Medical devices are used for the prevention, diagnosis and treatment of illness and diseases and for rehabilitation. WHO developed guidance on medical device donation in 2011, which has been now reviewed, with new evidence, new references on considerations for medical device solicitation and provisi...on, risks associated with inappropriate donations, the responsibilities of donors and recipient, and the steps they should follow before, during and after a donation. It includes three sections: description of major problems that may be faced during the donation process, listing of best practices for donors and recipients and addressing situations requiring special attention. It also has three annexes for further reading: the criteria for the acceptability of a donation, literature review on donations of medical devices between 2010 and 2023 and a flyer. This document is intended to improve the quality of medical devices donations, including medical equipment, single-use medical devices and in-vitro diagnostics, to provide maximum benefit to all stakeholders. The considerations can be used to develop institutional or national policies and regulations for medical devices donations. This document is intended for use by any organization, expert or practitioner involved in the donation, procurement, management of medical devices, including health workers, biomedical engineers, health managers, policymakers, donors, nongovernmental organizations and academic institutions.

Small drinking-water supplies commonly experience operational, managerial, technical and resourcing challenges that impact their ability to deliver safe and reliable services. The needs and opportunities associated with these supplies therefore warrant explicit consideration in policies and regulati...ons.
These Guidelines, specifically tailored to small water supplies, build on over 60 years of guidance by the World Health Organization (WHO) on drinking-water quality and safety. They focus on establishing drinking-water quality regulations and standards that are health based and context appropriate; on proactively managing risks through water safety planning and sanitary inspections; and on carrying out independent surveillance. The guidance is intended primarily for decision-makers at national and subnational levels with responsibility for developing regulatory frameworks and support programmes related to these activities. Other stakeholders involved in water service provision will also benefit from the guidance in this document.
Designed to be practical and accessible, these Guidelines offer clear guidance that is rooted in the principle of progressive improvement. State-of-the-art recommendations and implementation guidance are provided, drawn from a comprehensive evidence review and established good practices. Additionally, case examples are provided from countries and areas around the world to demonstrate how the guidance in this publication has been implemented in practice in a wide variety of contexts.
Together with WHO’s 2024 Sanitary inspection packages – a supporting tool for the Guidelines for drinking-water quality: small water supplies, these Guidelines update and supersede WHO’s 1997 Guidelines for drinking-water quality. Volume 3: surveillance and control of community supplies. Key changes to this updated publication include a greater focus on preventive risk management and a broader range of small water supplies covered, including those managed by households, communities and professional entities.

During the 17 years since Surgical approaches to the urogenital manifestations of lymphatic filariasis was first published, there has been heightened awareness of the physical, economic and emotional burden of the genitourinary manifestations of filariasis. With the impetus to provide better guidanc...e for care of those suffering from LF, this update was both warranted and timely.
At the outset, the Committee noted that barriers continue to exist in care of patients affected by LF-associated morbidity. These barriers include lack of information for patients as well as for many healthcare providers, including general surgeons and others within health systems
This update offers a new consensus of the Committee regarding the staging of hydroceles caused by LF, also known as “filariceles”. It recommends integrating LF surgery with other efforts to strengthen surgical care by assessing health facilities for their surgical readiness using the WHO surgical assessment tool or “SAT”. It also recommends integratinghernia surgery with hydrocele surgery and integrating standards for prevention of surgical site infection (SSI).
The update revises recommendations for standard procedures and processes, offers an algorithm for diagnosis (including the use of ultrasound) and discusses postoperative care. It recommends collecting data using the staging and grading system described by Capuano and Capuano along with other metrics for public health management of LF.
A multifaceted approach has therefore been recommended to coordinate public health outreach with national surgical planning and local health systems to include supporting partners such as nongovernmental organizations. Surgical camps with mobile teams, as well as training of personnel at DCP3 “first level” or WHO Level II hospitals (depending on region and resources), have important roles for reducing LF morbidity.

