exposure to fine particulate matter (PM2.5), which leads to cardiovascular and respiratory diseases, as well as cancers. The fact sheet emphasizes that 99% of the global population lived in areas exceeding WHO air quality guidelines in 2019, with low- and middle-income countries bearing the highest burden. To mitigate these health impacts, WHO advocates for policies and investments that promote cleaner transportation, energy-efficient housing, improved waste management, and access to clean household energy.

The article from The Lancet Global Health discusses the "silent epidemic" of chronic obstructive pulmonary disease (COPD) in Africa, emphasizing its status as an under-recognized yet significant health issue. Although COPD is the third leading cause of death globally, it remains largely overlooked i
...
n African countries. The article highlights studies indicating varying prevalence rates of COPD across sub-Saharan Africa, with major risk factors including tobacco smoking and biomass smoke exposure. The findings suggest that COPD in Africa often affects younger age groups (30–40 years), likely due to early exposure to biomass smoke. The author calls for better education and training for healthcare providers and urges policymakers to address COPD through improved surveillance and effective prevention and treatment strategies.

In Latin America and the Caribbean (LAC), one maternal death was registered every hour in 2020. That same year, the trend in the maternal mortality ratio (MMR) for the Region of the Americas regressed alarmingly and unprecedentedly to the levels seen two decades ago. In addition to indicating a wors

ening of health outcomes, these figures also signal a deepening of inequalities, representing thousands of individual, unacceptable tragedies that in most cases could have been preventable. Maternal death is the result of a multifactorial process in which structural elements such as the economic system, environmental conditions, and culture interact. Other factors related to social inequality are also present, such as racism, poverty, gender inequality, and lack of access to the education system. The current situation calls for urgent mobilization of the health systems of LAC countries in order to strengthen efforts to combat maternal mortality, especially in countries that are still far from achieving the SHAA2030 regional target. For this reason, a preventive, health-promoting, life-course-based approach is needed, with models of care centered on women, families, and the community Scientific evidence shows that health systems with a solid foundation in primary health care (PHC) achieve better outcomes, greater equity, and reduced health expenditures. To address this, PAHO proposes a strategy, aimed primarily at women who are in the most vulnerable situation, who are the ones who represent the greatest burden of maternal mortality, to accelerate the reduction of maternal mortality in the Region of the Americas, based on the expansion and strengthening of PHC.

Planning for public health emergencies should ensure that capabilities developed during previous emergencies are maintained, incorporated, and put into practice when a new event of public health concern arises. Investments in pandemic preparedness lead to more rapid detection and a stronger response
...
to public health threats, thereby shielding communities from the debilitating social and economic effects of epidemics and pandemics. The Pan American Health Organization (PAHO) recognizes the efforts of countries in the Region of the Americas to develop and/or strengthen their respiratory pathogen pandemic plans. PAHO supports planning activities with tools and expertise, aligning these efforts with the Preparedness and Resilience for Emerging Threats (PRET) initiative. The PRET initiative is an innovative approach to improving disease pandemic preparedness. It recognizes that the same systems, capacities, knowledge, and tools can be leveraged and applied for groups of pathogens based on their mode of transmission (respiratory, vector-borne, foodborne etc.). The PRET initiative incorporates the latest tools and approaches for shared learning and collective action established during the COVID-19 pandemic and other recent public health emergencies.

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.

l variations in the prevalence of asthma symptoms in children, with up to 13-fold differences between countries. The rising number of hospital admissions for asthma may reflect an increase in asthma severity, poor disease management and/or the effect of poverty. The financial burden of asthma is relatively high within developed countries (those for which data is available) spending 1 to 2% of their healthcare budget on this condition. Established in 1989, the Global Initiative for Asthma (GINA) attempts to raise awareness about the increasing prevalence of asthma, improve management and reduce the burden of asthma worldwide. Despite global efforts, GINA has not achieved its goal, even among developed nations. There are multiple barriers to reducing the global burden of asthma, including limited access to care and/or medications, and lack of prioritization as a public healthcare priority. In addition, the diversity of healthcare systems worldwide and large differences in access to care require that asthma management guidelines be tailored to local needs.

ethodology and facilitating international collaboration. Its specific aims are: 1) to describe the prevalence and severity of asthma, rhinitis and eczema in children living in different centres, and to make comparisons within and between countries; 2) to obtain baseline measures for assessment of future trends in the prevalence and severity of these diseases; and 3) to provide a framework for further aetiological research into genetic, lifestyle, environmental, and medical care factors affecting these diseases. The ISAAC design comprises three phases. Phase 1 uses core questionnaires designed to assess the prevalence and severity of asthma and allergic disease in defined populations. Phase 2 will investigate possible aetiological factors, particularly those suggested by the findings of Phase 1. Phase 3 will be a repetition of Phase 1 to assess trends in prevalence.

