Worst Pandemics in History 🦠
Worst Pandemics in History 🦠 Global Pandemics All-Time List
How does the COVID-19 coronavirus pandemic compare with all the previous global pandemics? ADDucation’s list of the worst pandemics in history reveals the answers. From history we know epidemics and even the worst pandemics will eventually subside and life goes on but what can we learn from earlier global pandemics? With total daily births still more than double deaths we still have a population crisis to solve. In the meantime wash your hands regularly, maintain social distancing and wear masks or face coverings where appropriate.

- Notes: ADDucation’s list of pandemics in history in order is published for information only and is NOT medical nor lifestyle advice.
-  Deaths as a percentage of population is calculated by dividing the estimated world population at that time in history by the estimated number of deaths. This indicates the most deadly and worst pandemics in history.
-  Case Fatality Rate (CFR) is the proportion of people diagnosed with a disease who die, during the course of the disease, within a specified time. The CFR is also used to determine the Pandemic Severity Index (PSI) which ranges from category 1 to 5 for the biggest pandemics in history.
-  The COVID-19 CFR worldwide average. During an outbreak the CFR can fluctuate wildly and isn’t a good measure of the mortality risk as explained and discussed here.
Pandemic Severity Index:
The Pandemic Severity Index (PSI) was developed by the Centers for Disease Control and Prevention (CDC) to help report and plan for pandemics. The Covid-19 pandemic is a category 5 pandemic, and one of the worst pandemics in modern history, because the Case Fatality Rate (CFR) of the first wave peaked around 7.29% (worldwide average) and is currently between 2 and 3% during the second wave.
Shocking Worst Pandemics Facts
- Most of the measures taken to prevent the spread of the current COVID-19 outbreaks today are not new. The same measures were carried out during the 14th century Black Death pandemic in London and most of worst pandemics in history right back to Roman times!
- Although Covid-19 is the worst global pandemic there have been deadlier and longer lasting pandemics throughout history. For example the plague of Justinian from 541 AD killed over 12% of the population over two centuries, spanning eight generations.
