### 1) What “syphilis” is, and why its origin is controversial

Syphilis is a chronic infectious disease caused by the bacterium *Treponema pallidum* subsp. *pallidum*. Its “origin” is controversial because (a) the first clearly documented, explosive epidemic in Europe appears suddenly in the late 15th century, yet (b) *Treponema* diseases include closely related conditions (yaws, bejel) that can mimic some skeletal signs, making older cases hard to classify with confidence. ([jmvh.org][1])

### 2) The late-1400s European shock: the Naples outbreak (1494–1495)

Most historical reconstructions pivot on the first widely recorded European epidemic, commonly placed around 1494–1495 during the French campaign in Italy (often linked to the siege/occupation of Naples). Contemporary descriptions portray a frighteningly severe disease that spread rapidly across Europe in subsequent years, amplified by troop movements and dense urban networks. This “sudden-onset + fast diffusion” pattern is a key reason many scholars long favored the idea of a recent introduction or a sudden biological/social shift. ([jmvh.org][1])

### 3) How the disease got its name

The term “syphilis” was introduced in 1530 by the Italian physician-poet Girolamo Fracastoro in his work *Syphilis sive Morbus Gallicus* (“Syphilis or the French disease”). The naming history matters because early writers often used stigmatizing geographic labels (“French disease,” etc.), reflecting how societies framed blame during epidemics rather than clinical certainty about origins. ([PMC][2])

### 4) The three major origin hypotheses

Scholars typically group explanations into three frameworks:

**A. Columbian (New World) hypothesis**
Syphilis (in its venereal form) was brought from the Americas to Europe after Columbus-era voyages, then erupted in Europe by the mid-1490s. The strongest points historically were the timing (post-1492) and the abrupt European epidemic. Modern versions of this argument increasingly rely on ancient DNA and phylogenetics, not just chronicles. ([Nature][3])

**B. Pre-Columbian (Old World) hypothesis**
Syphilis (or a very similar treponemal disease) existed in Europe/Africa/Asia before 1492 but was misdiagnosed, confused with other diseases, or not recognized as distinct until social conditions changed. This view is supported by some claimed pre-1492 skeletal findings, but the central challenge is diagnostic specificity: bone lesions alone often cannot cleanly distinguish venereal syphilis from yaws/bejel or even from non-treponemal conditions without supportive context or molecular confirmation. ([PMC][4])

**C. Unitarian / evolutionary-ecological hypothesis**
All human treponemal diseases share a common ancestry; clinical “forms” (yaws vs bejel vs venereal syphilis) can shift with climate, hygiene, clothing, crowding, and sexual-network structure. In this framing, Europe’s late-1400s event could reflect a strain shift, a route-of-transmission shift, or a social tipping point rather than a single “importation moment.” (This is best seen as a synthesis model rather than a single, easily testable claim.) ([Wiley Online Library][5])

### 5) What counts as evidence (and why it’s hard)

Researchers triangulate multiple evidence streams:

* **Textual/chronicle evidence:** timing, symptoms described, geographic spread. Helpful for “when it became visible,” weaker for “where it began.” ([jmvh.org][1])
* **Paleopathology (bones/teeth):** can show patterns consistent with treponemal disease, but venereal syphilis is difficult to prove from skeletons alone, and misclassification risk is high. ([PMC][4])
* **Ancient DNA (aDNA):** potentially decisive when successful, but technically difficult (degradation, contamination control, sparse sampling).
* **Modern genomics/phylogeny:** compares lineages of *T. pallidum* subspecies; can suggest deep histories and divergence patterns, but conclusions depend on sampling and molecular-clock assumptions. ([PMC][6])

### 6) What recent ancient-genome work is changing

In the last few years, high-profile studies have reconstructed ancient *Treponema pallidum* genomes and used them to re-evaluate the “New World vs Old World” debate. For example, work published in *Nature* (2024) reported pre-Columbian treponemal genomes from the Americas and argued they help redefine treponemal history in ways consistent with a deep pre-1492 American presence of treponemal lineages. ([Nature][3])
A later *Nature* paper (2025) further illustrates how ancient genomes can reveal deep lineage history and complex evolutionary relationships among treponemal diseases—supporting the broader point that multiple treponemal lineages existed long before the first clearly recorded European epidemic, even if the precise pathway to Europe’s 1490s outbreak remains debated. ([Nature][7])

**Practical takeaway:** the “origin” question is no longer a simple binary. Evidence increasingly supports long-standing treponemal diversity and the plausibility that the dramatic European emergence involved both biology (which lineage, which transmission mode) and history (war, travel, urbanization, sexual networks). ([Nature][3])

