About six to seven million people worldwide, mostly in Latin America, are estimated to be infected with
Trypanosoma cruzi, the parasite that causes Chagas disease (WHO data from 2021). Chagas disease
...
is
found mainly in endemic areas of 21 Latin American countries. Chagas disease was once entirely
confined to rural areas but in the last decades, due to population movements, most infected people live
in urban settings and the disease has spread to other continents. The burden of disease is due to its
chronic progression with people still suffering years later after initial infection.

h systems to provide adequate management, as well as to implement customized policies and interventions. The PAHO/WHO STEPwise approach to NCD risk factor surveillance (STEPS) is a simple, sequential, standardized method for collecting, analyzing, and disseminating data on key NCD risk factors in countries in adults from 18 to 69 years old. This survey covers key modifiable risk factors: tobacco use, alcohol use, physical inactivity, and unhealthy diet, as well as key biological risk factors: overweight and obesity, raised blood pressure, raised blood glucose, and abnormal blood lipids. STEPS is a household survey that gathers information on the risk factors through a face-to-face interview (step 1), simple physical measurements (step 2), and collection of urine and blood samples for biochemical analysis (step 3). Every step has a core set of questions, measurements, and expanded sets depending on the countries' needs and interests. It also has optional modules. Implementing STEPS allows the comparability of data within and between countries due to its standardized data collection. It also helps health services plan public health priorities and monitors and evaluates population-wide interventions. It is designed to help countries build and strengthen their capacity to conduct surveillance. STEPS captures 11 of the 25 indicators outlined in the NCD Global Monitoring Framework relating to 7 of the nine global targets.

Chagas disease or American trypanosomiasis is, together with geohelminths, the neglected disease that causes more loss of years of healthy life due to disability in Latin America. Chagas
...
disease, as determined by the factors and determinants, shows that different contexts require different actions, preventing new cases or reducing the burden of disease. Control strategies must combine two general courses of action including prevention of transmission to prevent the occurrence of new cases (these measures are cost effective), as well as opportune diagnosis and treatment of infected individuals in order to prevent the clinical evolution of the disease and to allow them to recuperate their health. All actions should be implemented as fully as possible and with an integrated way, to maximise the impact. Chagas disease cannot be eradicated due because of the demonstrated existence of infected wild triatomines
in permanent contact with domestic cycles and it contributes to the occurrence of at least few new cases. However, it is possible to interrupt the transmission of Trypanosoma cruzi in a large territory and to eliminate Chagas disease
as a public health problem with a dramatic reduction of burden of the disease.

Cardiovascular disease (CVD) is the leading cause of global deaths, with the majority occurring in low- and middle-income countries (LMIC). The primary and secondary prevention of CVD is suboptimal throughout the world, but the evidence-practice gap
...
s are much more pronounced in LMIC. Barriers at the patient, health-care provider, and health system level prevent the implementation of optimal primary and secondary prevention. Identification of the particular barriers that exist in resource-constrained settings is necessary to inform effective strategies to reduce the identified evidence-practice gaps. Furthermore, targeting modifiable factors that contribute most significantly to the global burden of CVD, including tobacco use, hypertension, and secondary prevention for CVD will lead to the biggest gains in mortality reduction. We review a select number of novel, resource-efficient strategies to reduce premature mortality from CVD, including: (1) effective measures for tobacco control; (2) implementation of simplified screening and management algorithms for those with or at risk of CVD, (3) increasing the availability and affordability of simplified and cost-effective treatment regimens including combination CVD preventive drug therapy, and (4) simplified delivery of health care through task-sharing (non-physician health workers) and optimizing self-management (treatment supporters). Developing and deploying systems of care that address barriers related to the above, will lead to substantial reductions in CVD and related mortality.

ges that are cost-effective and suited to low-resource settings. Main messages from the volume include:
-Quality matters in all aspects of cancer treatment and palliation.
-Cancer registries that track incidence, mortality, and survival paired with systems to capture causes of death are important to understanding the national cancer burden and the effect of interventions over time.
-Effective interventions exist at a range of prices. Adopting ‘resource appropriate’ measures which allow the most effective treatment for the greatest number of people will be advantageous to countries.
-Prioritizing resources toward early stage and curable cancers is likely to have the greatest health impact in low income settings.
-Research prioritization is no longer just a global responsibility.

