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.

Meeting Report 27-29 October 2020
The overall goal of the meeting was to discuss recent changes in treatment regimens and diagnostics for drug-resistant TB and to determine how these impact on the definition of XDR-TB, with a view to revising this definition. The pre-existing definition of XDR-TB w...as formulated in 2006 at a meeting of the Global Taskforce on XDR-TB, convened by WHO, and has been in use for clinical and surveillance purposes, since this time.

The emergence of COVID-19 has drawn the attention of health researchers sharply back to the role that food systems can play in generating human disease burden. But emerging pandemic threats are just one dimension of the complex relationship between agriculture... and infectious disease, which is evolving rapidly, particularly in low-income and middle-income countries (LMICs) that are undergoing rapid food system transformation. This changing relationship is examined through four current disease issues.

Event-based surveillance (EBS) is defined as the organized collection, monitoring, assessment and interpretation of mainly unstructured ad hoc information regarding health events or risks, which may represent an acute risk to health. Both indicator-based and event-based surveillance components serve... the early warning and response (EWAR) function of the public health surveillance system. The Framework for Event-based Surveillance offers guidance to public health practitioners seeking to implement EBS at each administrative level in their countries.

Healthcare-associated infections (HAI) are a significant burden globally, with millions of patients affected each year. These infections affect both high- and limited-resource healthcare settings, but in limited-resource settings, rates are approximately twice as high as high-resource settings (15 o...ut of every 100 patients versus 7 out of every 100 patients). Furthermore, rates of infections within certain patient populations are significantly higher in limited-resource settings, including surgical patients, patients in intensive-care units (ICU) and neonatal units. It is well documented that environmental contamination plays a role in the transmission of HAIs in healthcare settings. Therefore, environmental cleaning is a fundamental intervention for infection prevention and control (IPC).It is a multifaceted intervention that involves cleaning and disinfection (when indicated) of the environment alongside other key program elements to support successful implementation (e.g., leadership support, training, monitoring, and feedback mechanisms). To be effective, environmental cleaning activities must be implemented within the framework of the facility IPC program, and not as a standalone intervention. It is also essential that IPC programs advocate for and work with facility administration and government officials to budget, operate and maintain adequate water, sanitation and hygiene (WASH) infrastructure to ensure that environmental cleaning can be performed according to best practices.
