This is the second edition of the WHO handbook on the safe, sustainable and affordable management of health-care waste--commonly known as "the Blue Book". The original Blue Book was a comprehensive publication used widely in health-care centers and government agencies to assist in the adoption of national guidance. It also provided support to committed medical directors and managers to make improvements and presented practical information on waste-management techniques for medical staff and waste workers. It has been more than ten years since the first edition of the Blue Book. During the intervening period, the requirements on generators of health-care wastes have evolved and new methods have become available. Consequently, WHO recognized that it was an appropriate time to update the original text. The purpose of the second edition is to expand and update the practical information in the original Blue Book. The new Blue Book is designed to continue to be a source of impartial health-care information and guidance on safe waste-management practices. The editors' intention has been to keep the best of the original publication and supplement it with the latest relevant information. The audience for the Blue Book has expanded. Initially, the publication was intended for those directly involved in the creation and handling of health-care wastes: medical staff, health-care facility directors, ancillary health workers, infection-control officers and waste workers. This is no longer the situation. A wider range of people and organizations now have an active interest in the safe management of health-care wastes: regulators, policy-makers, development organizations, voluntary groups, environmental bodies, environmental health practitioners, advisers, researchers and students. They should also find the new Blue Book of benefit to their activities. Chapters 2 and 3 explain the various types of waste produced from health-care facilities, their typical characteristics and the hazards these wastes pose to patients, staff and the general environment. Chapters 4 and 5 introduce the guiding regulatory principles for developing local or national approaches to tackling health-care waste management and transposing these into practical plans for regions and individual health-care facilities. Specific methods and technologies are described for waste minimization, segregation and treatment of health-care wastes in Chapters 6, 7 and 8. These chapters introduce the basic features of each technology and the operational and environmental characteristics required to be achieved, followed by information on the potential advantages and disadvantages of each system. To reflect concerns about the difficulties of handling health-care wastewaters, Chapter 9 is an expanded chapter with new guidance on the various sources of wastewater and wastewater treatment options for places not connected to central sewerage systems. Further chapters address issues on economics (Chapter 10), occupational safety (Chapter 11), hygiene and infection control (Chapter 12), and staff training and public awareness (Chapter 13). A wider range of information has been incorporated into this edition of the Blue Book, with the addition of two new chapters on health-care waste management in emergencies (Chapter 14) and an overview of the emerging issues of pandemics, drug-resistant pathogens, climate change and technology advances in medical techniques that will have to be accommodated by health-care waste systems in the future (Chapter 15).

This book deals with the general principles, policy instruments, sustainability of supply chain, and business of health-care waste (HCW) management including inputs on exercise in immune health defense against COVID 19. Health-care waste management is very important in any country for protection of environmental and animal and human health. The COVID-19 pandemic, in addition, has augmented this importance to a greater extent. Italy has been successful in curbing the problems related to HCW management during the COVID-19 pandemic at very fast rates from the worst situation, while for a few countries in Asia and Africa, challenges still exist. It is necessary that policy makers, researchers, and implementers gain more knowledge and information on these aspects and improve the strategies and actions. Addressing these issues will reduce the cost of health care as well as resource inefficiency hindering sustainable development goals. This book is of interest and useful to practitioners, capacity builders and policy makers, entrepreneurs, NGOs, and general people, and is a valuable source of reference to the relevant researchers and students in global markets. The book serves as a reading material for undergraduate and graduate students of environmental science, waste management, and medical science. National and international scientists as well as policy makers will also find this to be a useful read. .

This book highlights the impact of COVID-19 on sustainable waste management and air emission, using various case studies. The year 2020 was a historical year mainly due to the pandemic caused by COVID-19 and it influenced or affected the global economy, business models and the industrial sectors, thus impacting sustainability in various ways. Given that sustainability has many faces and facets, it is worthwhile to deal with the relation (or impact) of COVID-19 on various elements of sustainability. This book presents how COVID-19 has influenced waste management and air quality.

The COVID-19 pandemic has caused unprecedented disruption worldwide highlighting once again the interdependency of health and socioeconomic development, and the global lack of health systems resilience. Two years into the pandemic, most countries report sustained disruptions across service delivery platforms and health areas with a profound impact on health outcomes. The impact of these disruptions is magnified within marginalized communities and in countries experiencing protracted conflict. There is an urgent need to focus on recovery through investment in the essential public health functions (EPHFs) and the foundations of health systems with a focus on primary health care, and whole-of-government and -society engagement. The aim of this Research Topic is to gather, transfer and promote operationalization of key experiences from COVID-19 to inform global and country level recovery that better promote health; guide policy direction towards building health systems resilience; and thereby ensure economic and social prosperity. Experience with COVID-19 has demonstrated that traditional approaches to health system strengthening have failed to achieve the complementary goals of Universal Health Coverage (UHC) and health security with the divide between the most vulnerable and well-off only widening. Much of what had been learned from previous experiences such as Ebola in West Africa has not been widely applied. This has left health and economic systems vulnerable to 21 st century public health challenges, ranging from conflict and natural disasters to aging demographics and rising rates of non-communicable and communicable diseases and antimicrobial resistance. These challenges require intentional focus and investment as well as whole-of-government and -society engagement with health to build health system resilience. Greater action is needed to prevent the devastating effects of war and conflict on the health of the most vulnerable. This Research Topic will convene the knowledge and practices of leaders in public health, health systems, and humanitarian and development sectors. This is to ensure lessons from COVID-19 inform the recovery agenda and promote sustainable health and socioeconomic recovery for all. Lest we forget and find ourselves again unprepared and vulnerable in the face of an even greater threat.

This report summarizes the World Health Organization’s (WHO) global work on water, sanitation and hygiene (WASH) during 2022. It describes WHO’s continued delivery of essential WASH programming as elaborated in its 2018–2025 strategy. This includes publication and dissemination of its work monitoring access to WASH and WASH systems through the WHO/UNICEF Joint Monitoring Programme for Water Supply, Sanitation and Hygiene (JMP) and the UN-Water Global Analysis and Assessment of Sanitation and Drinking-Water (GLAAS), continued development and implementation of its norms on drinking-water and sanitation, and overall advocacy including on hand hygiene. All of WHO’s WASH work was augmented through the strength of its partnerships.