Cryptococcal disease is one of the most common opportunistic infections among people living with advanced HIV disease and is a major contributor to severe illness, morbidity, and mortality, particul
...
arly in sub-Saharan Africa.
These guidelines update the recommendations that were first released in 2018 on diagnosing, preventing, and managing cryptococcal disease. In response to important new evidence that became available in 2021, these new guidelines strongly recommend a single high dose of liposomal amphotericin B as part of the preferred induction regimen for the treatment of cryptococcal meningitis in people living with HIV. This simplified regimen - a single high dose of liposomal amphotericin B paired with other standard medicines (flucytosine and fluconazole) - is as effective as the previous WHO standard of care, with the benefits of lower toxicity and fewer monitoring demands.
The objective of these guidelines is to provide updated, evidence-informed recommendations for treating adults, adolescents and children living with HIV who have cryptococcal disease. These guidelines are aimed at HIV programme managers, policymakers, national treatment advisory boards, implementing partners and health-care professionals providing care for people living with HIV in resource-limited settings with a high burden of cryptococcal disease.

Many low-resource settings have a shortage of physicians and health workers.

ich may involve new staff, or the shifting of tasks among existing staff). Teams can include patients themselves, primary care physicians, and other allied health professionals, such as nurses, pharmacists, counsellors, social workers, nutritionists, community health workers, or others. Teams reduce the burden on physicians by utilizing the skills of trained health workers. Strong evidence shows that team-based care is effective in improving hypertension control among patients in a cost-effective way. (2) Some amount of task shifting/team-based care is already taking place in many settings; this module provides further guidance on how to maximize this approach for greater impact.

Background: Cardiovascular disease (CVD), mainly heart attack and stroke, is the
leading cause of premature mortality in low and middle income countries (LMICs).
Identifying and managing individuals at high risk of CVD is an important strategy to
...
prevent and control CVD, in addition to multisectoral population-based interventions to reduce CVD risk factors in the entire population.
Methods: We describe key public health considerations in identifying and managing individuals at high risk of CVD in LMICs.
Results: A main objective of any strategy to identify individuals at high CVD risk is to maximize the number of CVD events averted while minimizing the numbers of
individuals needing treatment. Scores estimating the total risk of CVD (e.g. ten-year risk of fatal and non-fatal CVD) are available for LMICs, and are based on the main CVD risk factors (history of CVD, age, sex, tobacco use, blood pressure, blood cholesterol and diabetes status). Opportunistic screening of CVD risk factors enables identification of persons with high CVD risk, but this strategy can be widely applied in low resource settings only if cost effective interventions are used (e.g. the WHO Package of Essential NCD interventions for primary health care in low resource settings package) and if treatment (generally for years) can be sustained, including continued availability ofaffordable medications and funding mechanisms that allow people to purchase medications without impoverishing them (e.g. universal access to health care). Thisalso emphasises the need to re-orient health systems in LMICs towards chronic diseases management.
Conclusion: The large burden of CVD in LMICs and the fact that persons with high
CVD can be identified and managed along cost-effective interventions mean that
health systems need to be structured in a way that encourages patient registration, opportunistic screening of CVD risk factors, efficient procedures for the management of chronic conditions (e.g. task sharing) and provision of affordable treatment for those with high CVD risk. The focus needs to be in primary care because that is where most of the population can access health care and because CVD programmes can be run effectively at this level.

Many features of the environment have been found to exert an important influence on cardiovascular disease (CVD) risk, progression, and severity. Changes in the environment due to migration to different geographic locations, modifications in lifesty
...
le choices, and shifts in social policies and cultural practices alter CVD risk, even in the absence of genetic changes. Nevertheless, the cumulative impact of the environment on CVD risk has been difficult to assess
and the mechanisms by which some environment factors influence CVD remain obscure. Human environments are complex; and their natural, social and personal domains are highly variable due to diversity in human ecosystems, evolutionary histories, social structures, and individual choices. Accumulating evidence supports the notion that ecological features such as the diurnal cycles of
light and day, sunlight exposure, seasons, and geographic characteristics of the natural environment such altitude, latitude and greenspaces are important determinants of cardiovascular health and CVD risk. In highly developed societies, the influence of the natural environment is moderated by the physical characteristics of the social environments such as the built environment
and pollution, as well as by socioeconomic status and social networks. These attributes of the
social environment shape lifestyle choices that significantly modify CVD risk. An understanding
of how different domains of the environment, individually and collectively, affect CVD risk could
lead to a better appraisal of CVD, and aid in the development of new preventive and therapeutic
strategies to limit the increasingly high global burden of heart disease and stroke.

