Deep dives
The Long Road to Understanding Airborne Disease
The concept of diseases being transmitted through the air was not widely accepted until relatively recently in scientific history, primarily due to the complexity and fear associated with the notion. Initially, many believed that illness arose from 'bad air' or miasmas, disregarding the idea that living microorganisms could cause disease. This belief proved to be a significant blind spot, as visible microorganisms were often dismissed despite the advent of the microscope in the late 16th century. Over time, as scientific evidence mounted in favor of germ theory, the understanding of airborne diseases began to shift, although a lag still existed within public health perspectives.
