O) Eastern Mediterranean Region (EMR) over the last 2 decades. In 2000, the estimated at-risk population in EMR countries was 12.6 million people, accounting for approximately 1% of the global disease burden. Of the 22 EMR countries, 3 countries (Egypt, Sudan and Yemen) were LF endemic and the disease was suspected in 4 other countries (Djibouti, Oman, Somalia and Saudi Arabia). After almost 2 decades of implementing sustained control and prevention measures, Egypt and Yemen were successfully validated by the WHO as having achieved the elimination criteria in 2017 and 2019, respectively. In 2018, Sudan completed mapping of LF, reaching 26.2% geographical coverage where mass drug administration (MDA) is required and is scaling-up MDA. Extensive epidemiological assessment indicated the absence of LF transmission in the four suspected countries and no MDA required. Challenges faced during the elimination and post-elimination phases are described and discussed

How to Improve Awareness, Treatment, and Control of Hypertension in Africa, and How to Reduce Its Consequences: A Call to Action From the World Hypertension League
Parati, G.; Lackland, G.T.; Campbell, N.R.C. et al.

urden and costs for national health systems. The present call to action aims to stimulate all African countries to adopt several solutions to achieve better hypertension management. The following 3 goals should be achieved in Africa by 2030: (1) 80% of adults with high blood pressure in Africa are diagnosed; (2) 80% of diagnosed hypertensives, that is, 64% of all hypertensives, are treated; and (3) 80% of treated hypertensive patients are controlled. To achieve these aims, we call on individuals and organizations from government, private sector, health care, and civil society in Africa and indeed on all Africans to undertake a few specific high priority actions. The aim is to improve the detection, diagnosis, management, and control of hypertension, now considered to be the leading preventable killer in Africa.

Noncommunicable diseases (NCDs) such as cancer, cardiovascular disease, diabetes and chronic respiratory diseases and their risk factors are an increasing public health and development challenge in Kazakhstan. This report provides evidence through t
...
hree analyses that NCDs reduce economic output and discusses potential options in response, outlining details of their relative returns on investment. An economic burden analysis shows that economic losses from NCDs (direct and indirect costs) comprise 2.3 trillion tenge, equivalent to 4.5% of gross domestic product in 2017. An intervention costing analysis provides an estimate of the funding required to implement a set of policy interventions for prevention and clinical interventions. A cost–benefit analysis compares these implementation costs with the estimated health gains and identifies which policy packages would give the greatest returns on investment. For example, the salt policy package achieved a benefit-to-cost ratio of 118.4 over 15 years, a return of more than 118 tenge for every 1 tenge invested.

nfection, is a silent and neglected cause of morbidity and mortality. However, the burden of disease is likely substantial given the prevalence of chronic viral hepatitis. This burden is further compounded by the lack of screening and access to care and treatment as well as inadequate disease surveillance, human and financial resources.
The National Guidelines for the Management of Viral Hepatitis were developed, with the purpose to:
inform healthcare workers in the public and private sectors about the disease, its epidemiology in South Africa and current methods of diagnosis and therapy
strengthen the healthcare response to viral hepatitis
empower communicable diseases workers and stakeholders to make informed decisions regarding appropriate and cost effective interventions

In January 2021, the World Health Organization (WHO) published a new road map to address the burden of disease and death imposed by neglected tropical diseases (NTDs). The end of the first year of t
...
he 2021-2030 NTD road map is an opportunity to take stock of where we stand and how we plan to move forward.
Considerable progress has been made since 2012 when the first road map was adopted. As of 6 June 2022, forty-six countries have eliminated at least one NTD, while 600 million people no longer require treatment because they are no longer exposed to risks associated with the pathogens that previously harmed them. In some cases, diseases that have plagued humanity for centuries, such as sleeping sickness and Guinea worm disease, are at an all-time low. Less tangible, but also important, there has been significant progress in the way NTDs are viewed. Additionally, the disruptive impact of the COVID-19 pandemic on NTD programmes is evident.
This brochure is the first in a series of advocacy briefs for the new NTD road map presenting highlights of success and challenges towards attaining the 2030 goals.

Background
Low- and middle-income countries now experience the highest prevalence and mortality rates of cardiovascular disease.
Main text
While improving the availability and delivery of proven, effective therapies will no doubt mitigate this
...
burden, we posit that studies evaluating cardiovascular disease risk factors, management strategies and service delivery, in diverse settings and diverse populations, are equally critical to improving outcomes in low- and middle-income countries. Focusing on examples drawn from four cardiovascular diseases — coronary artery disease, stroke, diabetes and kidney disease — we argue that ethnicity, culture and context matter in determining the risk factors for disease as well as the comparative effectiveness of medications and other interventions, particularly diet and lifestyle interventions.
Conclusion
We believe that a host of cohort studies and randomized control trials currently being conducted or planned in low- and middle-income countries, focusing on previously understudied race/ethnic groups, have the potential to increase knowledge about the cause(s) and management of cardiovascular diseases across the world.

