Malawi is a landlocked country with a surface area of 118,484 km2. Administratively, the country is divided into three regions, namely the Northern, Central and Southern regions. The country has 28 districts, which are further divided into traditional authorities (TA) ruled by chiefs. The TAs are su...b-divided into villages, which form the smallest administrative units. The Village Development Committees (VDCs) under the TAs are responsible for development activities. Politically, each district is divided into constituencies that are represented by Members of Parliament (MPs) in the National Assembly for purposes of legislations. Constituencies are further divided into wards which are represented by a ward councillor at district assembly.

Between epidemiological weeks (EW) 1 and 22 of 2024, a total of 9,541,015 suspected cases of dengue were reported, resulting in a cumulative incidence of 1,011 per 100,000 population. This represents an increase of 230% compared to the same period i...n 2023 and 421% compared to the average of the last 5 years. Figure 1 shows the trend of suspected dengue cases as of EW 22.

The article investigates the global burden and risk factors of chronic obstructive pulmonary disease (COPD). It emphasizes that COPD is a leading cause of morbidity and mortality worldwide, with significant health and economic impacts. The study identifies smoking as the primary risk factor, but als...o highlights other contributors such as occupational exposure, air pollution, and respiratory infections. The authors discuss variations in COPD prevalence and mortality rates across different regions, influenced by socioeconomic and environmental factors. The article calls for comprehensive public health strategies to reduce exposure to risk factors and improve early diagnosis and management to curb the global impact of COPD.

Asthma is the most common chronic disease in children, imposing a consistent burden on health system. In recent years, prevalence of asthma symptoms became globally increased in children and adolescents, particularly in Low-Middle Income Countries (LMICs). Host (genetics, atopy) and environmental fa...ctors (microbial exposure, exposure to passive smoking and air pollution), seemed to contribute to this trend. The increased prevalence observed in metropolitan areas with respect to rural ones and, overall, in industrialized countries, highlighted the role of air pollution in asthma inception. Asthma accounts for 1.1% of the overall global estimate of “Disability-adjusted life years” (DALYs)/100,000 for all causes. Mortality in children is low and it decreased across Europe over recent years. Children from LMICs particularly suffer a disproportionately higher burden in terms of morbidity and mortality. Global asthma-related costs are high and are usually are classified into direct, indirect and intangible costs. Direct costs account for 50–80% of the total costs. Asthma is one of the main causes of hospitalization which are particularly common in children aged < 5 years with a prevalence that has been increased during the last two decades, mostly in LMICs. Indirect costs are usually higher than in older patients, including both school and work-related losses. Intangible costs are unquantifiable, since they are related to impairment of quality of life, limitation of physical activities and study performance. The implementation of strategies aimed at early detect asthma thus providing access to the proper treatment has been shown to effectively reduce the burden of the disease.

Asthma is one of the most common chronic respiratory conditions in the world and is increasing in prevalence, particularly in Africa and other low-income countries. The disproportionately high numbers of premature deaths and severe or uncontrolled cases in many African countries are indicative of th...eir inability to cope with a costly disease like asthma. Progress has, however, been made in understanding the complex and heterogeneous nature of the disease. The objective of this study will be to summarise the epidemiological literature on the nature of asthma in African countries.

Asbestos, the most frequent cause of occupational cancer, continues to be consumed ona massive scale, with millions of people exposed on a daily basis. This review explains why we havefailed in curtailing the silent epidemic of asbestos-related disease and why the numbers of asbestosvictims are like...ly to remain high. Emerging and developed countries have to be reminded that asbestosexposure has yet to become a problem of the past. The worldwide spread of asbestos, followed by thesurge of asbestos-related cancers, resembles the lung cancer epidemic caused by smoking andstimulated by manufacturers.

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 document outlines the 2019 update to the South African guideline for managing chronic obstructive pulmonary disease (COPD). It emphasizes the importance of early diagnosis, prevention through smoking cessation, use of bronchodilators as primary pharmacotherapy, and a comprehensive approach to pa...tient care including pulmonary rehabilitation and the management of comorbidities. The guideline also covers recommendations for handling acute exacerbations, surgical interventions, and long-term treatment options.

Asthma has a significant impact on people of all ages, particularly children. A lack of universally accepted case definition and confirmatory tests and a poor understanding of major risks interfere with a global response. We aimed to provide global estimates of asthma prevalence and cases in 2019 ac...ross four main epidemiological case definitions – current wheezing, ever wheezing, current asthma, and ever asthma. We further investigated major associated factors to determine regional and national distributions of prevalence and cases for current wheezing and ever asthma.

This study aimed to analyze the geographical distribution of coronavirus disease 2019 (COVID-19) and to identify high-risk areas in space and time for the occurrence of cases and deaths in the indigenous population of Brazil. This is an ecological study carried out between 24 March and 26 October 20...20 whose units of analysis were the Special Indigenous Sanitary Districts. The Getis-Ord General G and Getis-Ord Gi* techniques were used to verify the spatial association of the phenomena and a retrospective space–time scan was performed. There were 32 041 confirmed cases of COVID-19 and 471 deaths. The non-randomness of cases (z score = 5.40; P < 0.001) and deaths (z score = 3.83; P < 0.001) were confirmed. Hotspots were identified for cases and deaths in the north and midwest regions of Brazil. Sixteen high-risk space–time clusters were identified for the occurrence of cases with a higher RR = 21.23 (P < 0.001) and four risk clusters for deaths with a higher RR = 80.33 (P < 0.001). These clusters were identified from 22 May and were active until 10 October 2020. The results indicate critical areas in the indigenous territories of Brazil and contribute to better directing the actions of control of COVID-19 in this population.
