This marks the primary time such an settlement has been reached, and it goals to forestall the confusion that occurred in the course of the early phases of the COVID-19 pandemic, which some scientists imagine led to pointless lack of life, based on a Reuters report.
On Thursday, the WHO launched a technical doc outlining the brand new definition, which is taken into account the preliminary step in direction of bettering prevention measures for airborne transmission of present ailments like measles and potential future pandemic threats. The doc states that the time period “by the air” can be utilized to explain infectious ailments the place the first mode of transmission includes the pathogen touring by or being suspended within the air, much like the usage of phrases like “waterborne” ailments, that are broadly understood throughout varied fields and by most of the people.
The brand new definition was developed with enter from practically 500 consultants, together with physicists, public well being professionals, and engineers, a lot of whom had beforehand engaged in heated debates on the topic. Traditionally, companies have demanded excessive ranges of proof earlier than classifying ailments as airborne, which necessitated strict containment measures. The brand new definition takes under consideration the danger of publicity and the severity of the illness, along with the proof of airborne transmission.
Earlier disagreements amongst consultants centered across the classification of infectious particles as both “droplets” or “aerosols” primarily based on their dimension, a distinction that the brand new definition strikes away from. Throughout the early phases of the COVID-19 pandemic in 2020, roughly 200 aerosol scientists publicly criticized the WHO for failing to adequately warn individuals concerning the danger of airborne transmission of the virus. They argued that this led to an overemphasis on measures like handwashing, fairly than specializing in air flow, to forestall the unfold of the virus.