### 7) Biological family tree: syphilis vs yaws vs bejel

All are caused by very closely related *T. pallidum* subspecies/strains. Venereal syphilis is typically sexually transmitted; yaws is usually spread by nonsexual skin-to-skin contact (often in children in endemic settings); bejel is also classically non-venereal. Their genetic similarity is one reason skeletal and historical retro-diagnosis is difficult—and why genomes (modern and ancient) matter so much to the origin debate. ([PMC][6])

### 8) A short “science-and-society” timeline (useful context, not just trivia)

* **1905:** *T. pallidum* identified microscopically (Schaudinn & Hoffmann). ([PubMed][8])
* **1910:** Salvarsan (arsphenamine) introduced as a landmark targeted therapy (Ehrlich/Hata era). ([PMC][9])
* **1943–1945:** penicillin validated and rapidly becomes transformative therapy for syphilis. ([JAMA Network][10])
  These milestones matter for “origin” discussions because they changed record quality (diagnosis) and disease course (treatment), which affects how we interpret modern vs historical severity.

### 9) Modern implications (public health “applications” of the origin story)

* **Mobility + conflict can reshape epidemics:** the 1490s European outbreak is a textbook example of how troop movements and mixing networks can accelerate spread. ([jmvh.org][1])
* **Stigma distorts reporting:** early naming practices (“French disease,” etc.) show how blame narratives can outrun evidence; this remains relevant in modern outbreak communication. ([PMC][2])
* **Diagnosis and treatment today are straightforward compared to history:** penicillin remains first-line across stages in major guidelines; screening and timely therapy prevent late complications and onward transmission. ([질병통제예방센터][11])

**Health note (general information):** If there is personal concern about exposure or symptoms, the appropriate step is clinical testing and professional treatment; self-diagnosis based on history is unreliable. Current treatment recommendations depend on stage and clinical findings. ([질병통제예방센터][11])

### 1) 매독이 무엇이며, 왜 “기원”이 논쟁적인가

매독은 *Treponema pallidum* (트레포네마 팔리둠)이라는 세균이 일으키는 만성 감염병입니다. 기원 논쟁이 큰 이유는 (1) 유럽에서의 “대유행”이 15세기 말에 갑자기 기록상 뚜렷해지고, (2) 매독과 매우 가까운 친척 질환(야스, 베젤 등)이 존재해 과거 유골·기록만으로는 “성병형 매독”을 확정하기가 어렵기 때문입니다. ([PMC][4])

### 2) 1494~1495년 나폴리(이탈리아) 유행이 핵심인 이유

대부분의 역사 서술은 1494~1495년 무렵 이탈리아 전역(특히 나폴리 전역/점령 시기)에서 프랑스군과 관련된 대규모 유행이 기록상 급부상했다는 점을 출발점으로 삼습니다. 당시 기록은 증상이 매우 격렬하고 전파가 빠르며, 이후 유럽 각지로 급속히 확산되는 양상을 묘사합니다. 이 “갑작스러운 등장 + 폭발적 확산”이 ‘신대륙 유입설’ 또는 ‘기존 질환의 변이·사회적 전환점’ 같은 설명을 촉발했습니다. ([jmvh.org][1])

### 3) ‘Syphilis(매독)’라는 명칭의 출현

‘syphilis’라는 용어는 1530년 프라카스토로(Fracastoro)가 쓴 *Syphilis sive Morbus Gallicus*에서 처음 정착한 것으로 널리 인용됩니다. 초창기에는 ‘프랑스병’ 같은 낙인성 호칭이 섞여 사용되었는데, 이는 원인 규명보다 사회적 비난이 앞서던 당시의 전형적 현상입니다. ([PMC][2])

### 4) 대표적 3가지 기원 가설

**A. 신대륙(콜럼버스) 가설**: 1492년 이후 신대륙에서 유럽으로 유입되어 1490년대 중반 유럽에서 폭발적 유행을 일으켰다는 설명입니다. 최근에는 고대 DNA와 계통학 증거가 논증의 핵심으로 이동하고 있습니다. ([Nature][3])
**B. 구대륙 선존재 가설**: 1492년 이전에도 유럽/아시아/아프리카에 존재했으나 오진·혼재되었고, 특정 시점에 질환 정체가 ‘매독’으로 분리되어 기록상 부각되었다는 견해입니다. 다만 유골 병변만으로는 야스/베젤과의 감별이 매우 어렵다는 한계가 반복적으로 지적됩니다. ([PMC][4])
**C. 통합(진화-생태) 가설**: 인간 트레포네마 질환군은 공통 조상에서 갈라졌고, 기후·위생·의복·도시화·성 네트워크 구조 변화에 따라 전파 양상(성접촉 중심 등)과 임상상이 이동할 수 있다는 관점입니다. ([Wiley Online Library][5])