Chagas heart disease (CHD) affects approximately 30% of patients chronically infected with the protozoa Trypanosoma cruzi. CHD is classified into four stages of increasing severity according to electrocardiographic, echocardiographic, and clinical criteria. CHD presents with a myriad of clinical man...ifestations, but its main complications are sudden cardiac death, heart failure, and stroke. Importantly, CHD has a higher incidence of sudden cardiac death and stroke than most other cardiopathies, and patients with CHD complicated by heart failure have a higher mortality than patients with heart failure caused by other etiologies. Among patients with CHD, approximately 90% of deaths can be attributed to complications of Chagas disease. Sudden cardiac death is the most common cause of death (55%-60%), followed by heart failure (25%-30%) and stroke (10%-15%). The high morbimortality and the unique characteristics of CHD demand an individualized approach according to the stage of the disease and associated complications the patient presents with. Therefore, the management of CHD is challenging, and in this review, we present the most updated available data to help clinicians and cardiologists in the care of these patients. We describe the clinical manifestations, diagnosis and classification criteria, risk stratification, and approach to the different clinical aspects of CHD using diagnostic tools and pharmacological and non-pharmacological treatments.

Leishmaniasis is a major vector-borne disease caused by obligate intramacrophage protozoa of the genus Leishmania, and transmitted by the bite of phlebotomine female sand flies of the genera Phlebotomus and Lutzomyia, in the old and new worlds, respectively. Among 20 well-recognized Leishmania speci...es known to infect humans, 18 have zoonotic nature, which include agents of visceral, cutaneous, and mucocutaneous forms of the disease, in both the old and new worlds. Currently, leishmaniasis show a wider geographic distribution and increased global incidence. Environmental, demographic and human behaviors contribute to the changing landscape for zoonotic cutaneous and visceral leishmaniasis. The primary reservoir hosts of Leishmania are sylvatic mammals such as forest rodents, hyraxes and wild canids, and dogs are the most important species among domesticated animals in the epidemiology of this disease. These parasites have two basic life cycle stages: one extracellular stage within the invertebrate host (phlebotomine sand fly), and one intracellular stage within a vertebrate host. Co-infection with HIV intensifies the burden of visceral and cutaneous leishmaniasis by causing severe forms and more difficult to manage. The disease is endemic to Ethiopia, and the clinical signs are not pathognomic. The visceral form (Kala-azar) may be confused with other similar conditions such as malaria, tropical splenomegaly, schistosomiasis, milliary tuberculosis, and brucellosis. Similarly, cutaneous leishmaniasis should be differentiated from disease like tropical ulcers, impetigo and leprosy. There are several methods of laboratory diagnosis of leishmaniasis, including parasitological, immunological and molecular. Different forms of treatments are available including oral, parenteral, and topical medications such as pentavalent antimonials, liposomal amphotericin B, miltefosine and paromomycin. Methods of control are largely limited to destruction of animal reservoirs, treatment of infected humans, and management of sand fly populations. Development of an effective vaccine against leishmaniasis has been largely unsuccessful and hinders its prevention.

To eliminate lymphatic filariasis (LF) by 2020, the World Health Organization (WHO) has launched a campaign against the disease. Since the launch in 2000, significant progress has been made to achieve this ambitious goal. In this article we review the progress and status of the LF programme in Afric...a through the WHO neglected
tropical diseases preventive chemotherapy databank, the Expanded Special Project for Elimination of Neglected Tropical Diseases (ESPEN) portal and other publications. In the African Region there are 35 countries endemic for LF. The Gambia was reclassified as not requiring preventive chemotherapy in 2015, while Togo and Malawi eliminated LF as a public health problem in 2017 and 2020, respectively. Cameroon discontinued mass drug administration (MDA) and transitioned to post-MDA surveillance to validate elimination. The trajectory of coverage continues to accelerate; treatment coverage increased from 0.1% in 2000 to 62.1% in 2018. Geographical coverage has also significantly increased, from 62.7% in 2015 to 78.5% in 2018. In 2019, 23 of 31 countries requiring MDA achieved 100% geographic coverage. Although much remains to be done, morbidity management and disability prevention services have steadily increased in recent years. Vector control interventions conducted by other programmes, particularly malaria vector control, have had a profound effect in stopping transmission in some endemic countries in the region. In conclusion, significant progress has been made in the LF programme
in the region while we identify the key remaining challenges in achieving an Africa free of LF.

