Background
Asthma remains highly prevalent, with more severe symptoms in low-income to middle-income countries (LMICs) compared with high-income countries. Identifying risk factors for severe asthma symptoms can assist with improving outcomes. We aimed to determine the prevalence, severity and ris...k factors for asthma in adolescents in an LMIC.
Methods
A cross-sectional survey using the Global Asthma Network written and video questionnaires was conducted in adolescents aged 13 and 14 from randomly selected schools in Durban, South Africa, between May 2019 and June 2021.
Results
A total of 3957 adolescents (51.9% female) were included. The prevalence of lifetime, current and severe asthma was 24.6%, 13.7% and 9.1%, respectively. Of those with current and severe asthma symptoms; 38.9% (n=211/543) and 40.7% (n=147/361) had doctor-diagnosed asthma; of these, 72.0% (n=152/211) and 70.7% (n=104/147), respectively, reported using inhaled medication in the last 12 months. Short-acting beta agonists (80.4%) were more commonly used than inhaled corticosteroids (13.7%). Severe asthma was associated with: fee-paying school quintile (adjusted OR (CI)): 1.78 (1.27 to 2.48), overweight (1.60 (1.15 to 2.22)), exposure to traffic pollution (1.42 (1.11 to 1.82)), tobacco smoking (2.06 (1.15 to 3.68)), rhinoconjunctivitis (3.62 (2.80 to 4.67)) and eczema (2.24 (1.59 to 3.14)), all p<0.01.
Conclusion
Asthma prevalence in this population (13.7%) is higher than the global average (10.4%). Although common, severe asthma symptoms are underdiagnosed and associated with atopy, environmental and lifestyle factors. Equitable access to affordable essential controller inhaled medicines addressing the disproportionate burden of asthma is needed in this setting.

The major neglected tropical diseases, Taenia solium taeniosis/cysticercosis and schistosomiasis caused by Schistosoma mansoni or S. haematobium are presumed to be widely distributed in Africa. Taenia solium taeniosis/ cysticercosis has been reported as an emerging disease in different regions of Af...rica [1, 2], but currently the exact distribution remains unclear. Reported prevalences of T. solium taeniosis and cysticercosis in African countries are not extensive and are further complicated by the lack of ‘gold standard’ tests for diagnosis.

In 2014, GHS/NACP, with support from UNICEF and other partners, conducted a situation analysis on paediatric HIV care and treatment in Ghana. The purpose of this analysis was to identify the gaps within the current delivery of paediatric HIV care and support system and develop a road map for effecti...ve implementation of Early Infant Diagnosis (EID) and to increase paediatric antiretroviral therapy (ART) coverage. The analysis identified gaps such as lack of task shifting on ART services, low paediatric ART coverage, and poor linkage of ART, EID, and PMTCT services with other RCH - immunization and nutrition services.
In view of the findings of the analysis, it was recommended that an Acceleration Plan for Paediatric HIV Services be developed to address the barriers and bottlenecks identified during the assessment. At the current pace of paediatric HIV Services, it can be extrapolated that paediatric ART coverage will increase from 26% to only about 40% by 2020; Ghana will, therefore, fall short of the global target of 90-90-90 (UNAIDS concept).

Climate change is damaging human health now and is projected to have a greater impact in the future. Low- and middle-income countries are seeing the worst effects as they are most vulnerable to climate shifts and least able to adapt given weak health systems and poor infrastructure. Low-carbon appro...ach can provide effective, cheaper care while at the same time being climate smart. Low-carbon healthcare can advance institutional strategies toward low-carbon development and health-strengthening imperatives and inspire other development institutions and investors working in this space. Low-carbon healthcare provides an approach for designing, building, operating, and investing in health systems and facilities that generate minimal amounts of greenhouse gases. It puts health systems on a climate-smart development path, aligning health development and delivery with global climate goals. This approach saves money by reducing energy and resource costs. It can improve the quality of care in a diversity of settings. By prompting ministries of health to tackle climate change mitigation and foster low-carbon healthcare, the development community can help governments strengthen local capacity and support better community health.

Ebola disease and Marburg disease outbreaks continue to occur in Africa, with increased frequency. In addition to resulting in high mortality and morbidity, the outbreaks generate fear and mistrust about the response activities within the communities affected.
Infection prevention and control (IP...C) is a key pillar in the outbreak response; adherence to IPC practices can prevent and control transmission of infections to health and care workers, patients and their family members.
During the 2014-2016 West African Ebola disease outbreak, there was an urgent need for rapid IPC guidance to help support ministries of health, health-care providers and non-governmental organizations (NGOs). In response, WHO produced several documents related to the outbreak based on expert opinion, including IPC-specific documents and documents on clinical management that also referenced key IPC principles and practices. Since that time, many practices in the field have become institutionalized.

Background: Atherosclerotic cardiovascular diseases (ASCVD) including myocardial infarction, stroke and peripheral arterial disease continue to be major causes of premature death, disability and healthcare expenditure globally. Preventing the accumulation of cholesterol-containing atherogenic lipopr...oteins in the vessel wall is central to any healthcare strategy to prevent ASCVD. Advances in current concepts about reducing cumulative exposure to apolipoprotein B (apo B) cholesterol-containing lipoproteins and the emergence of novel therapies provide new opportunities to better prevent ASCVD. The present update of the World Heart Federation Cholesterol Roadmap provides a conceptual framework for the development of national policies and health systems approaches, so that potential roadblocks to cholesterol management and thus ASCVD prevention can be overcome.

To enhance health co-benefits across urban policies which tackle air pollution and climate change, WHO, in cooperation with various international, national, and local partners, implemented the Urban Health Initiative (UHI) pilot project in Accra, Ghana. The Initiative prompted the health sector to u...se its influential position to demonstrate to decision-makers and the public the full range of health, environmental and economic benefits that can be achieved from implementing local emission reduction and energy access policies and strategies. Policy tracking, although not always considered, is a fundamental component of this procedure. It assesses the planning, implementation and progress of a policy to refine or adjust policies with the final objective of increasing the likelihood of the policy being successful. This report is an outcome of the last component of the UHI model process, Policy tracking and monitoring outcomes. The report proposes a framework for tracking urban health policies, with a special focus on the impacts of air quality and energy access on human health and well-being in African countries, giving some examples from the pilot project in Accra. The report also provides resources to survey air quality in cities and other tools to assess public health and the environmental impacts of urban policies and monitor or track their effects.

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 multisector...al 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.

The report “Dementia: a public health priority” has been jointly developed by WHO and Alzheimer's Disease International. The purpose of this report is to raise awareness of dementia as a public health priority, to articulate a public health approach and to advocate for action at international a...nd national levels.
Dementia is a syndrome that affects memory, thinking, behaviour and ability to perform everyday activities. The number of people living with dementia worldwide is currently estimated at 35.6 million. This number will double by 2030 and more than triple by 2050. Dementia is overwhelming not only for the people who have it, but also for their caregivers and families. There is lack of awareness and understanding of dementia in most countries, resulting in stigmatization, barriers to diagnosis and care, and impacting caregivers, families and societies physically, psychologically and economically.