### 5) 어떤 증거로 판단하며, 왜 결론이 어려운가

* **문헌 기록:** “언제/어디서 크게 보였는가”에는 강하지만, “최초 기원지” 확정에는 약합니다. ([jmvh.org][1])
* **유골(고병리학):** 트레포네마성 질환을 시사할 수 있으나, 매독을 단독 확진하기는 어렵습니다. ([PMC][4])
* **고대 DNA(aDNA):** 기술적으로 어렵지만 성공 시 결정적 근거가 될 수 있습니다.
* **현대 유전체/계통:** 분기 시점·전파 경로를 추정할 수 있으나 표본 편향과 분자시계 가정에 민감합니다. ([Nature][3])

### 6) 최근 고대 유전체 연구가 바꾸는 지형

*NATURE*(2024) 연구는 콜럼버스 이전 시기의 아메리카 지역 유골에서 트레포네마 고대 유전체를 제시하며, 트레포네마 질환군의 역사 재구성에 중요한 근거를 제공했습니다. ([Nature][3])
또 다른 *NATURE*(2025) 연구는 고대 유전체가 보여주는 깊은 계통 다양성과 복잡성을 강조하며, “1490년대 유럽 대유행”을 단일 사건으로 단순화하기 어렵다는 점을 뒷받침합니다. ([Nature][7])

### 7) 매독 vs 야스 vs 베젤: ‘가까워서 더 어려운’ 감별

이들 질환은 매우 가까운 *T. pallidum* 계열이 원인입니다. 전통적으로 매독은 성접촉 전파가 중심인 반면, 야스/베젤은 비성접촉(피부 접촉 등) 전파가 더 흔한 것으로 설명됩니다. 유전적 유사성이 크기 때문에 과거 기록·유골을 되짚을수록 혼재 가능성이 커지고, 그래서 유전체 증거의 비중이 커집니다. ([PMC][6])

### 8) “기원” 논쟁이 오늘에 주는 실용적 함의

* 전쟁·이동·도시 네트워크가 유행을 폭발시킬 수 있다는 점(1490년대 사례)은 현대 감염병에도 그대로 적용됩니다. ([jmvh.org][1])
* 낙인과 비난이 과학적 근거보다 앞서면 기록과 대응이 왜곡됩니다(초기 명칭의 역사). ([PMC][2])
* 현재는 진단·치료 표준이 확립되어 있으며, 주요 가이드라인에서 페니실린 계열이 핵심 치료로 제시됩니다. ([질병통제예방센터][11])

**건강 관련 일반 안내:** 개인적 증상/노출 우려가 있다면 자가판단보다 의료기관 검사를 통한 확인이 표준입니다. 치료는 병기와 임상 양상에 따라 달라집니다. ([질병통제예방센터][11])

## 日本語

### 1) 梅毒とは何か、なぜ「起源」が難しいのか

梅毒は *Treponema pallidum*（トレポネーマ・パリダム）による感染症です。起源論争が続く理由は、(1) ヨーロッパでの大流行が15世紀末に突然“歴史記録上”顕在化する一方で、(2) 近縁のトレポネーマ症（ヤaws、ベジェル等）が存在し、古い骨病変や文献だけでは性行為感染型の梅毒を確定しにくいからです。 ([PMC][4])

### 2) 1494〜1495年頃のナポリ流行の意味

多くの歴史研究は、1494〜1495年頃にイタリア（ナポリを中心）で大規模流行が記録され、兵の移動などを通じて急速に欧州へ拡大した点を重視します。この「急激な出現と爆発的拡散」が、外来導入説と社会・生物学的転換点説の双方を生みました。 ([jmvh.org][1])

### 3) 名称「Syphilis」の由来

「syphilis」という語は、1530年のフラカストロによる *Syphilis sive Morbus Gallicus* に由来するとされます。初期には地名を使った非難的呼称も多く、流行時のスティグマ形成を示す重要な社会史的材料です。 ([PMC][2])

### 4) 主要な3つの仮説

* **新大陸（コロンブス）仮説**：1492年以降にアメリカ大陸から欧州へ入り、1490年代に大流行した。近年は古代DNA・系統解析が論拠の中心。 ([Nature][3])
* **旧世界先在仮説**：1492年以前から旧世界に存在したが、誤診・混同され、ある時期に“梅毒”として顕在化。骨所見だけでは鑑別が難しい点が課題。 ([PMC][4])
* **統合（進化・生態）仮説**：トレポネーマ症群は近縁で、環境・衛生・都市化・性的ネットワークの変化で臨床像や感染経路が移行しうる。 ([PMC][6])

### 5) 近年研究の含意

*NATURE*(2024) などの古代ゲノム研究は、コロンブス以前のアメリカ大陸にトレポネーマ系統が深く存在した可能性を示し、議論を単純な二者択一から「多系統・長期史・複合要因」へ押し広げています。 ([Nature][3])

