Tropical Infectious Diseases

Tropical diseases are the one which are prevalent in or unique to tropical and subtropical regions. Disease spread is very less in temperate climates, due in part to the occurrence of a cold season, which controls the insect population by forcing hibernation. The most common disease carrier or vectors are the insects such as mosquitoes and flies. These insects may carry a bacterium or virus, parasite that is infectious to humans and animals. Insect “bite” is the major cause for the transmission of most of the disease which also causes transmission of the infectious agent through subcutaneous blood exchange. For most of the diseases, vaccines are not yet available. 

 Examples of Tropical Infectious Diseases:

1.  Cholera
2.  Escherichia coli tuberculosis and Hansen's disease (leprosy).
3.  Parasitic single-celled protozoa
