Asthma is the most common chronic disease in children globally. The Global Asthma Network (GAN) Phase I study aimed to determine if the worldwide burden of asthma symptoms is changing.
This updated cross-sectional study used the same methods as the International study of Asthma and Allergies in Chi...ldhood (ISAAC) Phase III. Asthma symptoms were assessed from centres that completed GAN Phase I and ISAAC Phase I (1993–95), ISAAC Phase III (2001–03), or both. We included individuals from two age groups (children aged 6–7 years and adolescents aged 13–14 years) who self-completed written questionnaires at school. We estimated the 10-year rate of change in prevalence of current wheeze, severe asthma symptoms, ever having asthma, exercise wheeze, and night cough (defined by core questions in the questionnaire) for each centre, and we estimated trends across world regions and income levels using mixed-effects linear regression models with region and country income level as confounders.
Overall, 119 795 participants from 27 centres in 14 countries were included: 74 361 adolescents (response rate 90%) and 45 434 children (response rate 79%). About one in ten individuals of both age groups had wheeze in the preceding year, of whom almost half had severe symptoms. Most centres showed a change in prevalence of 2 SE or more between ISAAC Phase III to GAN Phase I. Over the 27-year period (1993–2020), adolescents showed a significant decrease in percentage point prevalence per decade in severe asthma symptoms (–0·37, 95% CI –0·69 to –0·04) and an increase in ever having asthma (1·25, 0·67 to 1·83) and night cough (4·25, 3·06 to 5·44), which was also found in children (3·21, 1·80 to 4·62). The prevalence of current wheeze decreased in low-income countries (–1·37, –2·47 to –0·27], in children and –1·67, –2·70 to –0·64, in adolescents) and increased in lower-middle-income countries (1·99, 0·33 to 3·66, in children and 1·69, 0·13 to 3·25, in adolescents), but it was stable in upper-middle-income and high-income countries.
Trends in prevalence and severity of asthma symptoms over the past three decades varied by age group, country income, region, and centre. The high worldwide burden of severe asthma symptoms would be mitigated by enabling access to effective therapies for asthma.

WHO has published the first-ever guidance on the clinical management of diphtheria. The only previously available guidance was an operational protocol. The new guidance followed the rigorous process for developing guidance at WHO.
It addresses the use of Diphtheria Antitoxin (DAT) in the treatmen...t of diphtheria. There is a worldwide shortage of DAT and evidence based recommendations on the use of DAT were requested by many Member States.
The guidance also includes new recommendations on antibiotics. In patients with suspected or confirmed diphtheria, WHO recommends using macrolide antibiotics (azithromycin, erythromycin) rather than penicillin antibiotics.
This clinical practice guideline has been rapidly developed recognizing the global increase in diphtheria outbreaks. Outbreaks of diphtheria in Nigeria, Guinea and neighbouring countries in 2023 have highlighted the urgent need for evidence-based clinical practice guidelines for the treatment of diphtheria. Given the sporadic nature of outbreaks, many clinicians in the affected regions have never managed acute diphtheria and its related complications. Diphtheria remains a neglected disease and vaccination is the top priority. At the same time, for patients with diphtheria, access to antibiotics, DAT and supportive care can be lifesaving.

Malaria remains a significant public health concern in the SADC region, accounting for 20% of childhood deaths, as well as prompting numerous outpatient visits and hospitalisations. Around three-quarters of the population, including 35 million children under the age of five and 8.5 million pregnant ...women, are at risk. Transmission patterns vary from high and stable in the north to malaria-free in the south, with low, unstable and seasonal zones in between. Although interventions such as indoor residual spraying (IRS), insecticide-treated nets (ITNs/LLINs), intermittent preventive treatment in pregnancy (IPTp), rapid diagnostic tests (RDTs), and artemisinin-based combination therapies (ACTs) have reduced the malaria burden, challenges persist in terms of funding, human resources, surveillance, and cross-border coordination. Achieving malaria elimination in the SADC region requires harmonised regional standards, strengthened surveillance, and improved access to quality treatment and policy prioritisation.

20 YEARS OF STRATEGIC HIV AND PUBLIC HEALTH DATA . beThe completion of the 6th South African National HIV Prevalence, Incidence and Behaviour Survey (SABSSM) report, coincides with the celebration of 30 years of democracy in South Africa; and marks 20 years of conducting nationally representative ho...usehold-based surveys by the Human Sciences Research Council (HSRC), its collaborators and donors. Since its inception in 2002, the SABSSM series has emerged as one of the HSRC’s leading scientific contributions to the country’s HIV and AIDS response (1), providing essential data to monitor the HIV epidemic, the impact of the HIV program in South Africa, and to inform strategies for epidemic control in the National Strategic Plan for HIV, TB and STIs (NSP), now in its fifth edition. Using scientific evidence from SABSSM and other key sources, the NSP guides the country’s response, under the leadership of the South African AIDS Council (SANAC) and the National Department of Health (NDoH), with focus on equitable access to biomedical interventions, addressing the structural and social behavioural drivers of the epidemic, and targeting populations disproportionately affected by HIV; such as, black Africans, key populations and adolescent girls and young women (AGYW) aged 15–24 years (2).

