In this version of the compendium, each guidance is coded using the International Classification of Health Interventions (ICHI).
The compendium provides a systematic compilation of published guidance from WHO and other UN organizations on health and environment. Guidance on policies and actions a...s well as awareness raising and capacity building interventions is presented for all major areas of health and environment. Guidance referring to priority settings for action such as cities and other urban settlements, housing, workplaces and health care facilities is also listed. For greater practical relevance, each guidance is classified according to principally involved sectors, level of implementation and instruments for implementation.
The compilation of guidance for each area of health and environment or priority setting for action is accompanied, as available, by information on main sources, exposure assessment and existing guideline values. Important tools and further resources are presented alongside.
This compilation of published guidance on health and environment highlights that a large number of actions across main topics of health and environment, concerning various sectors, and applicable to various levels are available to improve health and reduce environmental risks. This compendium is intended to serve as a repository and easy-to-use and useful resource for decision and policy makers in health and environment at various levels.

Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.

As the Americas undergo profound demographic change and there are more persons aged 65 years or older than children younger than 5 years, it is crucial to recognize that national immunization programs must be redesigned to ensure comprehensive protection for individuals across the lifespan. By adopt...ing a life course approach (LCA) to immunization, vaccination programs can be tailored to close immunity gaps at different stages of life. The life course approach foresees the establishment of multiple strategies to reduce missed opportunities for vaccination according to age group. This technical document explains the key concepts of the LCA with a focus on immunization by vaccination, as well as the underlying biological mechanisms that require the application different vaccines at different life stages according to changes to the immune system and in the epidemiological situation of a community.

Through technical consultations with countries and partners, WHO has led the development of Preparedness and Resilience for Emerging Threats Module 1: Planning for respiratory pathogen pandemics. Version 1.0. The Module, currently available as an advanced draft, builds on previous pandemic lessons a...nd guidance, and has the following new elements:
It presents an integrated and efficient respiratory pathogen pandemic planning approach covering both novel pathogens and those known to have pandemic potential;
It enables coherence in addressing pathogen-agnostic and pathogen-specific elements for better preparedness;
It gives an organizing framework including operational stages and triggers for escalation and de-escalation between pandemic preparedness and response periods;
It contextualizes 12 IHR (2005) core capacities within the five components of health emergency preparedness, response and resilience (HEPR), from the respiratory threats perspective; and
It describes the critical sectors for respiratory pathogen pandemic preparedness to trigger multisectoral collaboration.
WHO will finalize and publish this Module after a global technical meeting that will be held on 24-26 April 2023.

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.

Ahead of World Malaria Day, the WHO Global Malaria Programme published a new operational strategy outlining its priorities and key activities up to 2030 to help change the trajectory of malaria trends, with a view to achieving the global malaria targets. The strategy outlines 4 strategic objectives ...where WHO will focus its efforts, including developing norms and standards, introducing new tools and innovation, promoting strategic information for impact, and providing technical leadership of the global malaria response.
In recent years, progress towards critical targets of the WHO Global technical strategy for malaria 2016-2030 has stalled, particularly in countries that carry a high burden of the disease. In 2022 there were an estimated 608 000 malaria-related deaths and 249 million new malaria cases globally, with young children in Africa bearing the brunt of the disease.
Millions of people continue to miss out on the services they need to prevent, detect, and treat malaria. Additionally, progress in global malaria control has been hampered by resource constraints, humanitarian crises, climate change and biological threats such as drug and insecticide resistance.
“A shift in the global malaria response is urgently needed across the entire malaria ecosystem to prevent avoidable deaths and achieve the targets of the WHO global malaria strategy,” notes Dr Daniel Ngamije, Director of the Global Malaria Programme. “This shift should seek to address the root causes of the disease and be centred around accessibility, efficiency, sustainability, equity and integration.”

Smallpox eradication was certified in 1980. Mpox has been endemic in Central and West African countries since it was first detected in 1958 . It is a zoonosis; cases are often found close to tropical rainforests where various animals carry the orthopoxvirus that causes the disease. In endemic countr...ies, most mpox infections in humans result from a primary animal-to-human transmission. Human-to-human transmission can result from close contact with respiratory secretions, skin lesions of an infected person, or recently contaminated objects. Transmission can also occur via the placenta from mother to fetus or through close contact during and after birth.