Methods: The data for this study were collected from surveys, demographic surveillances, medical record reviews, health facility observations and interviews socio-demographic, health care service utilization, and other data sources such as case notifications, scientific literature, and unpublished data as per the Global Burden of Disease protocol and analysis techniques to produce national and regional estimates of maternal hypertensive disorders in Ethiopia. Cause of death ensemble modeling and Bayesian meta-regression disease modeling was employed to ascertain cause of death and morbidity. Each metric was estimated per 100,000 populations with a 95% uncertainty interval (UI).
Results: In the last thirty years, in Ethiopia, , the incidence of maternal hypertensive disorders among young women was raised by 52,596 cases per 100,000 population [199,707 (95% UI 150,261-267,221) to 252,303 (95% UI 191,335-332,524)], while decreased among adolescent women from 67,206 (95% UI 46,887-90,883) to 64, 622 (95% UI; 47,587-84,664) per 100,000 population. The prevalence among women of reproductive age had increased from 94, 818 (95% UI 59,434-135,332) in 1990 to 138, 263 (95% UI 88,447-196,029) in 2019. Between 1990 and 2019, deaths attributable to maternal hypertensive disorders among adolescents and young women had increased by 1.5 and 1.17 times, respectively. In 2019, disability adjusted life years among adolescent, young women and women of reproductive age due to maternal hypertensive disorders was 8,493 (UI 95% 5,370-12,849), 21,812 (UI 95% 14,682-32,139) and 57,867 (UI 95% 41,751-79,165) respectively. The highest daily adjusted life years due to maternal hypertensive disorders had occurred among young women, 13,319 (UI 95% 8,592-19,931) which was higher than 1990 whereas the young women years of life lost had increased.
Conclusions: Based on the finding, increasingly high new cases, prevalence and burden of maternal hypertensive disorders and significant health loss were observed in the last three decades in Ethiopia. Hence, prevention of cases, disabilities, deaths and health losses caused by maternal hypertensive disorders can be prevented by properly advocating lifestyle modifications with specifically designed age-specific interventions. On the top of continuing prevention efforts with newly devised magnesium sulphate administration in the new ANC initiative of the ministry, contextualized, need based, localized, and targeted interventions could be reconstituted.

Furthermore, rates of infections within certain patient populations are significantly higher in limited-resource settings, including surgical patients, patients in intensive-care units (ICU) and neonatal units. It is well documented that environmental contamination plays a role in the transmission of HAIs in healthcare settings. Therefore, environmental cleaning is a fundamental intervention for infection prevention and control (IPC).It is a multifaceted intervention that involves cleaning and disinfection (when indicated) of the environment alongside other key program elements to support successful implementation (e.g., leadership support, training, monitoring, and feedback mechanisms). To be effective, environmental cleaning activities must be implemented within the framework of the facility IPC program, and not as a standalone intervention. It is also essential that IPC programs advocate for and work with facility administration and government officials to budget, operate and maintain adequate water, sanitation and hygiene (WASH) infrastructure to ensure that environmental cleaning can be performed according to best practices.

