The article "Barriers and determinants of asthma control in children and adolescents in Africa: a systematic review" analyzes factors contributing to poor asthma control in African youth. Based on studies conducted between 2014 and 2019 in Nigeria, Uganda, and South Africa, the review identifies key... challenges such as limited access to asthma diagnosis, inadequate use of inhaled corticosteroids, and environmental and socio-economic factors. It finds that urban living, older age, and concurrent allergic conditions significantly affect asthma management. The study emphasizes the need for improved diagnostic tools, better access to treatment, and tailored public health interventions to enhance asthma outcomes in African children.

Asthma is a heterogeneous condition characterised by chronic inflammation and variable expiratory airflow limitation, as well as airway reversibility. The diagnosis of asthma in young children is limited by the inability to perform objective lung function testing in this group of patients and the wi...de variety of conditions that can phenotypically present with asthma-like symptoms.
This article provides an evidence-based approach for clinicians to accurately diagnose asthma in young children and to assess the level of control to guide therapeutic decisions.
The South African 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 asthma diagnosis and control task groups reviewed the available scientific literature and assigned evidence according to the Grades of Recommendation Assessment, Development and Evaluation (GRADE) system, providing recommendations based on current evidence.

Mass vaccination campaigns to prevent coronavirus disease 2019 (Covid-19) are occurring in many countries; estimates of vaccine effectiveness are urgently needed
to support decision making. A countrywide mass vaccination campaign with the
use of an inactivated severe acute respiratory syndrome c...oronavirus 2 (SARS-CoV-2)
vaccine (CoronaVac) was conducted in Chile starting on February 2, 2021.

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 emergence and transmission of zoonotic diseases are driven by complex interactions
between health, environmental, and socio-political systems. Human movement is considered
a significant and increasing factor in these processes, yet forced migration remains an
understudied area of zoonotic res...earch–due in part to the complexity of conducting interdisciplinary
research in these settings.

This study identifies barriers and provides recommendations to improve asthma care in children across sub-Saharan Africa, where qualitative data is lacking despite high rates.
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.
