The aim of the present paper is to review capacity building in public health nutrition (PHN), the need for which has been stressed for many years by a range of academics, national and international organisations. Although great strides have been made worldwide in the science of nutrition, there rema...in many problems of undernutrition and increasingly of obesity and related chronic diseases. The main emphasis in capacity building has been on the nutrition and health workforce, but the causes of these health problems are multifactorial and require collaboration across sectors in their solution. This means that PHN capacity building has to go beyond basic nutrition and beyond the immediate health workforce to policy makers in other sectors. The present paper provides examples of capacity building activities by various organisations, including universities, industry and international agencies. Examples of web-based courses are given including an introduction to the e-Nutrition Academy. The scope is international but with a special focus on Africa. In conclusion, there remains a great need for capacity building in PHN but the advent of the internet has revolutionised the possibilities.

A erradicação da varíola humana (mpox em inglês) foi certificada em 1980. A varíola símia (mpox em inglês) é endêmica nos países da África Central e Ocidental desde a sua primeira detecção, em 1958. Trata-se de uma zoonose cujos casos geralmente ocorrem perto de florestas tropicais, ond...e diversos animais são portadores do ortopoxvírus causador da doença. A maioria das infecções em seres humanos pelo vírus da varíola símia em países onde a doença é endêmica é resultado de transmissão primária de animais para humanos. A transmissão de pessoa a pessoa pode ocorrer por meio de contato próximo com secreções respiratórias ou lesões cutâneas de uma pessoa infectada ou com objetos recém-contaminados. A transmissão também pode ocorrer através da placenta da mãe para o feto ou por contato direto durante ou após o parto. Até 21 de maio de 2022, 12 países onde não há varíola símia endêmica, em 2 regiões da Organização Mundial da Saúde (OMS), haviam notificado 92 casos confirmados da doença. Até 26 de agosto de 2022, 96 países sem endemicidade, de todas as 6 regiões da OMS, haviam notificado 45.198 casos confirmados de varíola símia, incluindo 6 óbitos. No mesmo período, os países onde a doença é endêmica notificaram 350 casos confirmados e 6 óbitos. Na Região das Américas, 29 países e territórios notificaram 23.479 (48%) casos confirmados e 3 óbitos. Diversos estudos observacionais sobre as vacinas de primeira geração demonstraram que a eficácia da vacinação contra a varíola humana na prevenção da varíola símia é de aproximadamente 85%. Atualmente, as vacinas originais (de primeira geração) contra a varíola humana não estão mais disponíveis.

Asthma is the most common chronic respiratory disease among school-going adolescents worldwide. However, the burden of severe asthma is highest in Sub-Saharan Africa. This study aimed to explore teachers’ perceptions of asthma care across six African countries. We conducted focus group discussions... (FGDs) using a semi-structured interview guide. Interviews were audio-recorded, transcribed verbatim and analysed thematically. FGDs were conducted in Kumasi(Ghana), Blantyre (Malawi), Lagos (Nigeria), Durban (South Africa), Kampala (Uganda), and Harare (Zimbabwe) between 01 November 2020 and 30 June 2021. We identified two key themes related to asthma care; barriers to asthma care and suggestions to improve the care of adolescents with asthma. Barriers reported by teachers included a lack of knowledge and skills among themselves, adolescents, and caregivers. In addition, some traditional beliefs of teachers on asthma exacerbated challenges with asthma care in schools. Regarding suggestions, most teachers identified a need for all-inclusive asthma training programmes for teachers, adolescents and caregivers, focusing on acute episodes and mitigating triggers. Utilising teachers with personal experiences with asthma to advocate and support these initiatives was suggested. Further suggestions included the need for annual screening to enable early identification of adolescents with asthma and clarify restrictions on teachers administering asthma medications. Teachers across African schools identify multiple barriers to asthma care. Structured school education programs and annual asthma screening are key to addressing some barriers to care.

The article "Asthma in South African adolescents: a time trend and risk factor analysis over two decades" investigates the prevalence and risk factors for asthma in Cape Town adolescents from 2002 to 2017. The study finds that while the overall prevalence of asthma remained similar, the severity of ...the condition increased significantly. Risk factors for asthma and severe cases include smoking, pet exposure, outdoor pollution, and living in informal housing. Despite these trends, underdiagnosis remains a concern, as only one-third of adolescents with current or severe asthma had been formally diagnosed. The article emphasizes the need for better public health strategies to address environmental exposures and improve asthma diagnosis and treatment.

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.

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.

Mpox is a zoonotic disease caused by a double-stranded DNA virus that belongs to the Orthopoxvirus genus of the Poxviridae family. The disease presents with symptoms similar to smallpox but with a lesser severity. It was first discovered in 1958 when two outbreaks of a poxlike disease occurred in co...lonies of monkeys kept for research, hence the name ‘mpox. The first human case of mpox was recorded in 1970 in the Democratic Republic of the Congo (DRC), which has subsequently spread to other central and western African countries. There are two known clades of the virus: clade I and clade II. Clade I, which is most frequently reported from countries in Central Africa, tends to be more severe than clade II. Cameroon is the only country known to harbour both clades.

About one fourth of the world’s population is estimated to have been infected with the tuberculosis (TB) bacilli, and about 5–10% of those infected develop TB disease in their lifetime. The risk for TB disease after infection depends on several factors, the most important being the person’s im...munological status. TB preventive treatment (TPT) given to people at highest risk of progressing from TB infection to disease remains a critical element to achieve the global targets of the End TB Strategy, as reiterated by the second UN High Level Meeting on TB in 2023. Delivering TPT effectively and safely necessitates a programmatic approach to implement a comprehensive package of interventions along a cascade of care: identifying individuals at highest risk, screening for TB and ruling out TB disease, testing for TB infection, and choosing the preventive treatment option that is best suited to an individual, managing adverse events, supporting medication adherence and monitoring programmatic performance.
