Buruli ulcer caused by Mycobacterium ulcerans is a neglected tropical disease characterized by extensive ulceration involving predominantly the upper and lower limbs of patients. The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is lim...ited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

The world faces grave consequences from the lack of available mental health services and treatment. Mental illness impacts every country, culture and community, with the World Health Organization (WHO) stating that 10% of the global burden of disease is related to mental, neurological and substance ...use disorders. In low-and middle-income countries, more than 75% of people with mental disorders receive no treatment at all for their disorder. During 2020, as a result of the global pandemic, 93% of countries reported their mental health services were either halted or interrupted (WHO, 2020e). WHO reported a 25% increase in depression and anxiety alone during the pandemic. The Organisation for Economic Co-operation and Development estimates depression and anxiety cost the global economy US $1 trillion dollars a year. All nurses have a health care role in mental health and substance use. ICN strongly advocates for the investment of further education and professional development in this area in order to support individuals and communities achieve the highest attainable standard of health which includes
physical, mental and social wellbeing.

Dengue creates a staggering epidemiological and economic burden for endemic countries. Without a specific therapy and with a commercial vaccine that presents some problems relative to its full effectiveness, initiatives to improve vector... control strategies, early disease diagnostics and the development of vaccines and antiviral drugs are priorities. In this study, we present the probable origins of dengue in America and the trajectories of its spread. Overall, dengue diagnostics are costly, making the monitoring of dengue epidemiology more difficult and affecting physicians’ therapeutic decisions regarding dengue patients, especially in developing countries. This review also highlights some recent and important findings regarding dengue in Brazil and the Americas. We also summarize the existing DENV polymerase chain reaction (PCR) diagnostic tests to provide an improved reference since these tests are useful and accurate at discriminating DENV from other flaviviruses that co-circulate in the Americas. Additionally, these DENV PCR assays ensure virus serotyping, enabling epidemiologic monitoring.

This brief advocacy document highlights the burden, risks and prevention of injuries and violence, which took the lives of 4.4 million people in 2019 and constitute 8% of all deaths. Among the injury-related causes of death include road traffic crashes, drowning, falls, burns, poisoning and violence... against oneself or others. For people age 5-29 years, three of the top five causes of death are injury-related, including road traffic injuries, homicide, and suicide. Injuries and violence are not evenly distributed across or within countries – some people are more vulnerable than others depending on the conditions in which they are born, grow, work, live and age; in general, being young, male and of low socioeconomic status all increase the risk of injury. This document, aimed at public health professionals; injury prevention researchers, practitioners and advocates; and donors, draws attention to specific strategies based on sound scientific evidence that are effective and cost-effective at preventing injuries and violence; it is critical that these strategies are more widely implemented.

The WHO Global Antimicrobial Resistance and Use Surveillance System (GLASS) was launched in 2015 to foster AMR surveillance and inform strategies to contain AMR. The system started with surveillance of AMR in bacteria causing common human infections and has expanded its scope to include surveillance... of antimicrobial consumption (AMC), invasive fungal infections, and a One Health surveillance model relevant to human health. To meet future challenges, it is in continuous evolution to enhance the quality and representativeness of data to inform the AMR burden accurately. As of the end of 2022, 127 countries, territories and areas participate in GLASS.
The fifth GLASS report, produced in collaboration with Member States, summarizes 2020 data on AMR rates in common bacteria from countries, territories, and areas. The report brings new features, including analyses of population testing coverage or AMR trends. For the first time, the report presents 2020 data on AMC at the national level. A new interactive dashboard allow users to explore AMR and AMC global data, country profiles and download the data.
This report marks the end of the early implementation phase of GLASS. In addition to presenting data collected through the latest data call, this report provides a summary of five years of national AMR surveillance data contributed to GLASS from its initiation, presents AMR findings in the context of progress of country participation in GLASS and in global AMR surveillance coverage and laboratory quality assurance systems at (sub)national level.
Patterns of antimicrobial consumption are presented by country with a particular focus on antibacterials. The report also presents the antimicrobial consumption according to the WHO AWaRe antibiotic classification, for penicillins and cephalosporines. From a One Health perspective, the report presents antimicrobial consumption data in the human sector expressed in tons to allow a comparison with antimicrobial consumption from other sectors (not included in this report).

Atlas of African Health Statistics 2022: Health situation analysis of the WHO African Region
Since 2019, we have been implementing Phase 2 of the regional Transformation Agenda, which informs and aligns with the global WHO Transformation, to ensure WHO is accountable, driven by re- sults and provid...ing value for money in the pursuit of better health. Our global priority in this period is to contribute to delivering on the triple billion targets of expanding universal health coverage, protecting people from emergencies, and promoting health and well-being for people across the Region.
This year’s Atlas of African Health Statistics is being produced in the context of the COVID-19 pandemic that we have been expe- riencing for over two years. The ongoing coronavirus pandemic, together with other health emergencies in the WHO African Re- gion, is yet again testing the strength and resilience of our health systems. Indeed, the impact of COVID-19 is visible in the disruption of services. The report also presents the latest data for more than 50 health-related indicators of the Sustainable Development Goals and WHO’s “triple billion” targets and provides comprehensive country-level statistics using the results chain of the AFRO frame- work of actions for strengthening health systems to achieve UHC and the health-related SDGs.

