FOLLOW 1350: The Black Death
Responsible for the death of one-third of the world population, this second large outbreak of the bubonic plague possibly started in Asia and moved west in caravans.
Entering through Sicily in 1347 A.D. when plague sufferers arrived in the port of Messina, it spread throughout Europe rapidly. Dead bodies became so prevalent that many remained rotting on the ground and created a constant stench in cities.

FOLLOW The 10 deadliest epidemics throughout history
In an age of advanced medical technology and innovation, we can hardly imagine a time where the flu could be deadly. There are definitely still epidemics in our time, like for example the recent Ebola outbreak. However, the epidemics in the past involved far greater numbers of people.
The Third Cholera Pandemic (1852-1860)

Typhus fever in World War 1 (1945)

Typhus fever caused three million deaths in Russia alone.
FOLLOW A visual history of pandemics
As humans have spread across the world, so have infectious diseases. Even in this modern era, outbreaks are nearly constant, though not every outbreak reaches pandemic level as the COVID-19 has.
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. FOLLOW When Does an Epidemic Become a Pandemic?
Epidemic is a term that is often broadly used to describe any problem that has grown out of control. An epidemic is defined as "an outbreak of a disease that occurs over a wide geographic area and affects an exceptionally high proportion of the population." An epidemic is an event in which a disease is actively spreading.
Epidemic vs. pandemic An epidemic is a broad term used to describe any problem that is actively spreading and has grown out of control.
pandemic rel... 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.
