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 gaps 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.

The increasing prevalence of childhood asthma in the developed world is a cause for concern. A so-called Western lifestyle has been the factor most commonly cited to explain this worrying increase in asthma prevalence. Early studies in a limited number of African countries showed a very low rural pr...evalence of childhood asthma, especially where children lived according to a traditional lifestyle. These same studies showed that asthma was not uncommon in urbanized African children. There has been an
increasing tendency over the past 20 years for those in rural communities to move to the large urban centers. This article analyses the urban-rural differences and factors that influence the development of asthma in susceptible children.

Asthma is the most common chronic respiratory disease (CRD) worldwide and is estimated to affect 262 million causing significant mortality and morbidity, and has emerged as an important public health problem in many Latin American (LA) countries over the last 30 or so years. LA is a highly diverse r...egion in terms of geography, climate, wealth, and ethnicity including 20 different countries with 639 million inhabitants, where 40 million are estimated to have asthma. A common feature of LA countries is the high level of social inequalities3 (Figure 1). In LA, asthma prevalence in both children and adults is highly variable and, where high, is among the highest worldwide, particularly in coastal tropical cities.

Chronic Obstructive Pulmonary Disease (COPD) is now one of the top three causes of death worldwide and 90% of these deaths occur in low- and middle-income countries (LMICs).
More than 3 million people died of COPD in 2012 accounting for 6% of all deaths globally. COPD represents an important public... health challenge that is both preventable and treatable. COPD is a major cause of chronic morbidity and mortality throughout the world; many people suffer from this disease for years and die prematurely from it or its complications. Globally, the COPD burden is projected to increase incoming decades because of continued exposure to COPD risk factors and aging of thepopulation.

In 2014, the International Study of Asthma and Allergies in Childhood (ISAAC) reported that the highest prevalence of symptoms of severe asthma was found in the low- and middle-income countries (LMICs), including Nigeria. While exposure to biomass fuel use may be an important risk factor in the deve...lopment of asthma, its association with asthma symptoms severity has not been well-established. The aim of this study is to extend the spectrum of environmental risk factors that may be contributing towards increasing asthma morbidity, especially asthma symptoms severity in rural schoolchildren in Nigeria and to examine possible asthma underdiagnosis among this population.

There has been a global outbreak of mpox since 2022; this outbreak has been caused by the strain of mpox virus called Clade 2 and has affected around 116 countries worldwide. The current surge in cases is being driven by the rapid spread of a different strain – Clade 1b – which is predominantly ...affecting countries across the African region, particularly DRC, Burundi, Kenya, Uganda and Rwanda [1]. The guidance in this document applies to both Clades of mpox. WHO publishes a dashboard of updated cases globally here. Different Clades and Sub-Clades of mpox behave slightly differently to each other; WHO is monitoring for any significant differences between the Clades, including transmission routes. This guidance will be updated as more information becomes available on this issue.

BACKGROUND. Asthma is a heterogeneous condition characterised by chronic inflammation and variable expiratory airflow limitation, as well as airway reversibility. The burden of asthma in children is increasing in low- and middle-income countries and remains under-recognised and poorly managed.
OBJE...CTIVES. To quantify the burden of asthma in the South African (SA) population and identify the risk factors associated with disease severity in the local context.
METHODS. The SA Childhood Asthma Working Group (SACAWG) convened in January 2017 with task groups, each headed by a section leader, constituting the editorial committee on assessment of asthma epidemiology, diagnosis, control, treatments, novel treatments and self-management plans. The epidemiology task group reviewed the available scientific literature and assigned evidence according to the Grades of Recommendation Assessment, Development and Evaluation (GRADE) system.
CONCLUSIONS. Asthma in children remains a common condition, which has shown an increasing prevalence in urban and rural populations of SA. Of concern is that almost half of children in urban communities experience severe asthma symptoms, and many asthmatics lack a formal diagnosis and thus access to treatment. Exposure to tobacco smoke and living in highly polluted areas increase the severity of wheezing in young children.

