The WHO Has a New Definition of Airborne Disease Transmission

During the initial chaos of the COVID-19 pandemic, shortages of cleaning supplies were rampant, driven by a focus on surface sanitation rather than airborne transmission. Despite mounting evidence, the World Health Organization (WHO) maintained that the virus wasn't airborne until late 2021. This discrepancy led to confusion and debates among scientists and physicians.

Finally, in November 2021, the WHO revised its guidelines, introducing new definitions distinguishing between direct contact and airborne transmission. This update, which doesn't rely on droplet size or distance, could significantly impact infection control standards globally.
