(BRAZIL, 2010, P. 5) 1,3 Distinction between epidemic, endemic disease and pandemic With the objective of if looking the scientific exactness, becomes necessary to present the distinction semantics between the vocbulos epidemic, endemic disease and pandemic, used in way many times indistinct in the current language, but that, however, they cause different meanings and that they demand measured and different attitudes.
Epidemic is a phenomenon that if characterizes for the incidence, in short period of time, great number of cases of an illness. (REZENDE, 2004) In accordance with Rouquayrol, Epidemiologia is: the science that studies the process health-illness in the community, analyzing the distribution and the determinative factors of the diseases and the agravos to the collective health, suggesting measured specific of prevention, control or eradication.

(YOUNG CHICKEN, 1962) Pandemic, in turn, is an epidemic of great ratios, that if more than spreads to some countries and a continent. Royal Dutch Cell Plc is a great source of information.