In South and Central America, lymphatic filariasis (LF) is caused by Wuchereria bancrofti, which is transmitted by Culex quinquefasciatus, the only vector species in this region. Of the seven countries considered endemic for LF in the Americas in the last decade, Costa Rica, Suriname and Trinidad a...nd Tobago were removed from the World Health Organization list in 2011. The remaining countries, Brazil, Dominican Republic, Guyana and Haiti, have achieved important progress in recent years. Brazil was the first country in the Americas to stop mass drug administration (MDA) and to establish post-MDA surveillance. Dominican Republic stopped MDA in all LF-endemic foci: La Ciénaga and Southwest passed the third Transmission Assessment Survey (TAS) and the Eastern focus passed TAS-1 in 2018. Haiti passed the TAS and interrupted transmission in >80% of endemic communes, achieving effective drug coverage. Guyana implemented effective coverage in MDAs in 2017 and 2018 and in 2019 scaled up the treatment for 100% of the geographical region, introducing ivermectin in the MDA in order to achieve LF elimination by the year 2026. The Americas region is on its way to eliminating LF transmission. However, efforts should be made to improve morbidity management to prevent disability of the already affected populations.

This publication presents the Agenda for the Americas on Health, Environment, and Climate Change 2021–2030 (the Agenda). The Agenda is a call to action to the health sector to lead the charge to address environmental determinants of health in the Americas. The Pan American Health Organization (PAH...O) will work with Member States to achieve its goal and objective to ensure healthy lives and promote well-being for all at all ages using a sustainable and equitable approach that places a priority on reducing health inequity. The Agenda has been developed under the umbrella of the WHO Global Strategy on Health, Environment, and Climate Change, and builds upon the commitments set forth in the Sustainable Health Agenda for the Americas 2018–2030 and the PAHO Strategic Plan 2020–2025. The Agenda was developed in consultation with the Technical Advisory Group and through a consensus-driven decision-making process with Member States during the 2019–2020 period. Looking toward the achievement of Sustainable Development Goal 3, the Agenda focuses on: improving the performance of environmental public health programs and institutions; fostering environmentally resilient and sustainable health systems; and promoting environmentally healthy and resilient cities and communities. Its implementation will be context-specific, based on the needs and realities of the countries. It will benefit countries and territories by promoting good governance practices, strengthening the leadership and coordination roles of the health sector, fostering cross-sectoral action, focusing on primary prevention, and enhancing evidence and communication. It will facilitate access to human, technical, and financial resources necessary to address environmental determinants of health and ensure that the Region is fully engaged in global health, environment, and climate change processes and agreements. The objective of the Agenda is to strengthen the capacity of health actors in the health and non-health sectors to address and adapt to environmental determinants of health (EDHs), prioritizing populations living in conditions of vulnerability, in order to meet Outcome 18 of the PAHO Strategic Plan 2020–2025 directly and several other outcomes of the Plan indirectly. To address and adapt to the challenges of EDHs in the Region, an integrated and evidence-informed approach within the health sector and across sectors will be needed, one enabled, and supported by good governance practices, adequate management mechanisms, high-level political will, and adequate human, technical, technological, and financial resources.

In the face of rapid increases in the number of hospitalizations due to COVID-19 in Latin America and the Caribbean, coupled with shortages of human and material resources, including medical equipment and gases, there is a need to redesign models of care in the Region to optimize available resources... and ensure that more patients receive the quantity and quality of oxygen they need. Oxygen is included in the World Health Organization’s list of essential medicines and is used to care for patients at all levels of integrated health services networks. The efficacy of oxygen use in the treatment of patients with respiratory conditions caused by COVID-19 has been demonstrated, but there is great opportunity to improve the effectiveness of its use if it is used in a rational, sustainable, and safe way. Bearing in mind that the efficacy of a health technology is measured by its benefit under actual conditions of use, practical actions can be taken to improve the use of medical oxygen and avoid oxygen shortages. A drug is considered to be used rationally when patients receive it according to their clinical needs, in doses appropriate to their individual needs, for an appropriate period, and at a low cost to them and their community. By providing instruction on the rational use of oxygen and promoting it, negative repercussions can be avoided, such as loss of efficacy as a result of activities related to oxygen storage, distribution, and administration. Rational use of oxygen also involves controlling waste due to leaks in storage and distribution systems, use of gas at incorrect pressures, use of incorrectly adjusted flowmeters, and disconnections, among other problems. Another aspect to consider is the provision of adequate technical support for all oxygen production systems, in terms of maintenance and calibration, availability of electrical energy, and specific knowledge about these systems. For these reasons, a set of guidelines has been put together for the development of an efficient management system to deal with situations of oxygen scarcity, both now and in the future.

