Declaring a pandemic
When declaring a pandemic, the World Health Organization has the last word. There is no threshold, such as a certain number of deaths or infections, or a number of countries affected, that needs to be met.
And once a pandemic is declared, it becomes more likely that community spread will eventually happen, and governments and health systems need to ensure they are prepared for that.

When Does an Epidemic Become a Pandemic?
Epidemic vs. pandemic
An epidemic is a broad term used to describe any problem that is actively spreading and has grown out of control.

Disease Event Classification
Epidemiology is the branch of medicine that handles the following:
- Incidence: the occurrence of a disease over a specified period.
- Prevalence: how many people are affected within a population.
- Control of diseases: an appropriate public health response.
Two measurable factors mostly define the level of disease occurrence:
- The pattern and speed by which a disease moves.
- The size of the susceptible population.
The terms an epidemiologist use
- Sporadic refers to a disease that occurs infrequently or irregularly.
- Cluster refers to a disease that occurs in larger numbers even though the actual number or cause may be uncertain.
- Endemic refers to the constant presence and/or general prevalence of a disease in a geographic population.
- Hyperendemic refers to persistent, high levels of disease well above what is seen in other populations.
- Epidemic refers to a sudden increase in the number of cases of a disease above what is normally expected.
- Outbreak is the same as an epidemic but is often used to describe a more limited geographic event.
- Pandemic refers to an epidemic that has spread over several countries or continents, usually affecting a large number of people.

A visual history of pandemics
A History Of Pandemics
- A Pandemic is defined as the proliferation of a disease over the whole country or the entire world.
- Diseases and illnesses have troubled humanity since the earliest days, but ...
Quarantined
- The original use of the word Quarantine was the act of anchoring a ship arrived in Venice, Italy, for 40 days before landing.
- Infectiousness of any disease is measured by the reproduction number (R0, or R naught). For example, Smallpox has an R0 of 6 whereas Measles has an R0 of 16.
- Vaccination, if available, and herd immunity can curb the spread of disease.
- Big cities, with exploding population and traffic, can lead to the rapid spread of any infectious disease.

10 misconceptions about the 1918 flu, the 'greatest pandemic in history'
The influenza pandemic of 1918
It is often referred to incorrectly as the “Spanish flu.” Between 50 and 100 million people are thought to have died, representing as much as 5% of the world’s population. Half a billion people...
The origins of the "Spanish" flu
The so-called Spanish flu did not originate in Spain. The geographic origin of the flu is debated to this day, though hypotheses have suggested East Asia, Europe, and even Kansas.
The influenza pandemic from 1918 got this name most likely because of the WWI context: The major countries involved in the war were keen to avoid encouraging their enemies, so reports of the extent of the flu were suppressed in Germany, Austria, France, the United Kingdom and the U.S. By contrast, neutral Spain had no need to keep the flu under wraps. That created the false impression that Spain was bearing the brunt of the disease.
The end of mankind
The 1918 flu spread rapidly, killing 25 million people in just the first six months. This led some to fear the end of mankind and that the whole thing was caused by a form of super-virus.
Recent studies show that the high death rate can be attributed to crowding in military camps and urban environments, as well as poor nutrition and sanitation, which suffered during wartime.