020 – 2025, which is tailored to meet the specific needs of African nations through a coordinated approach. While most countries in the region have developed and prioritized National Action Plans (NAPs) to tackle AMR, the overall response remains inadequate given the magnitude of the threat, which endangers human, animal, environmental, aquatic, and plant health.
Africa bears a significant burden of infectious diseases, accounting for approximately 95% of malaria deaths, 70% of people living with HIV, and 25% of TB deaths globally. In 2019, AMR was linked to approximately 55,000 deaths from HIV, 30,000 from malaria, and 255,000 overall. Major drivers of AMR in the region include the overuse and misuse of antimicrobials in human and food systems, migration, suboptimal vaccination rates, and environmental contamination from hospital and pharmaceutical effluents. Additionally, there is a lack of access to quality-assured antimicrobials and diagnostics, compounded by inadequate knowledge about AMR. Unlike high-income countries, where indiscriminate antimicrobial use is the primary factor driving AMR, African countries face additional challenges, including a lack of access to clean and safe water, poor Water, Sanitation, and Hygiene (WASH) programs, inadequate infection prevention measures, and suboptimal vaccinations for preventable diseases. One in three hospitals in the region lacks clean, safe running water, and one in eight people defecate openly due to inadequate sanitation. Investments in WASH, infection prevention, and biosecurity could save approximately 700,000 lives annually.
Addressing AMR in Africa requires a comprehensive, multi-sectoral approach involving the entire society. Sustainable access to antimicrobials, including antibiotics, vaccines, and therapeutics, is crucial, as lack of access leads to more morbidity and mortality than AMR itself. Support for the region should focus on preventing infections, strengthening health and food systems, developing human resources, ensuring sustainable access to diagnostics and therapeutics, and investing in laboratory infrastructure to support surveillance and data generation.

There are now improved paediatric friendly TB medicines for treatment of TB in children and health care workers need a reference guide to enable them accurately dispense the TB medicine to children. Malnutrition is a common predisposing factor for TB in children. On the other hand, TB predisposes children to malnutrition or worsens an existing state of malnutrition.

highest risks of dying
from non-communicable diseases (NCDs) worldwide. There is currently
an epidemiological transition on the continent, where NCDs is projected
to outpace communicable diseases within the current decade. Unchecked
increases in CVD risk factors have contributed to the growing burden of three
major CVDs—hypertension, cardiomyopathies, and atherosclerotic diseasesleading to devastating rates of stroke and heart failure. The highest age
standardized disability-adjusted life years (DALYs) due to hypertensive heart
disease (HHD) were recorded in Africa. The contributory causes of heart failure
are changing—whilst HHD and cardiomyopathies still dominate, ischemic
heart disease is rapidly becoming a significant contributor, whilst rheumatic
heart disease (RHD) has shown a gradual decline. In a continent where health
systems are traditionally geared toward addressing communicable diseases,
several gaps exist to adequately meet the growing demand imposed by CVDs.
Among these, high-quality research to inform interventions, underfunded
health systems with high out-of-pocket costs, limited accessibility and
affordability of essential medicines, CVD preventive services, and skill
shortages. Overall, the African continent progress toward a third reduction
in premature mortality come 2030 is lagging behind. More can be done in
the arena of effective policy implementation for risk factor reduction and
CVD prevention, increasing health financing and focusing on strengthening
primary health care services for prevention and treatment of CVDs, whilst
ensuring availability and affordability of quality medicines. Further, investing
in systematic country data collection and research outputs will improve the accuracy of the burden of disease data and inform policy adoption on
interventions. This review summarizes the current CVD burden, important
gaps in cardiovascular medicine in Africa, and further highlights priority
areas where efforts could be intensified in the next decade with potential
to improve the current rate of progress toward achieving a 33% reduction
in CVD mortality.

Cardiac imaging by echocardiography, cardiac computed tomography, cardiac magnetic resonance imaging, single-photon emission computed tomography, and positron emission tomography myocardial perfusion imaging are well-established non-invasive tests that aid in the diagnosis, risk stratification, and management of various cardiac diseases. However, there are significant inequalities in availability and access to imaging modalities in low- and middle-income countries attributed to financial constraints, disparities in healthcare and technical infrastructure. In the post-COVID-19 pandemic era, these disparities are exaggerated by the continued technological advancements driving innovations in the field of cardiovascular (CV) imaging in high-income countries, while there is an urgent need to provide sustainable access to diagnostic imaging for patients in economically strained healthcare systems in regions like Africa. This review aims to highlight the inequalities in the burden of cardiac disease, associated risk factors, and access to diagnostic CV imaging tests, while also exploring the need for sustainable solutions to implementing CV imaging all over the world.

