tropics. The term "disease" comes from the Old French desaise, meaning lack of ease, discomfort, or distress.
