Global temperatures and the frequency and intensity of heatwaves will rise in the 21st century as a result of climate change. Extended periods of high day and nighttime temperatures create cumulative physiological stress on the human body which exacerbates the top causes of death globally, including... respiratory and cardiovascular diseases, diabetes mellitus and renal disease. Heatwaves can acutely impact large populations for short periods of time, often trigger public health emergencies, and result in excess mortality, and cascading socioeconomic impacts

Each humanitarian setting provides distinct opportunities and challenges for actors to coordinate and collaborate at strategic and operational levels. The Health and Protection Joint Operational Framework has been developed to ensure that the health and protection response during humanitarian emerge...ncies can adapt to each environment and is adequately coordinated to ensure high-quality services to meet the needs of affected individuals and at-risk groups based on their situation or vulnerabilities.
The Health and Protection JOF was conceived in 2019 as a collaboration between the Global Health Cluster (GHC), the Global Protection Cluster (GPC) and its Areas of Responsibility (AoRs), the Inter-Agency Standing Committee Reference Group on Mental Health and Psychosocial Support in Emergency Settings (IASC MHPSS RG), and the Inter-Agency Working Group for Reproductive Health in Crisis (IAWG), in addition to key technical experts.
A Steering Group (SG) comprised of representatives from each of these entities guided the framework through a joint global analysis of good practices, gaps, and barriers to integrated and inter-sectoral response coordination. This included a mixed methods review of policy and practice, a survey of humanitarian experts, multiple case studies, structured stakeholder interviews, and field visits. This exercise produced a zero-draft which was then reviewed by field practitioners in three operational contexts to clarify and fully coordinate its operationally focused lens. Finally, the JOF was reviewed by the SG including via a series of consultations in early 2023 to consolidate the current framework.

In the spirit of the Sustainable Development Goals, WHO and the International Labour Organization (ILO) produce the WHO/ILO Joint Estimates of the Work-related Burden of Disease and Injury (WHO/ILO Joint Estimates). The WHO/ILO Joint Estimates quantify the population exposed to occupational risk fac...tors and amount health loss caused by these exposures. Global, regional and national estimates are produced of the numbers of deaths and disability-adjusted life years that can be attributed to exposure to selected occupational risk factors. Estimates are produced disaggregated by sex and age group.

Practically, planetary health presents a new way to approach and solve problems. For example, there is
alignment at the highest levels with global policy frameworks – primarily the Convention on Biological
Diversity Aichi Biodiversity Targets, the Paris Climate Agreement, and the Sustainable Dev...elopment
Goals – which will require collaboration across sectors to make progress. While this alignment validates
integrated concepts like planetary health, it also highlights the need for these concepts to be much
more actionable, so that they can be easily taken up by government decision makers as a way to
achieve goals.

One of the ongoing challenges with neglected tropical diseases (NTDs) is that the discovery of medicines to treat them has been very slow. Current global programmes for NTDs largely depend on donated medicines, primarily to treat the world’s poorest people ... most of whom live in remote rural or in deprived urban settings.
WHO recently spoke to Mr Robert J. Gyurik, who discovered albendazole in 1972. He took us through the journey that led him to develop the compound.

La enfermedad de Chagas, también llamada tripanosomiasis americana, sigue siendo endémica en 21 países de América Latina. Sin embargo, como consecuencia de las migraciones, la urbanización, la intensificación del turismo, la modificación de las estrategias agrícolas y el cambio climático, l...a enfermedad ha traspasado el marco rural y el ámbito latinoamericano que le dieron identidad durante decenios, y ha logrado instalarse en la periferia de las ciudades del área endémica y en países de América del Norte, Europa, Asia y Oceanía y transformarse en un problema de salud pública global. Teniendo en cuenta que el Chagas afecta a poblaciones en situación de pobreza en las que produce graves consecuencias para la salud y la economía de las personas infectadas, y que los recursos orientados a fomentar el desarrollo de proyectos de investigación, estrategias de control y planes de atención médica a los pacientes detectados son escasos, la Organización Mundial de la Salud (OMS) incorporó esta enfermedad al grupo de enfermedades infecciosas desatendidas (EID) en el año 2005. Se reconoce actualmente la naturaleza multidimensional de la enfermedad de Chagas, cuya caracterización contempla una intrincada trama de aspectos socioculturales, políticos, biológicos, ambientales y sanitarios. Parte sustancial de todo ello radica en el carácter zoonótico de la endemia y la consiguiente imposibilidad de su erradicación. Por ende, resulta muy complicada la construcción de la ruta crítica para enfrentar esta enfermedad, con la aspiración o el objetivo de su eliminación como problema de salud pública. El propósito de esta guía es ofrecer a los Estados Miembros un instrumento que permita actualizar y estandarizar los procesos de evaluación del control, verificación de la interrupción de la transmisión, y validación de la eliminación de la enfermedad de Chagas como problema de salud pública, en consonancia con: a) la Estrategia y plan de acción para la prevención, el control y la atención de la enfermedad de Chagas; b) el Plan de acción para la eliminación de las enfermedades infecciosas desatendidas y las medidas posteriores a la eliminación 2016-2022; c) el Plan de acción sobre entomología y control de vectores 2018-2023; d) guías o procedimientos operativos estandarizados existentes para la verificación o validación de la eliminación de otras enfermedades infecciosas desatendidas (EID) como la oncocercosis, la filariasis linfática y el tracoma, y e) Enfermedades tropicales desatendidas. Prevención, control, eliminación, erradicación.

