Terminology used to describe the transmission of pathogens through the air varies across scientific disciplines, organizations and the general public. While this has been the case for decades, during the coronavirus disease (COVID-19) pandemic, the terms ‘airborne’, ‘airborne transmission’ a
...
nd ‘aerosol transmission’ were used in different ways by stakeholders in different scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations.
This global technical consultation report brings together viewpoints from experts spanning a range of disciplines with the key objective of seeking consensus regarding the terminology used to describe the transmission of pathogens through the air that can potentially cause infection in humans.
This consultation aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities. Despite the complex discussions and challenges, significant progress was made during the consultation process, particularly the consensus on a set of descriptors to describe how pathogens are transmitted through the air and the related modes of transmission. WHO recognizes the important areas where consensus was not achieved and will continue to address these areas in follow-up consultations.

For thousands of years, humans have been using wildlife for commercial and subsistence purposes. Wildlife trade takes place at local, national and international levels, with different forms of wildlife, such as live animals, partly processed products and finished products. Wildlife is a vital source
...
of safe and nutritious food, clothing, medicine, and other products, in addition to having religious and cultural value. Wildlife trade also contributes to livelihoods, income generation and overall economic development.
However, wildlife trade can have detrimental effects on species conservation, depleting natural resources, impoverishing biodiversity and degrading ecosystems (Morton et al., 2021). Wildlife trade, whether legal or illegal, regulated or unregulated, can pose threats to animal health and welfare. It also presents opportunities for zoonotic pathogens to spill over between wildlife and domestic animals, and for diseases to emerge with serious consequences for public or animal health and profound economic impacts (IPBES, 2020; Swift et al., 2007; Smith et al., 2009; Gortazar et al., 2014; Stephen, 2021; Stephen et al., 2022; FAO, 2020). The risk of pathogen spillover and disease emergence is amplified with increased interaction between humans, wildlife and domestic animals. The risk of pathogen spillover has also been exacerbated by climate change, intensified agriculture and livestock production, deforestation, and other land-use changes. Wildlife trade is also a risk to ecosystem biodiversity via the introduction of invasive species (Wikramanayake et al., 2021). Therefore, increased effort must be put into understanding the potential consequences of the wildlife trade, mapping and analysing the adjacent risks, and implementing strategies to manage those risks. Reducing wildlife-trade risks not only helps to limit disease but also minimises the negative effects of invasive species. Between 1960 and 2021, invasive alien species caused estimated cumulative damage of around 116 billion euros across 39 countries in the European Union alone, despite strict import regulations (Haubrock et al., 2021). The effect of invasive species is extremely apparent.