The document provides a standardized protocol for evaluating the Early Warning Alert and Response Network (EWARN), a surveillance system used during humanitarian emergencies when regular national health surveillance may be disrupted. The purpose of EWARN is to detect outbreaks of communicable diseas...es early and enable rapid public health response. The guidance explains how the system should be assessed in terms of its structure, implementation, effectiveness, and usefulness. It outlines the key steps of evaluation: preparation, system description, data collection, and post-evaluation reporting. The protocol highlights common challenges observed in previous EWARN implementations, such as delays in establishing the system, limited data quality, weak outbreak response, and lack of clear transition plans back to routine surveillance systems. It emphasizes the need to evaluate both weekly disease reporting and alert verification processes, and to review attributes such as simplicity, data quality, timeliness, sensitivity, and stability. The document also provides templates for interviews, data review forms, and laboratory assessment, as well as guidance on conducting remote evaluations when access is limited. The overall goal of the protocol is to ensure that EWARN functions effectively to detect and respond to outbreaks and that practical recommendations are developed to improve the system’s performance and sustainability in emergency settings.

Складні події останніх років в Україні накладають відбиток на всіх нас. Психологи кваліфікують їх як екстремальні, а емоційну відповідь на них називають «травмати...чним стресом». Нічого ненормального в цьому немає, адже це нормальні реакції на ненормальні події (тобто такі, що виходять за рамки звичного людського досвіду). Страждають від травматичного стресу не лише безпосередні учасники подій, а й ті, хто постійно живе в тривозі, напрузі, спостерігаючи за подіями в ЗМІ або переживаючи за близьких, які можуть бути в небезпеці. Це стосується і дітей. Навіть не розуміючи дета- лей того, що відбувається навколо, вони бачать напруженість і страх батьків, чують тривожні висловлювання. Тому, вірогідно, дітям може знадобитися допомога у відновленні рівноваги. Адже саме дорослі — чи не єдине джерело спокою для них. Ми виклали кілька порад, як поводитися в склад- них ситуаціях і навчитися розуміти себе і своїх дітей. Сподіваємося, вони стануть вам у пригоді.

Health systems the world over have embraced the value of community health workers (CHWs) in extending essential services to the community level, improving health equity and progressing toward universal health coverage. Governments now have an opportunity to institutionalize CHW programs and professi...onalize this essential cadre of the health workforce. What will it take to ensure CHW programs, at scale, can achieve their full potential?
Fortunately, policymakers, funders, NGOs, and other partners seeking to design, revamp, or strengthen CHW programs have a suite of tools at their disposal. One of the longest-standing and most rigorously field-tested of these tools is the Community Health Worker Assessment and Improvement Matrix (CHW AIM), an assessment tool which can be used to design, evaluate and strengthen CHW programs.
You can find this assessment tool on this page here. The matrix is also downloaded on MEDBOX, but if you want, you can register for free and get the matrix. After that follow the points underneath.

The ongoing global pandemic of SARS-CoV-2 (Covid-19) poses unique diagnostic and clinical management challenges in regions where seasonal epidemic-prone diseases are endemic. Diseases such as dengue, malaria, seasonal influenza, leptospirosis, chikungunya, scrub typhus and bacterial infections often... present with febrile syndromes that mimic or co-exist with SARS-CoV-2 infection, complicating diagnosis and treatment. This document provides guidelines for preventing, diagnosing and managing such co-infections. A high level of suspicion is essential during the monsoon and post-monsoon seasons, taking into account region-specific disease prevalence. While the WHO's case definition for SARS-CoV-2 is broad and sensitive, the need for parallel testing for co-infections, in accordance with the protocols of the MoHFW, ICMR, NVBDCP and NCDC, is necessitated by overlapping clinical features. Ensuring the availability of reliable rapid diagnostic kits and applying integrated clinical and laboratory approaches are crucial to improving patient outcomes in the context of concurrent infections.

En 2024, le Cap-Vert et l’Égypte ont été certifiés exempts de paludisme, ce qui prouve qu'il est possible d'éliminer la maladie avec une volonté politique et des ressources adaptées. Cependant, en Afrique, où se concentrent 95 % des cas mondiaux et 97 % des décès (en 2023), les progrès ...stagnent et l’objectif d’élimination d’ici 2030 est menacé. Les principaux obstacles sont le déficit de financement, la résistance aux insecticides et aux médicaments, l'expansion du moustique Anopheles stephensi, le changement climatique, les crises humanitaires et la croissance démographique. Pour inverser la tendance, l’Afrique doit accélérer le déploiement de nouveaux outils (moustiquaires de nouvelle génération, vaccins), renforcer la mobilisation des ressources nationales et diversifier les financements. Une feuille de route de l’Union africaine vise à transformer ces engagements en actions concrètes pour éliminer le paludisme et ses conséquences sanitaires et économiques.