Background: The human helminth infections include ascariasis, trichuriasis, hookworm infections, schistosomiasis, lymphatic filariasis (LF) and onchocerciasis. It is estimated that almost 2 billion people worldwide are infected with helminths. Whilst the WHO treatment guidelines for helminth infecti...ons are mostly aimed at controlling morbidity, there has been a recent shift with some countries moving towards goals of disease elimination through mass drug administration, especially for LF and onchocerciasis. However, as prevalence is driven lower, treating entire populations may no longer be the most efficient or cost-effective strategy. Instead, it may be beneficial to identify individuals or demographic groups who are persistently infected, often termed as being “predisposed” to infection, and target treatment at them.
Methods: The authors searched Embase, MEDLINE, Global Health, and Web of Science for all English language, humanbased papers investigating predisposition to helminth infections published up to October 31st, 2017. The varying definitions used to describe predisposition, and the statistical tests used to determine its presence, are summarised. Evidence for predisposition is presented, stratified by helminth species, and risk factors for predisposition to infection are identified and discussed.
Results: In total, 43 papers were identified, summarising results from 34 different studies in 23 countries. Consistent evidence of predisposition to infection with certain species of human helminth was identified. Children were regularly found to experience greater predisposition to Ascaris lumbricoides, Schistosoma mansoni and S. haematobium than adults. Females were found to be more predisposed to A. lumbricoides infection than were males. Household clustering of infection was identified for A. lumbricoides, T. trichiura and S. japonicum. Ascaris lumbricoides and T. trichiura also showed evidence of familial predisposition. Whilst strong evidence for predisposition to hookworm infection was identified, findings with regards to which groups were affected were considerably more varied than for other helminth species.
Conclusion: This review has found consistent evidence of predisposition to heavy (and light) infection for certain human helminth species. However, further research is needed to identify reasons for the reported differences between demographic groups. Molecular epidemiological methods associated with whole genome sequencing to determine ‘who infects whom’ may shed more light on the factors generating predisposition.

Since the launch of the Global Programme to Eliminate Lymphatic Filariasis (GPELF) in 2000, more than 910 million people have received preventive chemotherapy for lymphatic filariasis (LF) and many thousands have received care for chronic manifestations of the disease. To achieve this, millions of c...ommunity drug distributors (CDDs), community members and health personnel have worked together each year to ensure that at-risk communities receive preventive chemotherapy through mass drug administration (MDA). The successes of 20 y of partnership with communities is celebrated, including the application of community-directed treatment, the use of CDDs and integration with other platforms to improve community access to healthcare. Important challenges facing the GPELF moving forward towards 2030 relate to global demographic, financing and programmatic changes. New innovations in research and practice present opportunities to encourage further community partnership to achieve the elimination of LF as a public health problem. We stress the critical need for community ownership in the current Covid-19 pandemic, to counter concerns in relaunching MDA programmes for LF.

The Fifty-first World Health Assembly adopted resolution WHA51.11 in 1998, which targets the
global elimination of trachoma as a public health problem by 2020 (1). The strategy recommended
to achieve that goal is encapsulated by the acronym “SAFE”, which represents: Surgery for
individuals wi...th trachomatous trichiasis (TT; the late blinding stage of trachoma); and Antibiotics,
Facial cleanliness and Environmental improvement (2). The A, F and E interventions are delivered to
entire districts in which active (inflammatory) trachoma is common in order to treat ocular infection
with Chlamydia trachomatis, the causative organism of trachoma, and sustainably reduce its
transmission.

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.

Improving the survival chances and quality of life of women, newborns, and children remains an urgent global challenge. Since 2012, substantial progress has been made in reducing maternal and under-5 deaths, and a only handful of countries are on target to meet the SDG targets in 2030. Yet, 5 millio...n children still die each year under the age of 5, and nearly half of those are newborns less than a month old. Worse still, the global maternal mortality ratio is going in the wrong direction.
A Decade of Progress and Action for the Future will examine the tenacity and innovation that helped us make gains, the lessons learned through monitoring, country-led adaptation and leadership, analysis, and reflection, as well as the approaches we must take to reinvigorate the momentum and global commitment to improving maternal and child survival. Increasing coverage, strengthening the quality of care, and enhancing equity will be tantamount to our global progress.
