Hey YouTube, Jim here!
Welcome to Top10Archive!
With the times we’re living in right now, it’s no surprise we’re looking for ways
to figure out whether pandemics like this have happened before, how we’re going to
get through it, and just generally trying to think about how this is the new normal.
It's crucial to keep in mind that after many, many pandemics, humanity has continued to
step forward.
But it makes you wonder, what's the worst pandemic that humans have went through, and
how close have we came to extinction because of them?
Here is the list of the Top 10 Deadliest Pandemics In History!
It should also be noted that we organized our list by the percentage of the human race
these pandemics killed at the time, not by body count.

Plague of Athens - 100,000 (0.1%) Throwing it way back to 430 B.C. we’re in
the aftermath of the war between Athens and Sparta, the countries were just getting back
to their normal life when they were hit with a 5-year plague.
The world population of these times was estimated to be about 100 million people, so, given
that about 100,000 people died from the Plague of Athens, this was a pretty big death toll
by killing roughly 0.1% of the entire world.
The symptoms included, according to a particularly decorative writer and historian, Thucydides,
“violent heats in the head, and redness and inflammation in the eyes, the inward parts,
such as the throat or tongue, becoming bloody and emitting an unnatural and fetid breath.”
9.
Plague of Cyprian 1 Million (0.53%) The Plague of Cyprian was a pandemic that
afflicted the Roman Empire from 249 to about 262 AD.
During the height of the outbreak, an estimated 5,000 people were dying each day.
The exact number is still unknown, but sources say "at least" 1 million people lost their
lives.
The agent of the plague is also still unknown because of sparse sourcing, but most historians
believe it to be either from smallpox, pandemic influenza, or viral hemorrhagic fever.
Although Rome would later fall about 200 years later in 476 AD, this plague nearly did them
in, during what is known as the "Crisis of the Third Century", when the Roman Empire
nearly collapsed from barbarian invasions, migrations, civil wars, peasant rebellions,
political instability, economic depression, and debasement of currency.
In the end, of the 190 million people alive at the time, 1 million lost their lives to
the plague, giving it a total death rate of 0.53% of the world population, or 1 out of
every 190 people.
8.
The HIV/AIDS Pandemic - 36 Million (0.6%) First identified in the Democratic Republic
of the Congo in 1976, HIV/AIDS has been an ongoing pandemic ever since, killing more
than 36 million people since 1981 - between 1 and 2 million people annually.
Currently, there are between 31 and 35 million people living with HIV, the vast majority
of those are 21 million people living in Sub-Saharan Africa, where 5% of the population is infected.
Although HIV/AIDS is a slow killer, it's still pretty much a guaranteed death sentence to
those who have it, especially to those who go untreated.
Thanks to modern medicine, many people go on to live rather productive lives, but there
is still no known cure - at least, released to the public.
Since the world population has changed from 4.1 billion to 7.8 billion people since 1976,
it's hard to measure what percentage of the world this pandemic has killed, but if we
take the median number of 5.95 billion, then 36 million people equates to about 0.6% of
the entire world, or about 1 out of every 160 people.
7.
Third Plague Pandemic - 12 Million (1%) In 1855, a third, and for now, final bubonic
plague pandemic that began in Yunnan, China, which spread to all inhabited continents.
It was the weakest outbreak of the three, but it still killed more than 12 million people,
10 million of which were in India alone.
The pandemic remained active until 1960, when worldwide casualties dropped to less than
200 per year, but the vast majority of the deaths were within a few years of the first
reported case.
Given the population of 1.2 billion in the 1850's and killing 12 million people, this
outbreak killed an estimated 1% of the entire world, or 1 out of every 100 people.
6.
The Spanish Flu Pandemic of 1918 - 50 million (2.77%)
The 1918 influenza pandemic was the most severe pandemic in recent history.
It was caused by an H1N1 virus with genes of avian origin.
It spread worldwide during 1918-1919, and there is not a universal consensus regarding
where the virus originated.
In the United States, it was first identified in military personnel in spring 1918.
It is estimated that about 500 million people or one-third of the world’s population became
infected with this virus, and had a death-rate of about 10%.
