The Black Death devastated medieval Europe as it spread rapidly via trade routes and ships.
Clinical Features
- The bubonic plague form had a 30-60% fatality rate untreated
- Pneumonic plague fatality approached 90-100% if untreated, spreading via respiratory droplets
- Septicemic plague killed within 24 hours with 100% fatality without antibiotics
- Incubation period for bubonic plague averaged 2-6 days
- Characteristic buboes were painful swellings in groin, neck, or armpits, 1-10 cm diameter
- Fever reached 38-41°C (100.4-105.8°F) with chills and extreme fatigue
- Delirium and mental confusion occurred in 50% of advanced cases
- Gangrenous lesions on fingers, toes, nose ("black death" moniker) due to disseminated intravascular coagulation
- Cough with bloody sputum hallmark of pneumonic plague
- Yersinia pestis bacterium multiplies in flea gut, forming biofilm blocking proventriculus
- Human infection via flea bite introduces 10-100 bacilli, multiplying rapidly in lymph nodes
- Untreated bubonic plague mortality peaked at days 3-5 post-symptom onset
- Autopsy findings showed massive lymphadenopathy and splenic enlargement
- Contemporary accounts described victims turning "black" from internal hemorrhaging
- Plague bacilli survived in rodent populations for years between outbreaks
- Streptomycin treatment reduces bubonic mortality to 10%
- Diagnosis via PCR on bubo aspirate or blood detects Y. pestis DNA
- Coma and shock preceded death in 80% of septicemic cases
- Vomiting of blood (hematemesis) reported in 20-30% of pneumonic victims
- Flea vector Xenopsylla cheopis prefers rats, transmitting at 1-10% efficiency per bite
- Lymphadenitis caused buboes suppurating foul pus after 10-14 days in survivors
- Tachycardia and hypotension developed in advanced plague sepsis
- Post-plague survivors gained temporary immunity lasting 1-3 years
- Medieval physicians noted 1-3 day prodrome of malaise before buboes
- Plague meningitis rare but with 70% fatality, CSF pleocytosis
Clinical Features Interpretation
In light of these chilling statistics—where one could either endure a grotesque lottery with buboes, face near-certain suffocation from a cough, or be guaranteed a swift, blackening end within a day—it is clear the Black Death operated with a grim, hierarchical efficiency, offering its victims only a menu of increasingly horrific and probable fatalities.

Cultural and Historical Legacy Interpretation
The Black Death didn't just kill people; it meticulously rearranged the entire cultural furniture of Europe, leaving behind a world where more people were praying in private chapels, laughing at satirical stories, building simpler churches, and questioning authority, all while trying to forget the sight of mass graves.