Hypertension is the number one health related risk factor in India, with the largest contribution to burden of disease and mortality. It contributes to an estimated 1.6 million deaths, due to ischem
...
ic heart disease and stroke, out of a total of about 10 million deaths annually in India. Fifty seven percent of deaths related to stroke and 24% of deaths related to coronary heart disease are related to hypertension. Hypertension is one of the commonest non-communicable diseases in India, with an overall prevalence of 29.8% among the adult population, and a higher prevalence in urban areas (33.8% vs. 27.6%)
according to recent estimates.
Awareness of hypertension in India is low while appropriate treatment and control among those with hypertension is even lower: Hypertension is a chronic, persistent, largely asymptomatic disease. A majority of the patients with hypertension in India are unaware of their condition. This is because of low levels of awareness and the lack of screening for hypertension in adults-either as a systematic programme or as an opportunistic exercise during visits to healthcare providers.

Mental health in the Americas: an overview of the treatment gap

To understand the mental health treatment gap in the Region of the Americas by examining the prevalence of mental health disorders, use of mental health services, and the global burden of disease.
Antibiotics have been a critical public health tool since the discovery of Penicillin in 1928, saving the lives of millions of people around the world. In developing country like ours, where the burden of treatable
...
disease is very high and access to health facilities and laboratories is difficult, antibiotics have long acted as miracle drugs. Today, however, the emergence of drug
resistance in bacteria is reversing the miracles of the past eighty years, with drug choices for the treatment of many bacterial infections becoming increasingly limited, expensive, and in some cases, nonexistent. Diseases previously regarded as relatively easy to manage are much harder to treat as doctors must use “last-resort” drugs that are more costly, take longer to work
and are often unavailable or unaffordable in developing countries. Moreover, regular prescription of antibiotics, random treatment, over the counter sales, inadequate dosage, inclusion of antibiotics in animal feeds and agriculture has contributed equally to emergence of antibiotics resistance as silent epidemic within the country.

Limited research data on the occurrence of resistant organisms in the nation have, makes it hard to estimate the exact antimicrobial resistance (AMR) scenario. Limited peer reviewed evidence indicates significant divergence from the average resistance trends in APAC region. Nevertheless, several key steps by Government of Myanmar have been instrumental in paving the way for the country to join other nations in the South East Asia Region to speed up its plan on addressing the AMR crisis. Combating antimicrobial resistance would, however, require highest political commitment, multi-sectoral coordination, sustained investment and technical assistance.

e sensitive to climate factors, as well as the local capacity to control the disease. Malaria is also one of the few health outcomes that has been modeled by more than one research group and can therefore facilitate the first model intercomparison for health impacts under a future with climate change. We used bias-corrected temperature and rainfall simulations from the Coupled Model Intercomparison Project Phase 5 climate models to compare the metrics of five statistical and dynamical malaria impact models for three future time periods (2030s, 2050s, and 2080s). We evaluated three malaria outcome metrics at global and regional levels: climate suitability, additional population at risk and additional person-months at risk across the model outputs. The malaria projections were based on five different global climate models, each run under four emission scenarios (Representative Concentration Pathways, RCPs) and a single population projection. We also investigated the modeling uncertainty associated with future projections of populations at risk for malaria owing to climate change. Our findings show an overall global net increase in climate suitability and a net increase in the population at risk, but with large uncertainties. The model outputs indicate a net increase in the annual person-months at risk when comparing from RCP2.6 to RCP8.5 from the 2050s to the 2080s. The malaria outcome metrics were highly sensitive to the choice of malaria impact model, especially over the epidemic fringes of the malaria distribution.

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.

...
orld Health Organization (WHO) regards the disease as a neglected tropical disease, with an estimated 732 million persons being vulnerable to infection worldwide in renowned transmission areas. Steinmann and co-workers documented that over 200 million individuals from Africa, Asia, and South America are infected with this disease. The WHO further estimated that schistosome infections and geohelminths accounts for over 40% of the world tropical disease burden with the exclusion of malaria. Humans get infected with this disease when they make contact with water contaminated with the skin-penetrating cercariae. Prevalence of schistosomiasis, at present, is still high in sub-Saharan Africa. In 2008, 17.5 million people were treated globally for schistosomiasis, 11.7 million of those from sub-Saharan Africa only. Approximately 120 million individuals in sub-Saharan Africa have schistosomiasis-related symptoms while about 20 million undergo hardship as a result of chronic presentations of the disease.

