The Historical Oversight of Airborne Pathogens
Research from the 1930s revealed that airborne droplets containing pathogens like influenza and tuberculosis could remain suspended in the air for extended periods. Despite this significant finding, the knowledge was largely forgotten and disregarded, leading to misconceptions during the COVID-19 pandemic about how the virus spreads. As a result, COVID was initially treated as if it could not be airborne, which contributed to widespread transmission. This illustrates a grave lapse in public health communication and understanding, where lessons from the past were overlooked at a critical time.