**健康に関する一般情報：** 心配がある場合、確定には検査が必要で、治療は病期で変わります。主要ガイドラインではペニシリンが中核です。 ([질병통제예방센터][11])

### 1) Qué es la sífilis y por qué su “origen” se discute

La sífilis es una infección causada por *Treponema pallidum* subsp. *pallidum*. Su origen es polémico porque el gran brote europeo aparece con claridad en los registros a fines del siglo XV, pero existen enfermedades treponémicas muy cercanas (yaws/pian, bejel) que pueden parecerse en hallazgos óseos y descripciones antiguas, dificultando una atribución retroactiva segura. ([PMC][4])

### 2) El hito europeo: 1494–1495 (Nápoles y la expansión)

Muchos autores señalan una gran epidemia documentada alrededor de 1494–1495 en Italia (asociada a la campaña francesa), seguida de una rápida propagación por Europa. El patrón de “aparición súbita + difusión acelerada” es central para las interpretaciones sobre introducción reciente, mutación o cambio social que favoreció la transmisión. ([jmvh.org][1])

### 3) Las tres hipótesis principales

* **Hipótesis colombina (Nuevo Mundo):** llegada desde América tras los viajes de finales del siglo XV; hoy se apoya cada vez más en ADN antiguo y filogenia. ([Nature][3])
* **Hipótesis precolombina (Viejo Mundo):** existencia previa en Eurasia/África, mal reconocida o confundida; el problema es la baja especificidad de los signos óseos sin confirmación molecular. ([PMC][4])
* **Hipótesis unitaria/eco-evolutiva:** las treponematosis forman un continuo; clima, urbanización, higiene y redes sexuales pueden cambiar la presentación y la vía de transmisión con el tiempo. ([PMC][6])

### 4) Qué está cambiando con los genomas antiguos

Estudios recientes en *Nature* (2024, 2025) muestran que los linajes treponémicos tienen una historia profunda y diversidad antigua, y aportan evidencia de presencia precolombina de linajes treponémicos en América. Esto hace más plausible que el evento europeo de los 1490s refleje una combinación de historia (movilidad, guerra, urbanización) y biología (linaje, modo de transmisión), más que una historia simple y lineal. ([Nature][3])

**Nota sanitaria (información general):** Las guías actuales mantienen la penicilina como tratamiento preferente; el esquema depende de la etapa clínica. La confirmación requiere pruebas diagnósticas. ([질병통제예방센터][11])

### 1) Ce qu’est la syphilis et pourquoi son origine est débattue

La syphilis est due à *Treponema pallidum* subsp. *pallidum*. Son “origine” reste débattue car l’épidémie européenne apparaît de manière spectaculaire dans les sources à la fin du XVe siècle, alors que des tréponématoses très proches (yaws/pian, bejel) compliquent l’interprétation des signes anciens, notamment sur les squelettes, sans preuve moléculaire. ([PMC][4])

### 2) Le tournant des années 1494–1495 (Italie / Naples)

De nombreuses synthèses historiques s’appuient sur une flambée majeure vers 1494–1495 en Italie, souvent associée aux campagnes militaires, suivie d’une diffusion rapide à l’échelle européenne. Cette dynamique “apparition brutale + propagation rapide” a alimenté l’idée d’une introduction récente ou d’un changement biologique/social favorisant la transmission. ([jmvh.org][1])

### 3) Les trois cadres explicatifs

* **Hypothèse colombienne (Nouveau Monde)** : arrivée depuis les Amériques après 1492; aujourd’hui renforcée par l’ADN ancien et la phylogénie. ([Nature][3])
* **Hypothèse précolombienne (Ancien Monde)** : présence antérieure mais mal reconnue; difficulté majeure de diagnostic rétrospectif sur la seule base des lésions osseuses. ([PMC][4])
* **Hypothèse unitaire/éco-évolutive** : continuum de tréponématoses, dont l’expression clinique et les voies de transmission peuvent évoluer avec l’environnement, l’urbanisation et les réseaux de contacts. ([PMC][6])

### 4) Apport des génomes anciens

Les travaux récents dans *Nature* (2024, 2025) soulignent une histoire profonde et une diversité ancienne des tréponèmes, avec des données précolombiennes provenant des Amériques. Ils rendent plus plausible une explication “multifactorielle” pour l’émergence européenne des années 1490 (contexte historique + dynamique biologique), plutôt qu’un récit unique et simplifié. ([Nature][3])

**Note de santé (information générale) :** Les recommandations actuelles retiennent la pénicilline comme traitement de référence; le protocole dépend du stade. Le diagnostic repose sur des tests. ([질병통제예방센터][11])