...
disease burden and distributions, risk factors, and control and prevention practices. Dengue continues to disseminate to new areas, including high latitude regions, and a new serotype (dengue virus serotype 5) has been identified. Vaccine research has made new progress, in which the licensed yellow fever and dengue virus quadrivalent chimeric vaccine is now under further safety assessment. In disease surveillance, because of its operational simplicity, rapidity, capability, and utility as an indicator of disease severity, dengue virus NS1 antigen detection has great promotion and application value among primary health care institutions. Vector control progress has driven new breakthroughs in biotechnology, including Wolbachia-infected Aedes and genetically modified Aedes. Both Aedes variants have been used to block transmission of the dengue virus through population replacement and suppression. In the future, vector control should still be pursued as a key measure to prevent transmission, along with anti-viral drug and vaccine research.

It has made good use of existing resources,but has a low health expenditure (of around US$21 per capita, and totalling 4per centof GDP). It has a federal system with devolved healthcare financing, whereby block grants are allocated to sectors at regional and woreda(district) level. The challenge now,with the epidemiological transition (and a sense that the ‘low-hanging fruits’have already been gathered in relation to public health), is how Ethiopia, still poor, continuesto invest in health improvements?Human resources for health (HRH) are a critical pillar within any health system –the health staff combine inputs to provide the services, thus affecting how all other resources are used, and they make frontline (and back-office) decisions thatare importantdeterminants of servicequality,effectiveness and equity. HRH is usually the most resource-intensive element within the health system –commonly absorbing 50–70per centof public expenditure onhealth, although the proportions are very varied by individual countries and across regions. As they are commonly part of the public administration, reforms to HRH are also part of a complex political economy in most countries.Assessing value for money (VfM) in relation to HRH is correspondingly complex;across the value chain, manyfactors influence the conversion of inputs into outputs and outcomes (see Figure 1).A more detailed description of the HRH value chain can be found in Annex1.

y a multifaceted disease, which is distinguished from other arbovirus infections by the intense and debilitating arthralgia that can last for months or years in some individuals. Despite the great social and economic burden caused by CHIKV infection, there is no vaccine or specific antiviral drugs currently available. Recent outbreaks have shown a change in the severity profile of the disease in which atypical and severe manifestation lead to hundreds of deaths, reinforcing the necessity to understand the replication and pathogenesis processes. CHIKF is a complex disease resultant from the infection of a plethora of cell types. Although there are several in vivo models for studying CHIKV infection, none of them reproduces integrally the disease signature observed in humans, which is a challenge for vaccine and drug development. Therefore, understanding the potentials and limitations of the state-of-the-art experimental models is imperative to advance in the field. In this context, the present review outlines the present knowledge on CHIKV epidemiology, replication, pathogenesis, and immunity and also brings a critical perspective on the current in vitro and in vivo state-of-the-art experimental models of CHIKF.

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.

Though there is no unified consensus on the best measures to use for the public’s health and a nation’s epidemiologic situation, it is common for the disease burden to be measured by disease rates (incidence, prevalence, etc.), disease-specific death rates, comparative morbidity and mortality rates, geographic distribution, and disability-adjusted life years (DALYs). The current epidemiological situation, including data on disease rates or geographic distribution for the diseases in Table 1, is discussed below in Section 4. Hotez et al. (2008) were the first to review and compare the burden of DALYs in Latin America and the Caribbean—for NTDs, HIV/AIDS, malaria, and TB—as it existed about 10 years ago. Though the regional burden of TB, malaria, and neglected infectious diseases (NIDs) is somewhat less than it was 10 years ago, work (and schooling) continue to be lost to illness and premature death or disability, and the need for stepping up disease elimination efforts is evident in all communities living in vulnerable conditions....

Strong evidence indicates that the elimination of sleeping sickness ‘as a public health problem’ by 2020 is well within reach. In particular, fewer than one thousand new cases were reported in 2018, and the area where the risk of infection is estimated as moderate, high or very high has shrunk to less than 200,000 km2. More than half of this area is in the Democratic Republic of the Congo. The interruption of transmission of the gambiense form, targeted by the World Health Organization (WHO) for 2030, will require renewed efforts to tackle a range of expected and unexpected challenges. The rhodesiense form of the disease represents a small part of the overall HAT burden. For this form, the problem of under detection is on the rise and, because of an important animal reservoir, the elimination of disease transmission is not envisioned at this stage.

