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 number of new Ebola infections in Sierra Leone is declining, despite the outbreak continuing to claim lives. New cases have dropped to around 9-12 per week, according to recent WHO figures. There were over 500 cases per week at the height of the crisis around late November 2014.
The impact on t...he lives of the thousands of people directly affected by the disease has been devastating. It has caused substantial suffering to many others, leaving the population very vulnerable.

As detailed in MSF’s report Confronting the mental health emergency on Samos and Lesbos, the scale of the needs for mental healthcare and the severity of patients’ conditions have overwhelmed the capacity of mental health services on the islands.
The document, "Sustainable Management of Radiotherapy Facilities and Equipment," by WHO and IAEA, provides guidelines for managing radiotherapy equipment and facilities to ensure effective and safe cancer treatment. It covers essential aspects like preventive and corrective maintenance, funding, inf...rastructure, and staffing requirements for sustainable operation. The document aims to support radiotherapy departments, especially in low-resource settings, by outlining strategies for equipment procurement, maintenance, and replacement, emphasizing safety, quality assurance, and optimal patient care.

Building on the 2021 Interim guidance, this second version and update, incorporates the lessons and feedback from the hepatitis pilots that successfully demonstrated the feasibility of measuring hepatitis B and C impact targets to demonstrate elimination, whilst highlighting challenges caused by hig...h disease burden in some countries, as well as delays in reaching mortality targets due to the long natural history of disease progression to liver cirrhosis and hepatocellular carcinoma.
The path to elimination provides a framework with 3 levels of achievements for which WHO certification is available. Each stepwise progression from bronze to silver to gold tiers will promote an iterative expansion of prevention, diagnosis and treatment services for viral hepatitis services and strengthen measurement systems to support attainment of the 2030 elimination goals.
This updated version also includes changes, clarifications and new guidance on alternative measurement approaches for country validation of elimination. Through the validation process, WHO and partners continue to provide country support for strengthening health system capacity and patient-centred services that respect and protect the human rights of people living with viral hepatitis and ensures meaningful engagement of communities in the national, regional and global viral hepatitis response.

The framework responds to the demand from Member States and partners for guidance on how the health sector and its operational basis in health systems can systematically and effectively address the challenges increasingly presented by climate variability and change. This framework has been designed ...in light of the increasing evidence of climate change and its associated health risks (1); global, regional and national policy mandates to protect population health (2); and a rapidly emerging body of practical experience in building health resilience to climate change (3).

2nd edition. The purpose of the WHO human health risk assessment toolkit: chemical hazards is to provide its users with guidance to identify, acquire and use the information needed to assess chemical hazards, exposures and the corresponding health risks in their given health risk assessment contexts... at local and/or national levels.
The Toolkit provides road maps for conducting a human health risk assessment, identifies information that must be gathered to complete an assessment and provides electronic links to international resources from which the user can obtain information and methods essential for conducting the human health risk assessment

Vaccines are powerful weapons in the fight against pandemic viruses as shown by responses to both the 2009 H1N1 influenza and the COVID-19 pandemics. However, planning for accessing, allocating and deploying vaccines in a pandemic situation is a complex endeavour, beset with multiple challenges at a...ll levels – local, regional and global. The World Health Organization (WHO) and its partners have prepared this revised guidance document to assist countries update their national deployment and vaccination plans (NDVPs) by leveraging global learnings from past pandemic responses, including the recent COVID-19 vaccination effort. The development and testing of a NDVP would not only advance pandemic preparedness efforts but would also have benefits in terms of increasing national capabilities to manage other health emergencies which require emergency vaccination campaigns.
