Globalization of infectious diseases.

Globalization, the flow of information, goods, capital and people across political and geographic boundaries, has helped to spread some of the deadliest infectious diseases known to humans. The spread of diseases across wide geographic scales has increased through history. Etiology, the modern branch of science that deals with the causes of infectious disease, recognizes five major modes of disease transmission: airborne, waterborne, blood borne, by direct contact, and through vector (insects or other creatures that carry germs from one species to another). The diseases that most affect our world are: Plague, Measles, Typhus, Syphilis, Smallpox, Leprosy, Malaria, Tuberculosis and HIV/AIDS. This phenomenon can affect our way of life and has a lot of consequences in many countries. It is important to be careful and implement prevention measures.