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 report presents the first comprehensive analysis of the magnitude and patterns of socioeconomic, demographic and geographic inequalities in disease burden and access to services for prevention and treatment.
The results confirm there have been improvements in service coverage and decreased disease burden at the national level over the past decade. But they also reveal an uncomfortable reality: unfair inequalities between population subgroups within countries are widespread and have remained largely unchanged over the past decade. For some disease indicators, inequalities are even worsening.
Moreover, the report points to the persistent lack of available data to fully understand inequality patterns in HIV, TB and malaria. Collecting data to improve the monitoring of inequalities in these diseases is vital to develop targeted responses for impact.
There are, encouragingly, isolated successes in reducing inequities. Change is possible when deliberate action is taken to reach disadvantaged populations.

burden of disease. The Knowledge Translation Unit (KTU) of the University of Cape Town Lung Institute has developed, implemented and evaluated a health systems intervention in South Africa, and localised it to Botswana, Nigeria, Ethiopia and Brazil, that simplifies and standardises the care delivered by primary health workers while strengthening the system in which they work. At the core of this intervention, called Practical Approach to Care Kit (PACK), is a clinical decision support tool, the PACK guide. This paper describes the development of the guide over an 18-year period and explains the design features that have addressed what the patient, the clinician and the health system need from clinical guidance, and have made it, in the words of a South African primary care nurse, ‘A tool for every day for every patient’. It describes the lessons learnt during the development process that the KTU now applies to further development, maintenance and in-country localisation of the guide: develop clinical decision support in context first, involve local stakeholders in all stages, leverage others’ evidence databases to remain up to date and ensure content development, updating and localisation articulate with implementation.

Despite recent success, HAT still poses a heavy burden on the rural communities where this highly focal disease occurs, most notably in Central Africa. Since patients are also reported from non-endemic countries outside Africa, HAT should be considered in differential diagnosis for all travellers, tourists, migrants and expatriates who have visited or lived in endemic areas. In the absence of a vaccine, disease control relies on case detection and treatment, and vector control. Available drugs are sub-optimal, but ongoing clinical trials give hope for safer and simpler treatments.

This country cooperation strategy (CCS) outlines how the World Health Organization (WHO) will work with the Lao People’s Democratic Republic over the next five years (2024–2028), supporting the implementation of the five-year health sector development plans and the Health Sector Reform Strategy
...
2021–2030 to attain the Sustainable Development Goals (SDGs) by 2030.
The Lao People’s Democratic Republic experienced substantial economic growth in the 30 years prior to the coronavirus disease (COVID-19) pandemic, contributing to reduced poverty and significant progress toward the SDGs. However, the COVID-19 pandemic brought this development to a halt. It was anticipated that the COVID-19 recovery and the tremendous population growth in recent years would provide opportunities for a shift toward more sustainable and inclusive development in the years ahead. In 2023, however, the contrary was the case. Rural residents, including many ethnic minorities, continued to face marginalization because of limited access to education, health care and economic opportunities.
Despite the challenges of COVID-19 and other disease outbreaks, the country has made significant improvements in health. Nonetheless, progress has been uneven and not everyone has benefited from these achievements. In the mountainous region, many people lack access to quality health care because of the unequal distribution of well-trained health-care workers. Preventable deaths due to poor-quality health care for children and newborns, infants and mothers remain a concern, as do communicable diseases such as sexually transmitted infections and tuberculosis. The increasing burden of noncommunicable diseases and the health impact of worsening climate change further heighten the need for strengthened and resilient health systems, which are at risk due to an underfunded health sector and weak economy.
This CCS aims to address remaining and future challenges as well as health needs while creating an impact that is sustainable. It identifies three strategic priorities and nine deliverables (Table 1) to support the attainment of the national vision of Health for all by all, as articulated in the 9th Health Sector Development Plan 2021–2025. It contributes to the country’s goals to achieve universal health coverage, graduate from least developed country status by 2026 and attain SDGs by 2030.

y countries were frequently carried out in an ad hoc and nonstandardized fashion. In 2013, there were at least 2,200 different districts (of the 4,851 districts in the WHO African region) that still required mapping, and in many of these districts, more than one disease needed to be mapped. During its 3-year duration from January 2014 through the end of 2016, the project carried out mapping surveysfor one ormore NTDs in at least 2,500 districts in 37 African countries. At the end of 2016, most (90%) of the 4,851 districts had completed the WHO-required mapping surveys for the five targeted Preventive Chemotherapy (PC)-NTDs, and the impact of this accelerated WHO/AFRO NTD Mapping Project proved to be much greater than just the detailed mapping results themselves. Indeed, the AFRO Mapping
Project dramatically energized and empowered national NTD programs, attracted donor support for expanding these programs, and developed both a robust NTD mapping database and data portal. By clarifying the prevalence and burden
of NTDs, the project provided not only the metrics and technical framework for guiding and tracking program implementation and success but also the research opportunities for developing improved diagnostic and epidemiologic sampling tools for all 5 PC-NTDs—lymphatic filariasis, onchocerciasis, schistosomiasis, soil-transmitted helminthiasis, and trachoma.