D from a health system perspective and strategies that have been used to promote access, including providing medicines at lower cost, improving medication supply, ensuring medicine quality, promoting appropriate use, and managing intellectual property issues. Using key evidence in published and gray literature and systematic reviews, we summarize advances in access to cardiovascular medicines using the 5 health system dimensions of access: availability, affordability, accessibility, acceptability, and quality of medicines. There are multiple barriers to access of CVD medicines, particularly in low- and middle-income countries. Low availability of CVD medicines has been reported in public and private healthcare facilities. When patients lack insurance and pay out of pocket to purchase medicines, medicines can be unaffordable. Accessibility and acceptability are low for medicines used in secondary prevention; increasing use is positively related to country income. Fixed-dose combinations have shown a positive effect on adherence and intermediate outcome measures such as blood pressure and cholesterol. We have a new opportunity to improve access to CVD medicines by using strategies such as efficient procurement of low-cost, quality-assured generic medicines, development of fixed-dose combination medicines, and promotion of adherence through insurance schemes that waive copayment for long-term medications. Monitoring progress at all levels, institutional, regional, national, and international, is vital to identifying gaps in access and implementing adequate policies.

re at high risk of being infected, STH infection can have a long-term negative impact on their life, including impaired growth and development. Stunting, a form of malnutrition in young children, has been long assumed as one of the risk factors in acquiring the STH infections. However, the studies on STH infection in children under five with stunting have been lacking, resulting in poor identification of the risk. Accordingly, we collected and reviewed existing related research articles to provide an overview of STH infection in a susceptible population of stunted children under five years of age in terms of prevalence and risk factors. There were 17 studies included in this review related to infection with Ascaris lumbricoides, Trichuris trichiura, hookworm, and Strongyloides stercoralis from various countries. The prevalence of STH infection in stunted children ranged from 12.5% to 56.5%. Increased inflammatory markers and intestinal microbiota dysbiosis might have increased the intensity of STH infection in stunted children that caused impairment in the immune system. While the age from 2 to 5 years along with poor hygiene and sanitation has shown to be the most common risk factors of STH infections in stunted children; currently there are no studies that show direct results of stunting as a risk factor for STH infection. While stunting itself may affect the pathogenesis of STH infection, further research on stunting as a risk factor for STH infection is encouraged.

The role of new risk factors such as indoor pollution, infections with human immunodeficiency virus (HIV) and pulmonary tuberculosis (TB), in the pathogenesis of COPD in Africa is increasingly being recognized. This literature review attempts to collect and synthesize information that could be useful in improving COPD care and informing the governments to take appropriate actions for prevention, diagnosis and management of COPD in Africa.

tor Reporting System, we estimate the amounts and patterns of development assistance for global mental health (DAMH) between 2007 and 2013. This allows us to examine how well international donors have responded to calls by global mental health advocates to scale up evidence-based services. Although DAMH did increase between 2007 and 2013, it remains low both in absolute terms and as a proportion of total development assistance for health (DAH). The average annual DAMH between 2007 and 2013 was US$133.57 million, and the proportion of DAH attributed to mental health is less than 1%. Approximately 48% of total DAMH was for humanitarian assistance, education, and civil services. More annual DAMH was channelled into the nonpublic sector than the public sector. Despite an expanding body of evidence suggesting that sustainable mental health care can be effectively integrated into existing health systems at relatively low cost, mental health has not received significant development assistance.

Ahead of World Malaria Day, the WHO Global Malaria Programme published a new operational strategy outlining its priorities and key activities up to 2030 to help change the trajectory of malaria trends, with a view to achieving the global malaria targets. The strategy outlines 4 strategic objectives
...
where WHO will focus its efforts, including developing norms and standards, introducing new tools and innovation, promoting strategic information for impact, and providing technical leadership of the global malaria response.
In recent years, progress towards critical targets of the WHO Global technical strategy for malaria 2016-2030 has stalled, particularly in countries that carry a high burden of the disease. In 2022 there were an estimated 608 000 malaria-related deaths and 249 million new malaria cases globally, with young children in Africa bearing the brunt of the disease.
Millions of people continue to miss out on the services they need to prevent, detect, and treat malaria. Additionally, progress in global malaria control has been hampered by resource constraints, humanitarian crises, climate change and biological threats such as drug and insecticide resistance.
“A shift in the global malaria response is urgently needed across the entire malaria ecosystem to prevent avoidable deaths and achieve the targets of the WHO global malaria strategy,” notes Dr Daniel Ngamije, Director of the Global Malaria Programme. “This shift should seek to address the root causes of the disease and be centred around accessibility, efficiency, sustainability, equity and integration.”

