Chagas disease (CD) is caused by the parasite Trypanosoma cruzi, and it is endemic in Central, South America, Mexico and the South of the United States. It is an important cause of early mortality and morbidity, and it is associated with po...verty and stigma. A third of the cases evolve into chronic cardiomyopathy and gastrointestinal disease. This review proposes strategies to address challenges faced by non-endemic countries

The Public Health Burden of Secondhand Exposure to Commercial Tobacco Smoke Secondhand smoke, the combination of smoke from burning commercial tobacco* products and the smoke breathed out by a person who is smoking, is deadly.
Introduction Pharmacovigilance (PV) systems to monitor drug and vaccine safety are often inadequate in sub-Saharan
Africa. In Malawi, a PV enhancement initiative was introduced to address major barriers to PV.
Objective The objective of this initiative was to improve reporting of adverse events (A...Es) by strengthening passive safety
surveillance via PV training and mentoring of local PV stakeholders and healthcare providers (HCPs) at their own healthcare
facilities (HCFs).
Methods An 18-month PV training and mentoring programme was implemented in collaboration with national stakeholders,
and in partnership with the Ministry of Health, GSK and PATH. Two-day training was provided to Expanded Programme on
Immunisation coordinators, identified as responsible for AE reporting, and four National Regulatory Authority representa-
tives. Abridged PV training and mentoring were provided regularly to HCPs. Support was given in upgrading the national
PV system. Key performance indicators included the number of AEs reported, transmission of AE forms, completeness of
reports, serious AEs reported and timeliness of recording into VigiFlow.
Results In 18 months, 443 HCPs at 61 HCFs were trained. The number of reported AEs increased from 22 (January 2000 to
October 2016) to 228 (November 2016 to May 2018), enabling Malawi to become a member of the World Health Organization
Programme for International Drug Monitoring. Most (98%) AE report forms contained mandatory information on reporter,
event, patient and product, but under 1% were transmitted to the national PV office within 48 h.
Conclusion Regular PV training and mentoring of HCPs were effective in enhancing passive safety surveillance in Malawi,
but the transmission of reports to the national PV centre requires further improvement.

Severe Acute Malnutrition (SAM) is one of the greatest child survival challenges in the world today and
reportedly affects more than 16.2 million children each year1. High impact, proven treatment interventions exist
yet sadly approximately only 3.2 million children with SAM have access to treatme...nt each year2. Thus, there
is a need to scale up interventions to improve coverage and access across high burden countries. While efforts
are currently underway to expand services in many countries, obstacles remain.
One critical barrier to expanding SAM treatment services is the acceptance, accessibility and utilisation of
ready-to-use therapeutic food (RUTF). In some countries and contexts, RUTF is still not fully accepted by
community members; while other countries face problems with procurement, storage and supply chain
management which impact on availability and use3. Reports from Ghana and Zambia highlighted that stock-
outs and logistical challenges are often noted as key contributors to high default rates in outpatient treatment
centres4.

Evidence shows that oral pre-exposure prophylaxis (PrEP) reduces the risk of contracting HIV during sexual intercourse by more than 90% when taken daily. It is for this reason the National HIV Prevention Strategy 2015-2020 (2018 Revision) emphasises the role of preexposure prophylaxis (PrEP) in ...reducing new HIV infections in Malawi.
The Ministry of Health has prioritised PrEP use among the populations most at-risk of HIV infection in Malawi: young women ages 10 to 24 years, sero-discordant couples, female sex workers, men who have sex with men, and other priority populations (such as members of the uniformed services, prisoners, and mobile populations).

Mpox continues to affect people around the world. A new framework released today by WHO will guide health authorities, communities and other stakeholders in preventing and controlling mpox outbreaks, eliminating human-to-human transmission of the disease, and reducing spillover of the virus from ani...mals to humans.
Mpox is a viral illness caused by the monkeypox virus (MPXV). It can cause a painful rash, enlarged lymph nodes and fever. Most people fully recover, but some get very sick. The virus transmits from person to person through close, including sexual, contact. It also has animal reservoirs in east, central and west Africa, where spillovers from animals to humans can occasionally occur, sparking further outbreaks.
There are two different clades of the virus: clade I and clade II. Clade I outbreaks are deadlier than clade II outbreaks.
A major emergence of mpox linked to clade II began in 2017, and since 2022, has spread to all regions of the world. Between July 2022 and May 2023, the outbreak was declared a Public Health Emergency of International Concern. While that outbreak has largely subsided, cases and deaths continue to be reported today, illustrating that low-level transmission continues around the world.
Currently, there is also a major outbreak of clade I virus in the Democratic Republic of the Congo (DRC), where cases have been on the rise for decades. Since the beginning of the year, over 6500 cases and 345 deaths have been reported in the DRC. Almost half of these are among children under the age of 15 years.
The Strategic framework for enhancing prevention and control of mpox (2024–2027) provides a roadmap for health authorities, communities, and stakeholders worldwide to control mpox outbreaks in every context, advance mpox research and access to countermeasures, and to minimize zoonotic transmission.

Chronic kidney disease (CKD) is an important contributor to mortality from noncommunicable diseases. No decrease has been seen for CKD mortality contrary to many other important non-communicable diseases (e.g., cardiovascular disease). The prevalence of CKD and kidney failure are increasing all over... the world – and thereby also the need for dialysis. Unfortunately, the prevalence increases most rapidly in lowand middle-income countries. Globally, there are great inequities in access and quality of management of kidney failure. Many low- and middle-income countries cannot meet the increased need for dialysis. If the patients receive dialysis, it might only be for a limited period due to the out-of-pocket expenses. There are global disparities in CKD mortality reflecting the disparities in access to care. Lack of access to dialysis is an important cause of the increased CKD mortality in low- and middle-income countries.

