Quarantine: The Ancient Health Protocol (Discovered 1847)
Dr. Ignaz Semmelweis shocked medicine in 1847 by proving that isolating sick patients and implementing hand washing slashed mortality rates from 10% to 1%. Louis Pasteur’s later work on germ theory in 1861 explained why isolation prevents disease spread. Leviticus 13:46 had instructed infected people to “dwell alone” and be declared unclean thousands of years before science understood bacterial transmission through human contact.
