10 Deadly Diseases and Their Names: A Linguistic Autopsy

Language has a way of making even the most horrifying things sound poetic. History’s deadliest diseases aren’t just medical nightmares—they come with names that carry cultural, political, and linguistic weight. Some were named after symptoms, some after places (fairly or unfairly), and some were just terrifying enough to sound like medieval horror stories. So, let’s grab our linguistic scalpel and dissect the names of some of history’s most infamous diseases.

1. The Black Death – The Plague That Named Itself

The Black Death is the greatest PR campaign the bubonic plague never asked for. The name “Black Death” doesn’t actually come from medieval times but was first used in the 19th century. The Latin term atra mors can mean both "terrible death" and "black death," which might have led to the association. The disease itself, caused by Yersinia pestis, was marked by blackened skin due to necrosis, which certainly didn’t help its image. In reality, medieval people called it “The Great Mortality” or “The Pestilence.”

Linguistic takeaway? Naming a disease after color and destruction makes it sound like a heavy metal band. 🎸

2. The Spanish Flu – Blame the Messenger

The Spanish Flu (1918–1920) wasn’t actually Spanish. It was just reported more openly by Spain, which was neutral during World War I and didn’t have wartime censorship. Other countries had it too, but downplayed it to avoid lowering morale. Meanwhile, Spain was like, "Hey, people are dying en masse!"—and the world went, "So it's a Spanish thing?"

Linguistic takeaway? If you’re honest about a pandemic, history might just pin it on you. 📰

3. The Sweating Sickness – A Disease With a Weather Report

During the 15th and 16th centuries, England was hit by a mysterious disease known as “The Sweating Sickness.” That’s it. No fancy Latin, no obscure medical jargon. Just pure, sweaty, medieval horror. Victims would develop chills, body pain, and then, well, sweat profusely until they dropped dead. Doctors had no idea what caused it (and still don’t), but the name stuck.

Linguistic takeaway? Sometimes, simplicity is the scariest thing of all. 💦

4. The Ebola Virus – When Geography Backfires

Named after the Ebola River in the Democratic Republic of the Congo, the Ebola virus was first identified in 1976. Scientists needed a name, so they picked a nearby river. The unfortunate consequence? Ebola, a perfectly innocent geographical name, is now synonymous with one of the deadliest hemorrhagic fevers known to humanity.

Linguistic takeaway? If you ever discover a new disease, don’t name it after your hometown. Future tourism boards will hate you. 🌍

5. The Zika Virus – The Curse of Another Innocent Place

Like Ebola, the Zika virus was named after a location—the Zika Forest in Uganda—where the virus was first discovered in 1947. The virus itself was relatively obscure until the 2015 outbreak that linked it to birth defects. Much like Ebola, Zika turned a previously unknown location into a word of fear.

Linguistic takeaway? If you ever visit the Zika Forest, don’t expect relaxing jungle vibes. 🌳

6. COVID-19 – A Name Straight Out of a Sci-Fi Thriller

The name COVID-19 is a modern linguistic invention. It stands for COronaVIrus Disease 2019 (because it was discovered in 2019). Unlike historical diseases named after symptoms or locations, COVID-19 was deliberately given a neutral, scientific name to avoid stigma (because "Wuhan Virus" would have been politically charged and inaccurate).

Linguistic takeaway? Sometimes, avoiding controversy means choosing the dullest name possible. 🦠

7. The Great Pox (aka Syphilis) – The Ultimate Blame Game

Syphilis has had many names over the centuries, mostly depending on who people wanted to blame:

• The French Disease (according to the English and Italians)

• The Italian Disease (according to the French)

• The Spanish Disease (according to the Dutch)

• The Polish Disease (according to the Russians)

• The Christian Disease (according to the Ottomans)

Eventually, the name “Syphilis” stuck, thanks to a 16th-century poem by Girolamo Fracastoro about a shepherd named Syphilus who was cursed by the gods.

Linguistic takeaway? Naming a disease is a historical masterclass in passing the blame. 💩

8. Venereal Disease – The Blame Never Stops

The term “Venereal Disease” traces back to Venus, the Roman goddess of love and beauty. It was first used in the 16th century, not to honor her, but because the diseases were seen as being related to sexual activity. Over time, “venereal” became a more clinical term for diseases transmitted through sexual contact, often carrying the heavy stigma that comes with the association of sex and disease.

Linguistic takeaway? Even gods can’t save you from the blame game. 🏺

9. The Plague of Justinian – The Ancient Black Death

This disease, which struck during the reign of Byzantine Emperor Justinian in the 6th century, is often seen as an early iteration of the Black Death. It was caused by the same bacterium, Yersinia pestis, and decimated much of the population across the Mediterranean. The name, "Plague of Justinian," came from the emperor's association with the pandemic, and because it originated in his empire.

Linguistic takeaway? Even emperors can’t escape history’s grim sense of humor. 👑

10. Typhus – The Fever of the Ages

Typhus has been around for centuries, and the name comes from the Greek word typhos, meaning "stupor" or "delirium." The disease was historically spread by lice and fleas and was infamous for ravaging armies and populations in times of war, especially during sieges. Despite its long history, the name refers directly to the confused, stupor-like state victims often found themselves in.

Linguistic takeaway? Sometimes, the most vivid names come from the symptoms themselves. 🦠

The Power of Naming in Disease

What do all these names have in common? They tell stories. Disease names aren’t just labels—they reflect fear, stigma, geography, symptoms, and sometimes sheer randomness. In today’s world, health organizations are trying to move away from names that could create stigma (sorry, Spanish Flu and Ebola), but history has already left us with a rich linguistic autopsy of how we name what we fear.

So next time a new disease pops up, remember: what we call it will shape how we remember it.
