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.

Asthma is the most common noncommunicable disease in children, and among the most common in adults. According to the most recent estimates from the Global Asthma Network Phase I study, around one in 10 children and adults have symptoms of asthma and one in 20 school-aged children have severe asthma ...symptoms, with marked variations in prevalence and in prevalence trends between countries and regions of the world. The Global Burden of Disease Study estimated that asthma caused the loss of 21.6 million healthy years of life (disability-adjusted life years) and 461 069 deaths in 2019. Approximately 90% of the asthma burden of disease is borne by people living low and middle income countries (LMICs). Some countries report very high (up to 90%) rates of uncontrolled asthma. While the prevalence of asthma is highest in countries with a high Socio-Demographic Index (SDI), death rates from asthma are highest in countries with low and lower middle incomes.

Antimicrobial resistance is a global crisis that threatens a century of progress in health and achievement of the Sustainable Development Goals. There is no time to wait. Unless the world acts urgently, antimicrobial resistance will have disastrous impact within a generation.
The WHO End TB Strategy aims to end the global TB epidemic by 2030, in alignment with Goal 3 of the United Nations (UN) Sustainable Development Goals (SDGs). Member States of the World Health Organi...zation (WHO) and the UN committed to ending the TB epidemic through adoption of WHO’s End TB Strategy and the UN SDGs in 2014 and 2015, respectivel
Almost half of the deaths worldwide caused by TB in 2019 occurred in the WHO South-East Asia Region, home to around a quarter of the global population. Maintaining robust progress in this Region is therefore essential if the global goal of ending the TB epidemic is to be realized. Despite substantial gains made in the Region, the threat to
health worldwide posed by the COVID-19 pandemic has the potential to reverse these gains and eclipse the focus on the global TB emergency.
While continuing to tackle COVID-19-related challenges, countries will need to rapidly and urgently deploy supplementary measures to address the large numbers of missed cases, poor treatment outcomes and, potentially, a higher TB burden.
The Regional Strategic Plan towards Ending TB in the Region 2021–2025 clearly articulates priority interventions, analyses the challenges, bottlenecks and opportunities, and focuses on implementation considerations in the Region.
