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 harmful use of alcohol causes approximately 3 million deaths every year and the overall burden of disease and injuries attributable to alcohol consumption remains unacceptably high. The pace of development and implementation of alcohol policies has been uneven in WHO regions, and resources and c...apacities for implementation of the WHO Global strategy to reduce the harmful use of alcohol 10 years after its endorsement do not correspond to the magnitude of the problems. On this basis, the WHO Executive Board in its decision EB146 (14) called for accelerated action to reduce the harmful use of alcohol.

Effective risk communication requires the alignment of complex factors including trust between the communicator and the audience(s), audience involvement, and emotional responses to risk. Risk communication is especially challenging now as new media changes the landscape for both
communicators and... their audiences. Viewed as a discussion of the most important findings for risk communicators and managers, this report delves into research-driven recommendations for effective risk communication practices.

Infectious diseases like COVID-19 can disrupt the environments in which children grow and develop. Disruptions to families, friendships, daily routines and the wider community can have negative consequences for children’s well-being, development and protection. In addition, measures used to preven...t and control the spread of COVID-19 can expose children to protection risks. Home-based, facility-based and zonal-based quarantine and isolation measures can all negatively impact children and their families.
The aim of this brief is to support child protection practitioners to better respond to the child protection risks during a COVID-19 pandemic. Part 1 presents the potential child protection risks COVID-19 can pose to children. Part 2 presents programmatic options in line with the 2019 Minimum Standards for Child Protection in Humanitarian Action (CPMS) and the Guidance Note: Protection of Children During Infectious Disease Outbreaks.

The pharmacological management of asthma has changed considerably in recent decades, as it has come to be understood that it is a complex, heterogeneous disease with different phenotypes and endotypes. It is now clear that the goal of asthma treatment should be to achieve and maintain control of the... disease, as well as to minimize the risks (of exacerbations, disease instability, accelerated loss of lung function, and adverse treatment effects). That requires an approach that is personalized in terms of the pharmacological treatment, patient education, written action plan, training in correct inhaler use, and review of the inhaler technique at each office visit. A panel of 22 pulmonologists was invited to perform a critical review of recent evidence of pharmacological treatment of asthma and to prepare this set of recommendations, a treatment guide tailored to use in Brazil. The topics or questions related to the most significant changes in concepts, and consequently in the management of asthma in clinical practice, were chosen by a panel of experts. To formulate these recommendations, we asked each expert to perform a critical review of a topic or to respond to a question, on the basis of evidence in the literature. In a second phase, three experts discussed and structured all texts submitted by the others. That was followed by a third phase, in which all of the experts reviewed and discussed each recommendation. These recommendations, which are intended for physicians involved in the treatment of asthma, apply to asthma patients of all ages.

As slight hints of recovery begin to surface in West Africa, UNICEF is looking at the impact of Ebola on children and the response and work of the affected communities in the report, Ebola: Getting to zero – for communities, for children for the future. The document traces some of the outbreak’s... history along with the stories of survivors, health care workers and those working to make things better on the ground. The report also helps map out the actions that urgently must continue to help build resiliency and resuscitate basic services and systems decimated by Ebola.

Terminology used to describe the transmission of pathogens through the air varies across scientific disciplines, organizations and the general public. While this has been the case for decades, during the coronavirus disease (COVID-19) pandemic, the terms ‘airborne’, ‘airborne transmission’ a...nd ‘aerosol transmission’ were used in different ways by stakeholders in different scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations.
This global technical consultation report brings together viewpoints from experts spanning a range of disciplines with the key objective of seeking consensus regarding the terminology used to describe the transmission of pathogens through the air that can potentially cause infection in humans.
This consultation aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities. Despite the complex discussions and challenges, significant progress was made during the consultation process, particularly the consensus on a set of descriptors to describe how pathogens are transmitted through the air and the related modes of transmission. WHO recognizes the important areas where consensus was not achieved and will continue to address these areas in follow-up consultations.

The Global Burden of Disease (GBD) study, a collaborative endeavour of the World
Health Organization (WHO), the World Bank and the Harvard School of Public Health,
drew the attention of the international health community to the burden of neurological
disorders and many other chronic conditions. T...his study found that the burden of neurological
disorders was seriously underestimated by traditional epidemiological and health
statistical methods that take into account only mortality rates but not disability rates. The
GBD study showed that over the years the global health impact of neurological disorders
had been underestimated.

The active participation and engagement of health and care workers (HCWs) in health emergency preparedness, readiness and response is crucial to support risk communication, community engagement and infodemic management (RCCE-IM) interventions during emergencies. HCWs hold unique position...s in society – repeatedly being identified among the main influencers of people’s behaviours: they are one of the most trusted sources of health information and advice in communities and role models for the acceptance and uptake of protective measures during health emergencies. On the frontline, HCWs have valuable insights and knowledge that can be harnessed to support health emergencies across the entire emergency cycle. Between October and December 2023, the WHO Regional Office for Europe interviewed key informants on strategies and experiences to meaningfully engage HCWs during emergencies