The article is a scoping review that explores the challenges in diagnosing asthma in children in three sub-Saharan African countries: Nigeria, South Africa, and Uganda. It identifies key barriers, such as a lack of community awareness, inadequate healthcare access, limited diagnostic tools like spir...ometry, and insufficient knowledge among healthcare workers. The review also highlights the stigma associated with asthma and the absence of relevant diagnostic guidelines. Solutions proposed include community education, development and adherence to diagnostic guidelines, and strengthening healthcare systems. The study aims to inform policymakers and healthcare providers to improve asthma diagnosis and care for children in these regions.

The article discusses the significant impact of chronic obstructive pulmonary disease (COPD) as a global health issue, with cigarette smoking as the main risk factor. However, in developing countries, the causes of COPD are often multifactorial, involving environmental tobacco smoke, biomass fuel sm...oke, dust, fumes, childhood illnesses, and tuberculosis (TB). Up to half of COPD patients in these regions are non-smokers. The article emphasizes that while smoking is crucial, other risk factors contribute significantly to COPD, particularly in low- and middle-income countries. It highlights the need for targeted research and public health strategies to address these diverse contributors to COPD, especially in Africa.

Little is known about asthma control in the rising number of African children who suffer from this condition. The Achieving Control of Asthma in Children in Africa (ACACIA) study is an observational study collecting evidence about paediatric asthma in urban areas of Ghana, Malawi, Nigeria, South Afr...ica, Uganda and Zimbabwe. The primary objectives are: (1) to identify 3000 children aged between 12 years and 14 years with asthma symptoms; and (2) to assess their asthma control, current treatment, knowledge of and attitudes to asthma and barriers to achieving good control. Secondary objective is to develop interventions addressing identified barriers to good symptom control.
Each centre will undertake screening to identify 500 school children with asthma symptoms using questions from the Global Asthma Network’s questionnaire. Children identified to have asthma symptoms will fill in a digital survey, including: Asthma Control Test, questions on medication usage and adherence, medical care, the Brief-Illness Perception questionnaire and environmental factors. Exhaled nitric oxide testing and prebronchodilator and postbronchodilator spirometry will be performed. A subgroup of children will participate in focus group discussions. Results will be analysed using descriptive statistics and comparative analysis. Informed by these results, we will assess the feasibility of potential interventions, including the adaption of a UK-based theatre performance about asthma attitudes and digital solutions to improve asthma management.

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.

Since the discovery of insulin nearly 100 years ago, advances in diabetes treatments and therapies have transformed the lives of people
with diabetes (PwD), notably reducing the daily burden of its management.
Newer technologies, including those driven by artificial intelligence, have the potentia...l to further improve the quality of life of PwD and help
identify and diagnose people at risk of developing Type 2 diabetes and diabetes-related complications early. However, medical and technological advances alone are not enough to fix the diabetes challenge. It is also critical to acknowledge the complexity and the seriousness of diabetes, its impact on the quality of life and well-being of over 32 million PwD in the EU and the financial burden it represents for health systems and society at large.

Hepatitis B (HBV) infection is a major public health problem and cause of chronic liver disease.
The 2024 HBV guidelines provide updated evidence-informed recommendations on key priority topics. These include expanded and simplified treatment criteria for adults but now also for adolescents; expa...nded eligibility for antiviral prophylaxis for pregnant women to prevent mother-to-child transmission of HBV; improving HBV diagnostics through use of point-of-care HBV DNA viral load and reflex approaches to HBV DNA testing; who to test and how to test for HDV infection; and approaches to promote delivery of high-quality HBV services, including strategies to promote adherence to long-term antiviral therapy and retention in care.
The 2024 guidelines include 11 updated chapters with new recommendations and also update existing chapters without new recommendations, such as those on treatment monitoring and surveillance for liver cancer.

The World Heart Federation (WHF) Roadmap series covers a large range of cardiovascular conditions. These Roadmaps identify potential roadblocks and their solutions to improve the prevention, detection and management of cardiovascular diseases and provide a generic global framework available for loca...l adaptation. A first Roadmap on raised blood pressure was published in 2015. Since then, advances in hypertension have included the publication of new clinical guidelines (AHA/ACC; ESC; ESH/ISH); the launch of the WHO Global HEARTS Initiative in 2016 and the associated Resolve to Save Lives (RTSL) initiative in 2017; the inclusion of single-pill combinations on the WHO Essential
Medicines’ list as well as various advances in technology, in particular telemedicine and mobile health. Given the substantial benefit accrued from effective interventions in the management of hypertension and their potential for scalability in low and middle-income countries (LMICs), the WHF has now revisited and updated the ‘Roadmap for raised BP’ as ‘Roadmap for hypertension’
by incorporating new developments in science and policy. Even though cost-effective lifestyle and medical interventions to prevent and manage hypertension exist, uptake is still low, particularly in resource-poor areas. This Roadmap examined the roadblocks pertaining to both the demand side (demographic and socio-economic factors, knowledge and beliefs, social relations, norms, and
traditions) and the supply side (health systems resources and processes) along the patient pathway to propose a range of possible solutions to overcoming them. Those include the development of population-wide prevention and control programmes; the implementation of opportunistic screening and of out-of-office blood pressure measurements; the strengthening of primary care and a greater focus on task sharing and team-based care; the delivery of people-centred care and stronger patient and carer education; and the facilitation of adherence to treatment. All of the above are dependent upon the availability and effective distribution of good quality, evidencebased, inexpensive BP-lowering agents.