Severe and difficult asthma in a low- and middle-income country (LMIC) can relate to lack of availability of basic medications; potentially reversible factors such as poor adherence or comorbidities such as obesity inhibiting a good response to treatment; and (rarely) true severe, therapy-resistant

asthma. However, definitions of severity should encompass not merely doses of prescribed medication, but also underlying risk. The nature of asthmatic airway disease shows geographical variation, and LMIC asthma should not be assumed to be phenotypically the same as that in high-income countries (HICs). The first assessment step is to ensure another diagnosis is not being missed. Largely, political action is needed if children with asthma are to get access to basic medications. If a child is apparently not responding to low dose, simple medications, the next step is not to increase the dose but perform a detailed assessment of what factors (for example co-morbidities such as obesity, or social factors like poor adherence) are inhibiting a treatment response; in most cases, an underlying reason can be found. An assessment of risk of future severe asthma attacks, side-effects of medication and impaired lung development is also important. True severe, therapy-resistant asthma is rare and there are multiple underlying molecular pathologies. In HICs, steroid-resistant eosinophilia would be treated with omalizumab or mepolizumab, but the cost of these is prohibitive in LMICs, the biomarkers of successful therapy are likely only relevant to HICs. In LMICs, a raised blood eosinophil count may be due to parasites, so treating asthma based on the blood eosinophil count may not be appropriate in these settings.

asthma diagnosis and access to essential medicines by asthmatic patients reduces morbidity and mortality rates. Significant progress has been made in the diagnosis and management of asthma in other countries but not in the health care delivery system in Zimbabwe. Therefore, the aim of this study was to develop algorithm for asthma diagnosis and management for Zimbabwe.

of the earning capacity of the individuals and families is an added problem. Various indicators such as disability-adjusted life years and healthy life years have been used to define the economic burden. The data from Asian countries regarding these parameters is scarce, underlining the need for systematic studies in these countries, especially those that are resource poor. The purpose of this review is to highlight the varying prevalence of asthma in Asia and to assess the likely economic burden for the future.

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.

Antimicrobial resistance (AMR) has emerged as a leading cause of death in the African region, surpassing fatalities from malaria, HIV, and TB. In response to this critical threat, the region has adopted the AMR Global Action Plan and the African Union Framework for Antimicrobial Resistance Control 2

020 – 2025, which is tailored to meet the specific needs of African nations through a coordinated approach. While most countries in the region have developed and prioritized National Action Plans (NAPs) to tackle AMR, the overall response remains inadequate given the magnitude of the threat, which endangers human, animal, environmental, aquatic, and plant health.
Africa bears a significant burden of infectious diseases, accounting for approximately 95% of malaria deaths, 70% of people living with HIV, and 25% of TB deaths globally. In 2019, AMR was linked to approximately 55,000 deaths from HIV, 30,000 from malaria, and 255,000 overall. Major drivers of AMR in the region include the overuse and misuse of antimicrobials in human and food systems, migration, suboptimal vaccination rates, and environmental contamination from hospital and pharmaceutical effluents. Additionally, there is a lack of access to quality-assured antimicrobials and diagnostics, compounded by inadequate knowledge about AMR. Unlike high-income countries, where indiscriminate antimicrobial use is the primary factor driving AMR, African countries face additional challenges, including a lack of access to clean and safe water, poor Water, Sanitation, and Hygiene (WASH) programs, inadequate infection prevention measures, and suboptimal vaccinations for preventable diseases. One in three hospitals in the region lacks clean, safe running water, and one in eight people defecate openly due to inadequate sanitation. Investments in WASH, infection prevention, and biosecurity could save approximately 700,000 lives annually.
Addressing AMR in Africa requires a comprehensive, multi-sectoral approach involving the entire society. Sustainable access to antimicrobials, including antibiotics, vaccines, and therapeutics, is crucial, as lack of access leads to more morbidity and mortality than AMR itself. Support for the region should focus on preventing infections, strengthening health and food systems, developing human resources, ensuring sustainable access to diagnostics and therapeutics, and investing in laboratory infrastructure to support surveillance and data generation.

health emergency of international concern (PHEIC). After these declarations, many countries have made efforts to mobilize resources to introduce or expand laboratory testing, surveillance, and response activities. In particular, as the number of suspected cases surges in the Democratic Republic of Congo (DRC), Burundi, and the Central African Republic, and an increasing number of new countries report cases, there is an urgent need to implement testing to strengthen the Mpox response. However, access to appropriate quality assured diagnostics is a challenge. There is limited information on important characteristics, such as available test kits’ performance and ability to detect relevant clades.
To address the challenge of mpox access in the continent, the Africa CDC Diagnostic Advisory Committee (DAC) met in Kigali from 19-23 August 2024 to review the available evidence on molecular tests for Mpox and to shortlist tests that may be useful for Mpox testing in countries. The shortlist aims to provide guidance to Africa CDC, countries and partners on appropriate high-quality molecular tests to procure and use for the mpox response.
