The Difference between Pandemic and Epidemic is given here. An epidemic is a disease or virus that spreads through a country or region, affecting large numbers of people. Instead, a pandemic is the spread of the infectious agent in different countries or nations that may or may not cause high mortality.
An epidemic is a disease that spreads for a time through a country, affecting a large number of people.
An infection is considered an epidemic when it exceeds the estimated number of cases in a given period of time.
An endemic can become an epidemic if it exceeds the expected cases, this means that if a disease is considered eradicated (endemic 0) and then a case occurs, it already becomes an epidemic.
The term pandemic comes from the Greek pandêmon nosêma, which means a disease that affects the entire town.
Before 2009, the WHO considered a pandemic as a simultaneous infection by infectious agents in different countries with significant mortality in relation to the proportion of the population that has been infected.
The current concept eliminates the “mortality” characteristic as many pandemic diseases are not necessarily fatal.
According to the WHO for a pandemic to occur it is necessary for a new virus to appear, therefore the population is not immune to it.
- The virus can cause serious cases.
- The virus has the ability to be transmitted from person to person effectively.

Difference between Pandemic and Epidemic
- A pandemic is the worldwide spread of a new disease according to the World Health Organization (WHO). This is because it is a new virus against which no one has defenses to control it and can be transmitted from person to person effectively.
- An epidemic is a disease that spreads across a country, affecting large numbers of people. It corresponds to the growth of an endemic disease or the appearance of patients where the infection was considered absent.