Asthma is the most common chronic disease in children, imposing a consistent burden on health system. In recent years, prevalence of asthma symptoms became globally increased in children and adolescents, particularly in Low-Middle Income Countries (LMICs). Host (genetics, atopy) and environmental fa...ctors (microbial exposure, exposure to passive smoking and air pollution), seemed to contribute to this trend. The increased prevalence observed in metropolitan areas with respect to rural ones and, overall, in industrialized countries, highlighted the role of air pollution in asthma inception. Asthma accounts for 1.1% of the overall global estimate of “Disability-adjusted life years” (DALYs)/100,000 for all causes. Mortality in children is low and it decreased across Europe over recent years. Children from LMICs particularly suffer a disproportionately higher burden in terms of morbidity and mortality. Global asthma-related costs are high and are usually are classified into direct, indirect and intangible costs. Direct costs account for 50–80% of the total costs. Asthma is one of the main causes of hospitalization which are particularly common in children aged < 5 years with a prevalence that has been increased during the last two decades, mostly in LMICs. Indirect costs are usually higher than in older patients, including both school and work-related losses. Intangible costs are unquantifiable, since they are related to impairment of quality of life, limitation of physical activities and study performance. The implementation of strategies aimed at early detect asthma thus providing access to the proper treatment has been shown to effectively reduce the burden of the disease.

WHO needs US$ 87.4 million over 6 months, from September 2024 to February 2025, to work with countries, partners and other stakeholders to stop and contain the current outbreak of mpox.
In the Region of the Americas, as of 24 February 2023 (16:00 EST), there are a total of 58,578 confirmed cases of mpox (Table 1, Figure 2) were reported from 31 countries and territories, including 76 deaths in: United States of America (34), Brazil (15), Peru (15), Mexico (4), Chile (2), Ecuador (3...), Argentina (2), and Cuba (1), reported from 31 (Table 1, Annex 1, Figure 3). In the last 4 weeks (28 January – 24 February 2023), 607 additional mpox cases were reported from 16 countries and territories, including 9 deaths in Ecuador (1) and United States (8). Eight countries in the Region account for 97% of confirmed cases: United States of America, Brazil, Colombia, Mexico, Peru, Canada, Chile, and Argentina – listed by total number of cases in decrease order (Figure 4). The number of new weekly reported cases in EW 7 compared to EW 6 of 2023 (% variation) decreased by 55%.

Providing quality, stigma-free services is essential to equitable health care for all and achieving global HIV goals and broader Sustainable Development Goals related to health. Every person has the right to the highest attainable standard of physical and mental health. Countries have a legal obliga...tion to develop and implement legislation and policies that guarantee universal access to quality health services and address the root causes of health disparities, including poverty, stigma and discrimination.
The health sector is uniquely placed to lead in addressing inequity, assuring safe personcentred care for everyone and improving social determinants of health by overcoming taboos and discriminatory or stigmatizing behaviours associated with HIV, viral hepatitis and sexually transmitted infections (STIs). Improving health care quality and reducing stigma work together to enhance health outcomes for people living with HIV. Together, they make health care services more accessible, trustworthy and supportive. This encourages early diagnosis, consistent treatment and improved mental well-being. Thus, people living with HIV are more likely to engage with and benefit from health care services, leading to improved overall health.

WHO Director-General Dr Tedros Adhanom Ghebreyesus has determined that the upsurge of mpox in the Democratic Republic of the Congo (DRC) and a growing number of countries in Africa constitutes a public health emergency of international concern (PHEIC) under the International Health Regulations (2005...) (IHR). Dr Tedros’s declaration came on the advice of an IHR Emergency Committee of independent experts who met earlier in the day to review data presented by experts from WHO and affected countries. The Committee informed the Director-General that it considers the upsurge of mpox to be a PHEIC, with potential to spread further across countries in Africa and possibly outside the continent.