aribbean in respect of the prevalence and incidence of dementia and its impact on the health status of older people. As dementia is a significant global health problem which also has social and economic impacts this document highlights the importance of monitoring dementia in the region. The document evidences that dementia is one of the main contributors to dependence and disability in older people in Latin America and the Caribbean and, although its prevalence and incidence increase exponentially with age, it is not part of normal aging. Alzheimer’s disease is the most common dementia, and there is no cure for this condition, but with timely diagnosis is possible to ameliorate symptoms. It is important to assess what are the needs of people leaving with dementia and their families and to integrate dementia risk reduction strategies in pre-existing strategies for other non-communicable diseases. As shown in the report, despite the huge burden dementia is still underdiagnosed, and it is fundamental to better monitor its prevalence, incidence and the different societal impact that dementia can have. For that, it is crucial to promote the use of harmonized methodologies to address this information in a broader number of studies and countries in the region. This can contribute to the generation of direct actions to decrease dementia risk and lead to healthier lives for people with dementia and their families.

Nations adopted the 2030 Agenda for Sustainable Development. It sets out 17 Goals, which include 169 targets. These wide-ranging and ambitious Goals interconnect. SDG 3 is to ensure healthy lives and promote well-being for all at all ages. It has 13 targets measured through 26 indicators. However, a person’s health and well-being are affected not only by disease and treatment, but also by social and economic factors such as housing, poverty and education. Health targets can therefore also be found across the other SDGs. This fact sheet shows how alcohol consumption undermines commitments to achieve 13 of the 17 SDGs, impacting on a range of health-related indicators, such as child health, infectious diseases and road injuries as well as much broader range of indicators related to economic and social development, environment and equality. The inclusion of a specific target on harmful use of alcohol (SDG 3.5: strengthen the prevention and treatment of substance abuse, including narcotic drug abuse and harmful use of alcohol) into the SDGs demonstrates the key role of alcohol within the global development agenda. The factsheet highlights positive examples of Member States’ experiences. It provides a short overview of the most cost-effective and feasible policy recommendations to reduce alcohol consumption and alcohol-attributable burden in the WHO European Region, in line with the European Action Plan to Reduce the Harmful Use of Alcohol. It also suggests some important resources for Member States. This factsheet was launched as part of the European Awareness Week on Alcohol Related Harm 2020.

respectively, than other reproductive aged adults (15 years old and older). Globally, new infections among these key populations account for 45% of all new HIV infections. This figure is likely to be an underestimate, given the intense stigma associated with disclosing and reporting acquisition risks for HIV among gay men, people who use drugs, sex workers, and transgender people. In addition, HIV epidemics in the majority of low- and middle-income countries (90 of 120) have concentrated epidemics among key populations. In countries with more broadly generalized epidemics, risks are still not evenly distributed and key populations still shoulder disease burden that is markedly disproportionate.

Methods: We leveraged data from IHME’s Development Assistance for Health database, COVID development assistance database and the OECD’s Creditor Reporting System online database. We utilized an updated keyword list to identify the relevant human resources for health-related activities from the project databases. When possible, we also estimated the fraction of human resources for health projects that considered and/or focused on gender as a key factor. We described trends, examined changes in the availability of human resources for health-related development assistance since the adoption of the Global Strategy and compared disease burden and availability of donor resources.

and urban settings, cardiovascular risk factors such as tobacco use, excessive alcohol consumption, unhealthy diet, hypertension, diabetes, hyperlipidemia, overweight, and obesity, are documented to be higher in this review. Increased urbanization, lifestyle changes, lack of awareness and rural to urban movement have been found to increase CVD risk factors in Tanzania. Despite the identification of modifiable risk factors for CVDs, there is still limited information on physical inactivity and eating habits among Tanzanian population that needs to be addressed. Conclusively, primary prevention, improved healthcare system, which include affordable health services, availability of trained health care providers, improved screening and diagnostic equipment, adequate guidelines, and essential drugs for CVDs are the key actions that need to be implemented for cost effective control and management of CVDs. Effective policy for control and management of CVDs should also properly be employed to ensure fruitful implementation of different interventions.
