Why Is Chicken Pox Called Chicken Pox? Unveiled

Chickenpox, also known as varicella, is a highly contagious disease caused by the varicella-zoster virus. WHY.EDU.VN delves into the fascinating etymology behind its curious name, exploring various theories and shedding light on the most plausible explanations. Discover insights into the historical context, linguistic evolution, and medical understanding that shaped the naming of this common childhood ailment, providing comprehensive answers and addressing your curiosity about contagious diseases, viral infections, and childhood illnesses.

1. The Mildness Theory: A Common Explanation

The most widely accepted explanation for the name “chickenpox” is its perceived mildness compared to other, more severe diseases like smallpox and the great pox (syphilis).

Samuel Johnson’s Definition: In his 1755 dictionary, Samuel Johnson attributed the name to the disease being “of no very great danger.”
Oxford English Dictionary’s Perspective: The Oxford English Dictionary supports this theory, suggesting the name likely stems from the disease’s mild nature.

While simple, this explanation aligns with the historical context where diseases were often categorized based on their severity and impact on individuals. It reflects a time when medical terminology was less precise, and common names often arose from observations of the disease’s characteristics.

2. Thomas Fuller’s “Chicken Peck” Theory: A Whimsical Suggestion

In his 1730 Exanthemologia, Thomas Fuller proposed a more imaginative origin for the name, linking it to the appearance of the spots.

Specks Resembling Chicken Pecks: Fuller suggested that the small spots might have reminded people of “a Child had been picked with the Bills of Chickens.”

This theory, while intriguing, is largely considered a folk etymology, lacking strong historical or linguistic evidence. However, it provides a glimpse into the creative ways people attempted to understand and name diseases in the past.

3. Charles Fagge’s “Chick-Pease” Hypothesis: A Culinary Connection?

Charles Fagge, in his posthumously published The Principles and Practice of Medicine (1886), proposed a connection to “chick-pease” (chickpeas).

Chickpeas Resembling Vesicles: Lerman ( Clin Pediatr 1981;20:111-2) even demonstrated how soaked chickpeas placed on pink discs could resemble chickenpox vesicles.

However, this theory faces significant challenges:

Linguistic Origin of “Chick-pea”: The Oxford English Dictionary indicates that “chick-pea” originated from a scribal error for “cich-pease,” derived from the Latin Cicer arietinum.
Timing Discrepancy: This error occurred in the 18th century, after the term “chickenpox” was already in use.

4. The “Giccan” (To Itch) Theory: A Lingual Misinterpretation

Another suggestion links “chickenpox” to the Old English word “giccan,” meaning “to itch” (Lancet 1978;1:1152).

Connection to Itching: This theory suggests that the name could have arisen from the characteristic itching associated with chickenpox.

However, linguistic analysis casts doubt on this connection:

Pronunciation and Evolution of “Giccan”: The “g” in “giccan” represents the Old English letter yogh, pronounced like a “y.” This evolved into words like “yuke” (Scots) and “jucken/jeuken” (German/Dutch), all meaning “itch.”
Yogh’s Linguistic Path: Edmund Weiner at the Oxford English Dictionary confirmed that yogh never transformed into “ch.”
Timing Issue: “Giccan” evolved into “itch” in the 14th-15th centuries, predating the first recorded use of “chickenpox” in 1694.

5. The “Catchpenny” Theory: A Monetary Metaphor

The author proposes a folk etymology linking “chickenpox” to the historical value of coins.

Arabic Origin: Sikkah: The Arabic word “sikkah” (coin die) was used to name the mint in Venice, the “zecca.”
Zecchino to Chequeen: The “zecca” produced the “zecchino,” a coin known in English as a “chequeen.”
Chequeen’s Value: In Shakespeare’s time, a “chequeen” was a gold coin worth about eight old shillings (40p).
Evolution to Sequin and Chickeen: The “zecchino” evolved into “sequin” (a cheap decoration) through French. In India, it became “chickeen” or “chick,” a coin worth about four rupees.
Chicken Hazard and Chicken Nabob: “Chicken hazard” (a dice game for small stakes) and “chicken nabob” (a man returning from India with a moderate fortune) further illustrate the association of “chicken” with small value.

Therefore, the theory suggests:

Chickenpox as a “Catchpenny”: Compared to more serious diseases like smallpox and the great pox, chickenpox was merely a “catchpenny,” a minor ailment.

6. Historical Context of Chickenpox

To understand the etymology of “chickenpox,” it’s crucial to consider the historical context in which the disease was first identified and named.

Early Descriptions: While the varicella-zoster virus wasn’t identified until the 20th century, descriptions of chickenpox-like illnesses date back centuries.
Confusion with Smallpox: Chickenpox was often confused with mild cases of smallpox due to the similarity in rash appearance.
Differentiating Factors: Over time, medical observers noted that chickenpox was generally milder, less contagious, and resulted in lower mortality rates than smallpox.

This gradual differentiation likely contributed to the need for a distinct name to distinguish it from the more dreaded smallpox.

Scratching the blisters will cause scarring: While scratching can increase the risk of bacterial infection, the blisters themselves typically do not cause significant scarring.
Chickenpox is the same as shingles: Chickenpox and shingles are caused by the same virus (varicella-zoster virus), but they are distinct conditions. Shingles is a reactivation of the virus in individuals who have previously had chickenpox.

14. Chickenpox and Shingles: The Connection

Chickenpox and shingles are caused by the same virus, the varicella-zoster virus (VZV).

Initial Infection: Chickenpox: When a person is first infected with VZV, they develop chickenpox.
Latency: Virus Remains Dormant: After the chickenpox resolves, the virus remains dormant in nerve cells.
Reactivation: Shingles: Years or decades later, the virus can reactivate and cause shingles, a painful rash that typically occurs in a localized area.

Feature	Chickenpox (Varicella)	Shingles (Herpes Zoster)
Causative Agent	Varicella-Zoster Virus (VZV)	Varicella-Zoster Virus (VZV)
Population Affected	Individuals without immunity to VZV	Individuals with prior chickenpox infection
Rash Distribution	Generalized, itchy blisters	Localized, painful rash along a dermatome
Age Group	Primarily children	Primarily adults over 50
Contagiousness	Highly contagious	Less contagious (requires direct contact with blisters)
Prevention	Varicella vaccine	Shingles vaccine (Zostavax, Shingrix)

Understanding the connection between chickenpox and shingles is essential for preventing and managing these conditions.

15. Current Research on Chickenpox

Ongoing research continues to improve our understanding of chickenpox and its prevention and treatment.

Vaccine Development: Researchers are working on developing more effective and longer-lasting varicella vaccines.
