The Airborne Disease Debate
The discussion around the airborne transmission of diseases has evolved significantly, particularly highlighted during the COVID pandemic. Initially, many believed that diseases like cholera and typhoid were spread through contaminated air, a theory known as miasma. However, the germ theory of disease gained prominence around the turn of the 20th century, shifting focus away from air quality. This change delayed the recognition of airborne transmission pathways, leading to confusion about how COVID spread and illustrating the need for a broader understanding of the air we breathe.
