The Devastating Impact of Diseases 200 Years Ago: A Look Back at Medical History

The field of medicine has come a long way over the past two centuries with the discovery of vaccines, antibiotics, and other medical advancements that have helped mitigate the impact of diseases. However, it’s important to take a look back at the past to understand how far we’ve come. Two hundred years ago, the world was plagued by deadly diseases that wreaked havoc on populations all over the globe. This article delves into some of those diseases and how they impacted society.

The Outbreak of Cholera

One of the most devastating diseases that struck the world in the 19th century was cholera. This bacterial infection was caused by drinking contaminated water or eating contaminated food, and it caused severe diarrhea and vomiting that led to dehydration, electrolyte imbalances, and death. Between 1817 to 1824, cholera spread from India to Southeast Asia, the Middle East, and eventually Europe, where it caused several pandemics. In London alone, the disease claimed more than 20,000 lives in 1831-1832. Cholera was a scourge on society, and it wasn’t until the discovery of the Vibrio cholerae bacteria in 1854 that scientists could begin to understand how to prevent and treat it.

The Black Death

The Black Death, also known as the bubonic plague, is one of the deadliest pandemics in human history. It first emerged in China in the 1330s and spread via trade routes to Europe, where it caused widespread devastation between 1347 and 1351. The disease caused fever, chills, and muscle aches, followed by the development of painful, high-temperature lymph nodes or buboes. Approximately 25 million people are believed to have died during the Black Death pandemic, which represented a third of the European population. The disease continued to rear its head throughout history, with smaller outbreaks occurring until the 19th century.

The Spanish Flu

The Spanish Flu is another deadly disease that impacted the world in the 20th century. This viral infection caused fever, chills, and extreme fatigue. It is estimated that the Spanish Flu infected up to half a billion people, claiming the lives of between 50 million and 100 million people worldwide between 1918 and 1919. The Spanish Flu was particularly deadly because it targeted young, healthy people who had robust immune systems, killing them within days of infection.

The Impact of Historical Diseases on Society

The impact of these diseases on society goes beyond the staggering death tolls. Diseases like cholera and the Black Death accelerated social and economic changes, with labor shortages leading to wage increases and the development of new technologies. It’s also important to note that diseases have impacted cultural norms, with societal attitudes towards cleanliness and hygiene evolving as a result. The study of historical diseases has helped shape our understanding of medicine and has informed modern-day approaches to treatment and prevention.


The impact of diseases on human society has been devastating over the past two centuries. From cholera to the Spanish Flu, we’ve witnessed pandemics that have claimed millions of lives and shaped the course of history. By studying the impact of these diseases, we can better understand how far we’ve come in terms of medical advancements and how we can continue to innovate to create a healthier world.
