Deadliest Pandemics in History: A Historical Overview

Here’s a breakdown of the pandemics discussed in the provided text, along wiht key details from Our World in Data as presented in the article:

Pandemics Before the 19th Century:

* The Black Death (1347-1353):

* Caused the death of 50-60% of the European population (approximately 50 million people in six years).
* Outbreaks also occurred in Western Asia, the Middle East, and North Africa.
* Recurrent outbreaks continued until around 1690 (known as the second plague pandemic).
* Columbian Exchange (1492-1600):

* indigenous population of America before 1492: approximately 54 million.
* Deaths during this period: nearly 48 million (a 90% reduction).
* Caused by diseases introduced from Europe (smallpox, cholera, measles, diphtheria, influenza, typhoid fever, bubonic plague) along with conquest, slavery, and war.

Pandemics Since the 19th Century:

* Cholera (Since 1817):

* Seven cholera pandemics have been recorded.
* At least 23 million deaths in India alone (between 1865 and 1947).
* Originated in the Indian subcontinent and spread through trade, travel, and conflict.
* Influenza:

* first certain influenza pandemic: 1580.
* between 10 and 26 influenza pandemics have been recorded since then.
* Spanish Flu (1918-1920): 50-100 million deaths.
* Russian Flu (1889): Around 4 million deaths.
* Asian Flu (1957): Nearly 2 million deaths.
* Hong Kong Flu (1968): Nearly 2 million deaths.
* Swine Flu (2009): Estimates range from 100,000+ deaths.

Key takeaway: Our World in Data uses a timeline visualization where circle size represents the number of deaths, and pandemics without quantifiable data are represented without an estimate.
