The World Health Organization (WHO)(link is external and opens in a new window)declares a pandemic when a disease’s growth is exponential. This means the growth rate skyrockets, and each day cases grow more than the day prior. In being declared a pandemic, the virus has nothing to do with virology, population immunity, or disease severity. It means...
A disease outbreak is endemic when it is consistently present but limited to a particular region. This makes the disease spread and rates predictable. Malaria, for example, is considered endemic in certain countries and regions.
The WHO defines pandemics, epidemics, and endemic diseases based on a disease's rate of spread. Thus, the difference between an epidemic and a pandemic isn't in the severity of the disease, but the degree to which it has spread. A pandemic cuts across international boundaries, as opposed to regional epidemics. This wide geographical reach is what m...
Several factors contribute to the outbreak of infectious diseases. Contraction can occur as a result of transmission from people, animals, or even the environment. For example: 1.

The COVID-19 pandemic (also known as the coronavirus pandemic ), caused by severe acute respiratory syndrome coronavirus 2 ( SARS-CoV-2 ), began with an outbreak in Wuhan, China, in December 2019. It spread to other areas of Asia, and then worldwide in early 2020.
An epidemic (from Greek ἐπί epi "upon or above" and δῆμος demos "people") is the rapid spread of disease to a large number of hosts in a given population within a short period of time. For example, in meningococcal infections, an attack rate in excess of 15 cases per 100,000 people for two consecutive weeks is considered an ...
Epidemic, an occurrence of disease that is temporarily of high prevalence. An epidemic occurring over a wide geographical area (e.g., worldwide) is called a pandemic. The rise and decline in epidemic prevalence of an infectious disease is a probability phenomenon dependent upon transfer of an.
