Did everyone die that had the bubonic plague before antibiotics?

No, not everyone who had the bubonic plague before antibiotics died. While the bubonic plague is a highly infectious and deadly disease, there were some people who were able to survive it. In fact, some studies suggest that as much as 30% of people who contracted the bubonic plague may have survived.

There are a number of factors that could have contributed to a person's survival of the bubonic plague. These include:

* The person's immune system: Some people may have had a stronger immune system that was able to fight off the infection.

* The severity of the infection: The severity of the infection could vary from person to person. Some people may have had a milder case of the disease that was more likely to be survived.

* The availability of medical care: While antibiotics were not available, there were some other treatments that could help to improve a person's chances of survival. These treatments included bloodletting, herbal remedies, and quarantine.

It is important to note that even though some people were able to survive the bubonic plague, it was still a very deadly disease. The mortality rate for the bubonic plague is estimated to have been between 30% and 60%.
