Major Pandemics in History
12 major disease pandemics from the Antonine Plague of 165 CE to COVID-19, ranked by estimated death toll. Tuberculosis alone cumulatively killed over a billion people; smallpox was the only one ever eradicated.
By estimated death toll
| # | Pandemic | Pathogen | Period | Deaths |
|---|---|---|---|---|
| 01 | Tuberculosis Consumption | Mycobacterium tuberculosis | 9000 BCE–present | 1–1.5 billion cumulatively over the past 200 years; ~1.25 million annually today |
| 02 | Smallpox Variola | Variola virus (major and minor strains) | 10000 BCE–1980 | 300–500 million in the 20th century alone; perhaps 1 billion+ cumulatively |
| 03 | Black Death Great Mortality | Yersinia pestis | 1347–1351 | 75–200 million |
| 04 | 1918 Influenza Pandemic Spanish Flu | Influenza A virus, H1N1 subtype | 1918–1920 | 50–100 million |
| 05 | Plague of Justinian First Plague Pandemic | Yersinia pestis | 541–549 | 15–100 million |
| 06 | Cholera pandemics Asiatic cholera | Vibrio cholerae | 1817–present | ~50 million cumulatively across seven pandemics; ~100,000 annually today |
| 07 | HIV/AIDS Acquired Immunodeficiency Syndrome | Human Immunodeficiency Virus (HIV-1 and HIV-2) | 1981–present | ~42 million cumulatively since 1981; ~600,000 annually |
| 08 | COVID-19 SARS-CoV-2 Pandemic | SARS-CoV-2 | 2019–present | ~7.1 million reported; ~20–28 million estimated excess deaths |
| 09 | Antonine Plague Plague of Galen | Probably smallpox (Variola virus) | 165–180 | 5–10 million |
| 10 | Asian Flu 1957 Pandemic | Influenza A virus, H2N2 subtype | 1957–1958 | 1–4 million globally |
| 11 | Hong Kong Flu 1968 Pandemic | Influenza A virus, H3N2 subtype | 1968–1970 | 1–4 million globally |
| 12 | 2009 H1N1 Swine Flu Pandemic Swine Flu | Influenza A virus, H1N1pdm09 subtype | 2009–2010 | 151,700–575,400 globally |
Death tolls reflect mainstream scholarly estimates; ranges are wide for pre-modern events. The bar visualises the upper-bound estimate. Tuberculosis's unique cumulative toll reflects two centuries of endemic mortality rather than a single outbreak.