Cardiovascular diseases (CVDs) are a growing public health problem in Ghana and other African countries. Strokes and other CVDs have become a leading cause of death due to increasing risk factors such as hypertension. According to the Global Burden
...
of Disease study (GBD), ischaemic heart disease was the fourth leading cause of death in Ghana in 2016. The prevalence of hyper-
tension, a major risk factor for CVDs, is increasing rapidly and ranges from 19% to 48%, according to the Ghana Health Service Annual Report, 2017, due to rising life expectancy and the increasing prevalence of contributing factors such as overweight/obesity. Early diagnosis and adequate management of the risk factors can reduce the fatal consequences of CVDs.
At the heart of improving risk assessment and management of CVDs are nationally approved guidelines, which facilitate standardisation of care approaches.
These guidelines developed by experts from all levels of health care and stakeholders capture all recommended approaches and necessary information for clinicians and other healthcare workers on CVDs. They also serve as a practical guide for assessing and managing the most important CVDs prevalent in Ghana and can be used at all levels of care namely health facilities without a doctor; with a general practitioner and with a physician specialist.

Non-communicable diseases (NCDs) are the second common cause of death in sub-Saharan Africa (SSA) accounting for about 35% of all deaths, after a composite of communicable, maternal, neonatal, and nutritional diseases.

hat SSA is now at the dawn of the epidemiological transition with contemporary double burden of disease from NCDs and communicable diseases. In SSA, cardiovascular diseases (CVDs) are the most frequent causes of NCDs deaths, responsible for approximately 13% of all deaths and 37% of all NCDs deaths. Although ischemic heart disease (IHD) has been identified as the leading cause of CVDs mortality in SSA followed by stroke and hypertensive heart disease from statistical models, real field data suggest IHD rates are still relatively low. The neglected endemic CVDs of SSA such as endomyocardial fibrosis and rheumatic heart disease as well as congenital heart diseases remain unconquered. While the underlying aetiology of heart failure among adults in high-income countries (HIC) is IHD, in SSA the leading causes are hypertensive heart disease, cardiomyopathy, rheumatic heart disease, and congenital heart diseases. Of concern is the tendency of CVDs to occur at younger ages in SSA populations, approximately two decades earlier compared to HIC. Obstacles hampering primary and secondary prevention of CVDs in SSA include insufficient health care systems and infrastructure, scarcity of cardiac professionals, skewed budget allocation and disproportionate prioritization away from NCDs, high cost of cardiac treatments and interventions coupled with rarity of health insurance systems. This review gives an overview of the descriptive epidemiology of CVDs in SSA, while contrasting with the HIC and highlighting impediments to their management and making recommendations.

ar health community in a unique position to shape the priorities for the next development agenda, and save millions of lives.
Despite its devastating impact on people of all ages, genders and ethnicities, cardiovascular disease was excluded from the Millennium Development Goals (MDGs), which were announced by the United Nations in 2000. That oversight was far-reaching;
for well over a decade, non-communicable diseases were omitted from the global funding agenda and deprioritized by other mechanisms. During that period of muted government action, the prevalence and burden of non-communicable diseases increased in every region of the world.
Fifteen years later, as the successors to the MDGs are being negotiated, we are in a position to call for the prioritization of cardiovascular disease on the forthcoming global development agenda. Once we have ensured that CVD is recognised at the global policy level, our efforts will turn to encouraging governments to honour their commitments on
the prevention and control of CVD.