The Arab region in the Middle East and North Africa (MENA) represents a substantial area of the terrestrial landmass encompassing several countries and ecosystems. This area is generally drier and warmer compared to the rest of the world and has extreme resource limitations that are highly vulnerabl...e to a changing climate, geopolitical instability and land degradation (Slimani & Aidoud, 2004). Agriculture (crops and livestock) is a critical source of employment and a potential option for engaging rural youth. However, environmental degradation coupled with declining and variable agricultural productivity may pose a massive challenge already beset by instability and declining oil reserves (Tagliapietra, 2017). The Arab region is also subjected to short and long-duration climate extreme events, and the overall impact of their cascading effects on ecosystems, societies and economies is still an open question. Climate change, along with post-war geopolitical complexities, has greatly affected the Arab region in terms of its economy and social balance. Climate change has penetrating effects on the region’s agriculture sector and hence its economy. These are mainly manifested via changes in water resources and extreme weather conditions such as heatwaves and a drastic decline in precipitation.

Trachoma causes more vision loss and blindness than any other infection in the world. This disease is caused by Chlamydia trachomatis bacteria. Other variants or strains of these bacteria can cause a sexually transmitted infection (chlamydia) and disease in lymph nodes.
This is photomicrograph ...of a conjunctival smear that revealed the presence of what are known as, intracytoplasmic inclusions Trachoma is easily spread through direct personal contact such as from fingers, through shared towels and clothes, and through flies that have been in contact with the eyes or nose of an infected person. When left untreated, repeated Chlamydia trachomatis infections in the eye can cause severe scarring on the inside of the eyelid. This can cause the eyelashes to scratch the cornea (trichiasis). In addition to causing pain, trichiasis permanently damages the cornea and can lead to irreversible blindness.
Chlamydia trachomatis infections spread in areas that lack access to safely managed drinking water and sanitation systems. Trachoma affects the most resource-limited communities in the world. Globally, almost 1.9 million people have vision loss because of trachoma, and it causes 1.4% of all blindness worldwide.1 In 2021, 136 million people lived in trachoma-endemic areas and were at risk of trachoma blindness.

This strategy defines the World Health Organization (WHO) vision and framework for supporting Member States to accelerate the development, implementation and monitoring of their National Action Plan for Health Security (NAPHS) from 2022 to 2026. The National Action Plan for Health Security (NAPHS) ...are critical to ensure national capacities in health emergency prevention, preparedness, response and recovery are planned, built, strengthened and sustained in order to achieve national, regional and global health security and therefore keep the world safe, serve the vulnerable and promote health.
The strategy promotes, where existing, the use of existing national action plans for health security and not necessary the creation of an additional unique plan. This will avoid duplication and ensure maximum efficiency in domestic resourcing and operationalization efficiency while harnessing external buy-in to support national health priorities.

Population movements have turned Chagas disease (CD) into a global public health problem. Despite the successful implementation of subregional initiatives to control vectorial and transfusional Trypanosoma cruzi transmission in Latin American settings where t...he disease is endemic, congenital CD (cCD) remains a significant challenge. In countries where the disease is not endemic, vertical transmission plays a key role in CD expansion and is the main focus of its control. Although several health organizations provide general protocols for cCD control, its management in each geopolitical region depends on local authorities, which has resulted in a multitude of approaches. The aims of this review are to (i) describe the current global situation in CD management, with emphasis on congenital infection, and (ii) summarize the spectrum of available strategies, both official and unofficial, for cCD prevention and control in countries of endemicity and nonendemicity. From an economic point of view, the early detection and treatment of cCD are cost-effective. However, in countries where the disease is not endemic, national health policies for cCD control are nonexistent, and official regional protocols are scarce and restricted to Europe. Countries of endemicity have more protocols in place, but the implementation of diagnostic methods is hampered by economic constraints. Moreover, most protocols in both countries where the disease is endemic and those where it is not endemic have yet to incorporate recently developed technologies. The wide methodological diversity in cCD diagnostic algorithms reflects the lack of a consensus. This review may represent a first step toward the development of a common strategy, which will require the collaboration of health organizations, governments, and experts in the field.

In 2005, the World Health Organization (WHO) recognized Chagas disease (CD; Trypanosoma cruzi infection) as a neglected tropical disease (NTD) [1] and included it into the global plan to combat NTDs [2]. The Target 3.3 of the United Nations Sustainable Development Goals (UN/SDG) aims at ending the e...pidemics of NTDs by 2030 [3]. Mother-to-child (congenital/connatal) transmission is currently the main mode of transmission of T. cruzi over blood transfusions and organ transplantations in vector-free areas within and outside Latin America (LA). Based on recent demonstrations that congenital transmission can be prevented [4–7], WHO has shifted its objective, in 2018, from control to elimination of congenital CD (cCD).
