The process of rapidly spreading infectious diseases within a short period of time into a large number of people in a given population and spread over to several countries or continents, is known as Epidemic. From a Greek word an epidemic is derived, which refers to upon or above people. bubonic plague, cholera, influenza, Smallpox are some of the common examples of Epidemics.

The worldwide spreading of a new disease is known as pandemic. A larger version of an epidemic, a pandemic. In other words, it is known as a pandemic, when an epidemic goes out of control. It is likely to be a pandemic, if an epidemic covers many countries spreading through continents. There are different types of pandemics. One of the best examples for the most destructive global pandemics in history is  HIV or AIDS. The pathogenic or harmful microorganisms, such as bacteria, viruses and other parasites that can spread, directly or indirectly, from one person to another through the air, water, and other modes of transmissions, these are the main cause of epidemic and pandemic. Humans do begin to develop some immunity after a pandemic emerges, and spreads, but this takes time. The virus subtype can then circulate among humans for several years, leading to occasional epidemics.

The COVID-19 outbreak has been declared as a pandemic officially by the WHO on march 11 due to the global spread and severity of the disease.

When a new virus strain or subtype becomes easily transmittable between humans, or by bacteria that become resistant to treatment with antibiotics, then a pandemic is caused. Sometimes, pandemics are caused simply by a new ability for the disease to spread rapidly, this was the case with the Black Death in the 14th century. Humans may have little or no immunity to a new virus. A new virus does not have to be able to spread from person to person, but if it changes or mutates, it can easily begin to spread. In this case, a pandemic may occur. In the case of the flu, seasonal outbreaks (or epidemics) are usually caused by subtypes of a virus that is already circulating among a population.

An outbreak of disease that affects many in a population and begins to spread rapidly is known as an epidemic.

A larger epidemic is pandemic, a pandemic covers several countries or spreads from one continent to another.

If it affects a certain number of people within a short period of time, typically within 2 weeks, that outbreak of disease is considered as an epidemic.

The number of people affected or killed doesn’t matter as much as the rate of spread and how far it has spread in pandemic outbreaks.

Epidemic is something that belongs to a particular person or country.