The world population was roughly 1.8 billion people in 1918, while an estimated 50 million
people died, meaning the pandemic killed 2.77% of the entire world population, or about 3
out of every 100 people.
5.
Antonine Plague - 5 Million (2-3%) Another soldier-induced plague.
Is this a sign?
Should we stop getting into wars and prevent back-to-back high death tolls?
In this case, the Roman Empire, circa 165 and 180 A.D, was campaigning and came back
with the disease.
Some think the soldiers brought it home after a war with Parthia.
The plague ended the long Roman Peace period during which Rome was at its peak.
After the disaster, people turned to Christianity for solace and it became increasingly popular
among the Roman people.
Given that there were about 180 million people alive in this time period, 5 million people
would account for about 2.78% of the entire world population, or about 3 out of every
100 people.
4.
Cocoliztli Epidemic - 15 Million (3.2%) Between the years 1545 and 1548 A.D, this
infection caused the cocoliztli epidemic, a form of viral hemorrhagic fever that killed
15 million inhabitants of Mexico and Central America.
The population was already weakened by extreme drought, so the disease proved to be utterly
catastrophic.
"Cocoliztli" is the Aztec word for "pest."
A recent study examined DNA from the skeletons of victims and found that they were infected
with a subspecies of Salmonella known as S. paratyphi C, which causes enteric fever, a
category of fever that includes typhoid.
15 million people ultimately died during a time where the world population was roughly
460 million people, giving a worldwide death toll of about 3.2%, or again, about 3 out
of every 100 people.
3.
The Justinian Plague - 19-50 Million (10-25%) This plague marked the end of the Byzantine
Empire.
This was another case during which about 10%-25% of the world population died, in just 1 year
in fact, between 541 and 542 AD.
The actual death count is still uncertain, but estimates compared to the world population
at the time sets the number between 19 and 50 million people.
The plague was named after Emperor Justinian who reigned from A.D. 527 to 565 with lots
of success, spreading to the Middle East and Western Europe from the Mediterranean.
Even Justinian himself contracted the plague, but survived.
However, it was the perfect time for others to take their territory back and take advantage
of the empire’s weakness, which they certainly did.
Researches speculate the plague was caused by the bacterium Yersinia pestis, which often
lead to necrosis in its victims.
2.
Smallpox - 500 Million (17.9%) When we think of a pandemic, we think of a
virus or disease that comes and goes rather quickly - but smallpox coexisted with humans
for a very long time.
Its biggest outbreak, though, lasted for roughly 100 years, between the years of 1877 to 1977,
when it was eradicated, but not before killing more than 500 million people.
Smallpox seemed to be a disease that wouldn’t quit.
It rode along on explorations, boat rides, and it killed 30% of the people it infected.
If you didn’t die, you were left with scars to prove that you’d had it.
The European spread, though, is nothing compared to the impact it had in the Americas when
the first European explorers made their way over.
Indigenous people in Mexico and The US had never experienced something like this and
without herd immunity built up, the virus ravaged their population, slicing their numbers
by 90-95% in 100 years.
Like HIV/AIDS, it's hard to measure what percentage of the world this pandemic has killed, but
if we take the world population of 1.4 billion in 1877 and 4.2 billion in 1977, and get the
median number of 2.8 billion, then 500 million people equates to about 17.9% of the entire
world, or about 1 out of every 5 people.
1.
The Original Black Death - 125 Million (26.3%) The Black Death, also known as the Pestilence
and the Plague, was the most fatal pandemic recorded in human history, resulting in the
deaths of up to 75–200 million people in Eurasia and North Africa, peaking in Europe
between the years of 1347 to 1351.
The plague is caused by the bacterium yersinia pestis, which can cause septicaemic and pneumonic
plagues, but most commonly results in bubonic plague.
This was the 2nd plague pandemic recorded, after the Plague of Justinian.
It was easily spread not by rodents, but by fleas on those rodents.
It's estimated that the plague killed between 30-60% of Europe's population, and brought
the world population down from 475 million to 350 million people.
Meaning, it killed an estimated 26.3% of the entire world population, or 1 out of every
4 people.
