Now entering its sixth year, the conflict in Syria continues to take a drastic toll on the lives of the Syrian people and to drive an unprecedented humanitarian and protection crisis: some 13.5 million people are now in need of humanitarian assistance and protection, including 6 million children. Ha...lf of the country’s pre-crisis population has been forced from their homes, with around one third of the remaining population now displaced within Syria and over 4.8 seeking refuge in neighbouring countries and beyond.

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.

eLife 2020;9:e52072. The Triatominae are vectors for Trypanosoma cruzi, the aetiological agent of the neglected tropical Chagas disease. Their distribution stretches across Latin America, with some species occurring outside of the Americas. In particular, the cosmopolitan vector, Triatoma rubrofasci...ata, has already been detected in many Asian and African countries. We applied an ensemble forecasting niche modelling approach to project the climatic suitability of 11 triatomine species under current climate conditions on a global scale. Our results revealed potential hotspots of triatomine species diversity in tropical and subtropical regions between 21 ̊N and 24 ̊S latitude. We also determined the climatic suitability of two temperate species (T. infestans, T. sordida) in Europe, western Australia and New Zealand. Triatoma rubrofasciata has been projected to find climatically suitable conditions in large parts of coastal areas throughout Latin America, Africa and Southeast Asia, emphasising the importance of an international vector surveillance program in these regions.

Solidarity” is an international clinical trial to help find an effective treatment for COVID-19, launched by the World Health Organization and partners.
The Solidarity Trial will compare four treatment options against standard of care, to assess their relative effectiveness against COVID-19. By... enrolling patients in multiple countries, the Solidarity Trial aims to rapidly discover whether any of the drugs slow disease progression or improve survival. Other drugs can be added based on emerging evidence.
Until there is sufficient evidence, WHO cautions against physicians and medical associations recommending or administering these unproven treatments to patients with COVID-19 or people self-medicating with them. WHO is concerned by reports of individuals self-medicating with chloroquine and causing themselves serious harm.

This document lays out economic arguments for investing in the Access to COVID-19 Tools Accelerator (ACT-Accelerator). Framed within an overall context that recognizes the broader human health and societal impacts of the COVID-19 crisis, ACT-Accelerator's Economic Investment Case argues that investm...ent in ACT-Accelerator is the world’s best bet and most viable solution for restarting the global economy. It is intended for governments, multilaterals, civil society, businesses and foundations and all those interested in the work required to change the course of the pandemic. The global deployment of ACT-Accelerator’s comprehensive package of tools will reduce the severity of COVID-19 disease, enabling countries to transition out of the crisis thereby restarting domestic and international economic engines driving our global economy.

The World Health Organization's fact sheet on hypertension provides a comprehensive overview of high blood pressure, highlighting its prevalence, risk factors, and health implications. It emphasizes that hypertension is a major cause of premature death worldwide, with an estimated 1.28 billion adult...s aged 30–79 years affected, two-thirds of whom live in low- and middle-income countries.
The document outlines modifiable risk factors, including unhealthy diets, physical inactivity, tobacco and alcohol use, and being overweight or obese. It also discusses non-modifiable risk factors such as family history, age over 65 years, and co-existing conditions like diabetes or kidney disease. The fact sheet underscores the importance of regular blood pressure monitoring, as hypertension often presents without symptoms, and highlights lifestyle changes and medications as effective treatments. Additionally, it mentions global targets aimed at reducing the prevalence of hypertension by 33% between 2010 and 2030.

Climate change and health vulnerability and adaptation assessment
In 2013 the World Health Organization (WHO) published the report Protecting health from climate change:
vulnerability and adaptation assessment. The aim was to provide basic and flexible guidance on conducting national or subnati...onal assessments of current and future vulnerability (the susceptibility of a population or region to harm) to the health risks of climate change, and of policies and programmes that could increase resilience, taking into account the multiple determinants of climate-sensitive health outcomes.
That guidance has been a very useful tool, applied to more than 50 countries and settings, and has helped countries to prepare their health contributions to United Nations Framework Convention on Climate Change national adaptation plans.
Since the launch of the guidance, WHO, technical partners such as Health Canada, and countries have learned much in terms of its applicability in different countries, at national and local levels.
At the same time, knowledge on climate change and health has increased.
WHO, the Pan American Health Organization and Health Canada have produced this updated version, which aims to better support countries in their assessments by proposing a simpler tool that incorporates all lessons learned.

The COVID-19 pandemic has had an unprecedented impact on health care systems that, in many instances, worsened the already existing assistance gaps. When it comes to Latin America and Central America, this challenge adds to the consequences mass mobilizations have had in recent years, which have exc...eeded the national capacities to provide prompt assistance and social protection, particularly in the health care field. This pandemic has a direct impact on people on the move since the movement restriction policies and the lockdown and social distancing measures have reduced their ability to insert themselves into economic activities that were already precarious in many cases. Consequently, they have less access to food, housing, medicines and other essential consumer goods, and fewer possibilities of getting to their countries of destinati

The purpose of the WHO Manual for the Public Health Management of Chemical Incidents is to provide a comprehensive overview of the principles and roles of public health in the management of chemical incidents and emergencies. While this information is provided for each phase of the emergency cycle, ...including prevention, planning and preparedness, detection and alert, response and recovery, it is recognized that the management of chemical incidents and emergencies requires a multi-disciplinary and multi-sectoral approach and that the health sector may play an influencing, complementary or a leadership role at various stages of the management process. The target audience includes public health and environmental professionals, as well as any other person involved in the management of chemical incidents.
WHO and all those involved in the development of the publication hope that the publication will have wide application, especially in developing countries and countries with economies in transition, and that in the future the health sector will be better prepared to acknowledge and fulfill its roles and responsibilities in the management of chemical incidents and emergencies, thereby contributing to the prevention and mitigation of their health consequences.
The publication is also available in French: http://apps.who.int/iris/bitstream/handle/10665/246117/9789242598148-fre.pdf?sequence=1 and in Spanish: http://apps.who.int/iris/bitstream/handle/10665/246118/9789243598147-spa.pdf?sequence=1

In response to the first cases of coronavirus disease 2019 (COVID-19) reported on the continent, many African Union Member States implemented large-scale public health and social measures (PHSM) rapidly. These measures were aimed at reducing transmission and the number of new cases being reported, p...rotecting the most vulnerable populations, and allowing time for countries to ramp up critical healthcare and diagnostic services. While these quick actions bought time for Member States, the negative socio-economic impacts are being felt widely, and countries are now exploring how best to ease these measures back while still managing the outbreak.

Antimicrobial resistance (AMR) is a global public health crisis that resulted in 1.14 million deaths in 2021. According to the Institute for Health Metrics and Evaluation estimates, 96 416 of these deaths occurred in the World Health Organization (WHO) Eastern Mediterranean Region. All 22 countr...ies/territories in the Eastern Mediterranean Region are enrolled in the global AMR
surveillance system, and 17 countries/territories reported data in 2024 (for the year 2023). The total number of isolates reported to the system increased sixfold between 2017 and 2022, but the proportion of blood isolates is relatively very low. Most of the data come from public sector laboratories or hospitals, although the private sector has increased its participation in some countries/territories recently. Three pathogens account for three quarters of all the reported pathogens – Escherichia coli
(26%), Klebsiella pneumoniae (23%), and Staphylococcus aureus (22%).