The Global Burden of Disease Study estimated that asthma caused the loss of 21.6 million healthy years of life (disability-adjusted life years) and 461 069 deaths in 2019. Approximately 90% of the asthma burden of disease is borne by people living low and middle income countries (LMICs). Some countries report very high (up to 90%) rates of uncontrolled asthma. While the prevalence of asthma is highest in countries with a high Socio-Demographic Index (SDI), death rates from asthma are highest in countries with low and lower middle incomes.

chers’ perceptions of asthma care across six African countries. We conducted focus group discussions (FGDs) using a semi-structured interview guide. Interviews were audio-recorded, transcribed verbatim and analysed thematically. FGDs were conducted in Kumasi(Ghana), Blantyre (Malawi), Lagos (Nigeria), Durban (South Africa), Kampala (Uganda), and Harare (Zimbabwe) between 01 November 2020 and 30 June 2021. We identified two key themes related to asthma care; barriers to asthma care and suggestions to improve the care of adolescents with asthma. Barriers reported by teachers included a lack of knowledge and skills among themselves, adolescents, and caregivers. In addition, some traditional beliefs of teachers on asthma exacerbated challenges with asthma care in schools. Regarding suggestions, most teachers identified a need for all-inclusive asthma training programmes for teachers, adolescents and caregivers, focusing on acute episodes and mitigating triggers. Utilising teachers with personal experiences with asthma to advocate and support these initiatives was suggested. Further suggestions included the need for annual screening to enable early identification of adolescents with asthma and clarify restrictions on teachers administering asthma medications. Teachers across African schools identify multiple barriers to asthma care. Structured school education programs and annual asthma screening are key to addressing some barriers to care.

disease is seen in low-income and middle-income countries (LMICs), which have disproportionately high asthma-related mortality relative to asthma prevalence. This is particularly true for many countries in sub-Saharan Africa. Although inhaled asthma treatments (particularly those containing inhaled corticosteroids) markedly reduce asthma morbidity and mortality, a substantial proportion of the children, adolescents, and adults with asthma in LMICs do not get to benefit from these, due to poor availability and affordability. In this review, we consider the reality faced by clinicians managing asthma in the primary and secondary care in sub-Saharan Africa and suggest how we might go about making diagnosis and treatment decisions in a range of resource-constrained scenarios. We also provide recommendations for research and policy, to help bridge the gap between current practice in sub-Saharan Africa and Global Initiative for Asthma (GINA) recommended diagnostic processes and treatment for children, adolescents, and adults with asthma.

Trypanosoma cruzi is the etiological agent of Chagas disease (CD), considered one of the most important parasitic infections in Latin America. Between 25 and 90 million humans are at infection risk via at least one of multiple infection mechanisms.
...
Under natural conditions, the principal transmission modes are transplacental or via one of more than 140 hematophagous triatomine bugs (Reduviidae: Triatominae). Triatomines acquire the parasite from mammal reservoirs due to their obligate blood-feeding (albeit triatomines can also feed on non-reservoir vertebrates such as birds and reptiles). The disease burden for CD in the Latin America and Caribbean region, based on disability-adjusted life-years (DALYs), is at least five times greater than that of malaria, and is approximately one-fifth that of HIV/AIDS. In recent decades, CD has extended to other continents outside natural reservoir or vector distributions due to human migration, with a minimum estimated 10 million individuals infected worldwide.

Using a regression discontinuity design, I find significant but quantitatively small variations in aid to health facilities located within mining areas. Comparing local aid with the additional cost of treatment and prevention associated with the increased risk of malaria transmission, I find suggestive evidence that local populations with the highest burden of the disease receive a proportionately lower share of aid compared to neighbouring areas with reduced exposure to malaria infection. The evidence of disparities in the allocation of aid for malaria supports the view that donors may have inaccurate information about local population needs.

undertreatment persist. There are substantial global variations in the prevalence of asthma symptoms in children, with up to 13-fold differences between countries. The rising number of hospital admissions for asthma may reflect an increase in asthma severity, poor disease management and/or the effect of poverty. The financial burden of asthma is relatively high within developed countries (those for which data is available) spending 1 to 2% of their healthcare budget on this condition. Established in 1989, the Global Initiative for Asthma (GINA) attempts to raise awareness about the increasing prevalence of asthma, improve management and reduce the burden of asthma worldwide. Despite global efforts, GINA has not achieved its goal, even among developed nations. There are multiple barriers to reducing the global burden of asthma, including limited access to care and/or medications, and lack of prioritization as a public healthcare priority. In addition, the diversity of healthcare systems worldwide and large differences in access to care require that asthma management guidelines be tailored to local needs.