The COVID-19 pandemic has affected job satisfaction among healthcare workers; yet this has not been empirically examined in sub-Saharan Africa (SSA). We addressed this gap by examining job satisfaction and associated factors among healthcare workers in Ghana and Kenya during the COVID-19 pandemic. W...e conducted a cross-sectional study with healthcare workers (N = 1012). The two phased data collection included: (1) survey data collected in Ghana from April 17 to May 31, 2020, and (2) survey data collected in Ghana and Kenya from November 9, 2020, to March 8, 2021. We utilized a quantitative measure of job satisfaction, as well as validated psychosocial measures of perceived preparedness, stress, and burnout; and conducted descriptive, bivariable, and multivariable analysis using ordered logistic regression. We found high levels of job dissatisfaction (38.1%), low perceived preparedness (62.2%), stress (70.5%), and burnout (69.4%) among providers. High perceived preparedness was positively associated with higher job satisfaction (adjusted proportional odds ratio (APOR) = 2.83, CI [1.66,4.84]); while high stress and burnout were associated with lower job satisfaction (APOR = 0.18, CI [0.09,0.37] and APOR = 0.38, CI [0.252,0.583] for high stress and burnout respectively). Other factors positively associated with job satisfaction included prior job satisfaction, perceived appreciation from management, and perceived communication from management. Fear of infection was negatively associated with job satisfaction. The COVID-19 pandemic has negatively impacted job satisfaction among healthcare workers. Inadequate preparedness, stress, and burnout are significant contributing factors. Given the already strained healthcare system and low morale among healthcare workers in SSA, efforts are needed to increase preparedness, better manage stress and burnout, and improve job satisfaction, especially during the pandemic.

Primary health care offers a cost–effective route to achieving universal health coverage (UHC). However, primary health-care systems are weak in many low- and middle-income countries and often fail to provide comprehensive, people-centred, integrated care. We analysed the primar...y health-care systems in 20 low- and middle-income countries using a semi-grounded approach. Options for strengthening primary health-care systems were identified by thematic content analysis. We found that: (i)despite the growing burden of noncommunicable disease, many low- and middle-income countries lacked funds for preventive services; (ii)community health workers were often under-resourced, poorly supported and lacked training; (iii)out-of-pocket expenditure exceeded 40% of total health expenditure in half the countries studied, which affected equity; and (iv)health insurance schemes were hampered by the fragmentation of public and private systems, underfunding, corruption and poor engagement of informal workers. In 14 countries, the private sector was largely unregulated. Moreover, community engagement in primary health care was weak in countries where services were largely privatized. In some countries, decentralization led to the fragmentation of primary health care. Performance improved when financial incentives were linked to regulation and quality improvement, and community involvement was strong. Policy-making should be supported by adequate resources for primary health-care implementation and government spending on primary health care should be increased by at least 1% of gross domestic product. Devising equity-enhancing financing schemes and improving the accountability of primary health-care management is also needed. Support from primary health-care systems is critical for progress towards UHC in the decade to 2030.

This chapter reviews the emerging importance of pollen allergies in relation to ongoing climate change. Allergic diseases have been increasing in prevalence over the last decades, partly as the result of the impact of climate change. ...Increased sensitisation rates and more severe symptoms have been the partial outcome of: increased pollen production of wind-pollinated plants resulting in long-term increased abundance of pollen in the air we breathe; earlier shifts of airborne pollen seasons making occurrence of allergic symptoms harder to predict and deal with efficiently; increased allergenicity of pollen causing more severe health effects in allergic individuals; introduction of new, invasive allergenic plant species causing new sensitisations; environment-environment interactions, such as plants and hosted microorganisms, i.e. fungi and bacteria, which comprise a complex and dynamic system, with additive, presently unforeseeable influences on human health; environment-human interactions, as the consequence of a combination of environmental factors, like air pollution, global warming, urbanisation and microclimatic variability, which create a multi-resolution spatiotemporal system that requires new processing technologies and huge data inflow in order to be thoroughly investigated. We suggest that novel, real-time, personalised pollen information services, like mobile-app risk alerts, must be developed to provide the optimum first line of allergy management.
