Up until a 1962 demonstration of tuberculosis airborne transmission, airborne transmission of all major respiratory diseases was assumed to be of insignificant or moderate consequence over the following fifty years.
Before COVID-19, only a small number of diseases—those that were blatantly spread to people not in the same room—were generally acknowledged as airborne. This is because the contact/droplet paradigm remained popular.
<h3>What does the term "airborne transmission" mean?</h3>
- The term "airborne transmission" refers to the propagation of droplet nuclei (aerosols) that retain their infectious properties after being suspended in air for a lengthy period of time and over great distances.
- Bacteria or viruses that cause airborne infections are most frequently spread by tiny respiratory droplets. When a person with the airborne sickness sneezes, coughs, laughs, or exhales in any other way, these droplets are released.
