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.

This report summarizes application of the SAFE strategy against trachoma during 2024. It includes estimates of the global population at risk of trachoma blindness based on district-by-district data submitted to WHO by national programmes.
Caring for burns patients from the incident scene to definitive treatment can be a complex, resource-consuming process with the potential to overwhelm health system capacity.This document provides practical guidance for building capacity and capability for burns care from clinical, human resources a...nd operational perspectives. It is therefore recommended that guidance in this document be applied to any contexts in which the local health system might struggle to cope and require surge support.

First Global Patient Safety Challenge Clean Care is Safer Care
The WHO Guidelines on Hand Hygiene in Health Care provide health-care workers (HCWs), hospital administrators and health authorities with a thorough review of evidence on hand hygiene in health care and specific recommendations to impro...ve practices and reduce transmission of pathogenic microorganisms to patients and HCWs. The present Guidelines are intended to be implemented in any situation in which health care is delivered either to a patient or to a specific group in a population. Therefore, this concept applies to all settings where health care is permanently or occasionally performed, such as home care by birth attendants.

Looking forward, the 2019-2020 Regional Refugee Response Plan (RRRP) for the DRC situation aims at addressing the needs of new arrivals of Congolese refugees in the region, and those in protracted situations. By supporting livelihoods opportunities and through a resilience-based approach, refugees w...ill be able to contribute to the development of their host countries, and of their country of origin upon their return. Given the limited capacity of host communities to support the impact of massive numbers of refugees, the response strategy will also address the needs of local populations, strengthening peaceful co-existence and building social cohesion.

Humanitarian emergencies and crises (Humanitarian emergencies and crises) are large-scale events that may result in the breakdown of health care systems and society, forced displacement, death, and physical, psychological, social and spiritual suffering on a massive scale. Current responses to Human...itarian emergencies and crises rightfully focus on saving lives, but for both ethical and medical reasons, the prevention and relief of pain, as well as other physical and psychological symptoms, social and spiritual distress, also are imperative. Therefore, palliative care, should be integrated into responses to Humanitarian emergencies and crises. The principles of humanitarianism and impartiality require that all patients receive care and should never be abandoned for any reason, even if they are dying. Thus, there is significant overlap in the principles and mission of palliative care and humanitarianism: relief of suffering; respect for the dignity of all people; support for basic needs; and accompaniment during the most difficult of times

This guideline aims to improve the quality of donations and the management thereof and serve as the basis for policies of the State and other organizations in the giving and receiving of donations of medicines, medical devices and IVDs.
Over the last three or four decades, there has been an enorm...ous increase in scientific knowledge about the mode of action, effects and side effects of medicines, medical devices and IVDs. It is important for all
stakeholders to understand that these products have both benefits and risks, that they have to be used carefully and appropriately and that some can do more harm than good.
There are many different scenarios for the donation of medicines, medical devices and IVDs. Donations may take place in acute emergencies or as part of development aid in non-emergency situations. They may involve donations (i.e. direct or through private voluntary organizations), aid by governments or persons authorized to sell medicines, medical devices and/or IVDs.

The active participation and engagement of health and care workers (HCWs) in health emergency preparedness, readiness and response is crucial to support risk communication, community engagement and infodemic management (RCCE-IM) interventions during emergencies. HCWs hold unique position...s in society – repeatedly being identified among the main influencers of people’s behaviours: they are one of the most trusted sources of health information and advice in communities and role models for the acceptance and uptake of protective measures during health emergencies. On the frontline, HCWs have valuable insights and knowledge that can be harnessed to support health emergencies across the entire emergency cycle. Between October and December 2023, the WHO Regional Office for Europe interviewed key informants on strategies and experiences to meaningfully engage HCWs during emergencies
