What if there are no antibiotics
The short version: without antibiotics, bubonic plague kills most of the people it infects, and the few who survive do so through luck and supportive care, not through any proven alternative treatment.
The historical record is brutal. In the Eyam plague of 1665-1666, 275 of 350 people died — a mortality rate of 79% [1]. That was before any antibiotic existed. In Madagascar from 1957 to 2001, the overall case fatality rate among 20,900 notified cases was 25.1%, and in the earliest period (1957-1961) it reached 55.7% [2]. The improvement over time likely reflects better supportive care and earlier detection, not a cure.
The retrieved studies on septic shock show what happens when the body cannot control the infection. In a cohort of 181 septic shock patients, 13.8% developed ischemic hepatitis (liver failure from low blood flow), and those patients had an 84% in-hospital death rate compared to 53% in those without it [5]. The odds of death more than tripled. Another study of 35 septic shock patients found that even with antithrombin III treatment, ICU mortality was 44% [4]. These are patients who got modern intensive care — fluids, vasopressors, ventilation. Without antibiotics to kill the bacteria, the infection keeps driving the sepsis.
The plague bacterium, Yersinia pestis, evolved its virulence over thousands of years. Bronze Age genomes show it existed 5,000 years ago [6]. The pla gene, which helps it spread from the buboes to the lungs, was already present in medieval strains [3]. This is a pathogen optimized to kill.
| Population | Cases | Deaths | Mortality rate |
|---|---|---|---|
| Eyam, 1665-1666 | 350 | 275 | 79% [1] |
| Madagascar, 1957-2001 | 20,900 | 5,246 | 25.1% [2] |
| Madagascar, 1957-1961 | - | - | 55.7% [2] |
| Madagascar, 1997-2001 | - | - | 20.9% [2] |
The evidence here does not test any specific non-antibiotic treatment against plague. What it shows is the natural history: a death rate between 25% and 79% depending on era and care quality. Supportive care — fluids, oxygen, management of complications — can reduce that toll but cannot eliminate the infection. The body's own immune system sometimes clears the bacteria, but it is a roll of the dice.
My call: without antibiotics, bubonic plague kills between 1 in 4 and 4 in 5 people, and no alternative treatment has been shown to change that. Confidence: high.

Incidence and outcome of ischemic hepatitis complicating septic shock
In a retrospective cohort of 181 septic shock ICU patients, ischemic hepatitis (aminotransferases equal to or higher than 1000 IU/L) occurred in 13.8% and was independently associated with increased in-hospital mortality (adjusted OR 3.47; 95% CI 1.02-11.8; P=0.047).
