Eight years after Super Typhoon Haiyan, the most destructive storm to ever hit the Philippines, Super Typhoon Rai brought similar torrential rains, violent winds, mudslides, floods and storm surges to central parts of the Philippines, leaving a wide path of destruction and debris in its wake. While ...not as powerful as Haiyan in terms of wind strength, evidence shows that Rai damaged houses, infrastructure and livelihoods on a comparable scale or in even greater numbers. Most striking, Rai damaged 1.57 million homes, 500,000 more than Haiyan, across 11 of the Philippines 17 regions, with around 180,000-200,000 people still displaced – either still in evacuation centers or staying with friends, family or other temporary housing.

Refugee law encompasses both customary law, peremptory norms, and international legal instruments.
The only international instruments directly applying to refugees are the 1951 United Nations Convention Relating to the Status of Refugees and the 1967 Protocol Relating to the Status of Refugees. Bot...h the Convention and the Protocol are open to states, but each may be signed separately. 145 states have ratified the Convention, and 146 have ratified the Protocol. This is the key document to refugee protection plus the text of the Protocol, which removed a deadline and geographical restrictions from the Convention.

Carbon dioxide emissions are the primary driver of global climate change. It’s widely recognised that to avoid the worst impacts of climate change, the world needs to urgently reduce emissions. But, how this responsibility is shared between regions, countries, and individuals has been an endless p...oint of contention in international discussions.
This debate arises from the various ways in which emissions are compared: as annual emissions by country; emissions per person; historical contributions; and whether they adjust for traded goods and services. These metrics can tell very different stories.
We teamed up with the YouTube channel, Kurzgesagt, to produce a video which explored these different metrics in detail: ‘Who is responsible for climate change? – Who needs to fix it?’. All of the data and research featured in this video is contained in this article: below we look in detail at the many ways emissions are broken down.

Adolescent girls and young women (AGYW) remain disproportionately affected by HIV in Eastern and Southern Africa (ESA), with 26 per cent of new infections attributed to this population. AGYW face many personal, social and structural barriers to access, uptake and use of traditional HIV prevention me...thods. Oral Pre-exposure Prophylaxis (PrEP) is proven to be highly effective as an additional prevention choice for reducing the risk of HIV acquisition, including for AGYW. Successful uptake and adherence to PrEP is critical in its effectiveness as an HIV prevention method, however, the current demand for PrEP by AGYW is low with suboptimal adherence.
Within the ESA region, there is currently great impetus to address these challenges and scale up PrEP for AGYW. A critical aspect of this is to leverage the learnings and evidence from implementation of how to improve the demand and quality of PrEP programming for this population. Improving the Quality of Pre-Exposure Prophylaxis Implementation for Adolescent Girls and Young Women in Eastern and Southern Africa examines the current efforts in the region to accelerate and scale up evidence-based PrEP delivery platforms. The implementation brief provides current knowledge and builds on WHO guidance to provide key considerations for implementation, including driving demand and improving quality, as well as focus on wider combination prevention and integration agendas.

Un suivi et une évaluation efficaces sont nécessaires pour atteindre l’objectif d’élimination de la filariose lymphatique (FL). Après le traitement médicamenteux de masse (TMM) conformément aux lignes directrices élaborées par l’OMS, des programmes doivent être mis en œuvre afin de d...éterminer si les interventions ont permis de réduire la prévalence de l’infestation à un niveau en deçà duquel sa transmission ne pourra vraisemblablement pas perdurer. L’enquête d’évaluation
de la transmission (TAS) a été conçue de manière à offrir une structure simple et robuste afin de déterminer si la prévalence de la filariose lymphatique chez des enfants de 6–7 ans est inférieure à un seuil préalablement déterminé. Le TAS fournit aux administrateurs de programmes les informations factuelles nécessaires pour décider de l’opportunité d’arrêter le TMM. Le TAS garantit aux pouvoirs publics que les programmes nationaux ont atteint leur objectif d’élimination de la FL.
Ce guide a été conçu pour enseigner aux membres du personnel des programmes nationaux d’élimination de la FL, notamment le personnel de santé aux niveaux régional et de district, les éléments essentiels des programmes nationaux de suivi et d’évaluation pour l’élimination de la FL. Le guide est axé sur la planification et la mise en œuvre du TAS afin de pouvoir décider de l’opportunité
d’interrompre le TMM et de commencer la surveillance post-TMM.

For many years, Community Health Care Workers (CHWs) in Tanzania and Africa in general have played significant role in community health promotion. Their specific roles have been changing from time to time. However, their key roles have over time included giving health education and dissemination of ...health information to communities, invariably moving on to include other services such as offering curative services and conducting community surveys. Deployment of CHWs has mainly been a response to the severe shortage of the human resource for health in most African countries due to brain drain for various reasons that include unattractive terms and conditions of employment. On the other hand the human resources for health (HRH) is a result of positive growing demand for health services, a situation confronted by inadequate supply of trained health personnel from training institutions to meet the demand.

The Mediclinic article on silicosis provides an overview of this occupational lung disease caused by inhaling silica dust. It explains that inhaled silica particles lead to lung scarring and nodule formation, progressively impairing breathing. The article outlines symptoms such as shortness of breat...h, severe cough, fatigue, loss of appetite, chest pains, and fever. Diagnosis involves a medical examination, detailed occupational history, lung function tests, and imaging like chest X-rays or CT scans to detect lung scarring and nodules. While silicosis is irreversible with no specific cure, management focuses on preventing further silica exposure and treating complications. Preventive measures include maintaining high occupational health standards to control silica dust exposure.

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.

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.

When Ebola hit Liberia in 2014, an atmosphere of fear and confusion contributed to the spread of the virus by making people unwilling to come forward for testing and treatment. Oxfam trained and equipped community health volunteers to go door-to-door, giving information and advice, encouraging anyon...e showing symptoms to go for tests, and keeping their family members informed about the progress of their treatment. The approach won the trust of communities and helped to slow the spread of the disease. This case study gives an overview of the programme, including aims, results and a personal story.
