Many low-resource settings have a shortage of physicians and health workers. (1) In order to provide patient-centred continuous care more effectively, primary care systems can include team-based care strategies in their clinic workflows and protocol...s. Team-based care uses multidisciplinary teams (which may involve new staff, or the shifting of tasks among existing staff). Teams can include patients themselves, primary care physicians, and other allied health professionals, such as nurses, pharmacists, counsellors, social workers, nutritionists, community health workers, or others. Teams reduce the burden on physicians by utilizing the skills of trained health workers. Strong evidence shows that team-based care is effective in improving hypertension control among patients in a cost-effective way. (2) Some amount of task shifting/team-based care is already taking place in many settings; this module provides further guidance on how to maximize this approach for greater impact.

Malaria is an important disease that has a global distribution and significant health burden. The spatial limits ...of its distribution and seasonal activity are sensitive to climate factors, as well as the local capacity to control the disease. Malaria is also one of the few health outcomes that has been modeled by more than one research group and can therefore facilitate the first model intercomparison for health impacts under a future with climate change. We used bias-corrected temperature and rainfall simulations from the Coupled Model Intercomparison Project Phase 5 climate models to compare the metrics of five statistical and dynamical malaria impact models for three future time periods (2030s, 2050s, and 2080s). We evaluated three malaria outcome metrics at global and regional levels: climate suitability, additional population at risk and additional person-months at risk across the model outputs. The malaria projections were based on five different global climate models, each run under four emission scenarios (Representative Concentration Pathways, RCPs) and a single population projection. We also investigated the modeling uncertainty associated with future projections of populations at risk for malaria owing to climate change. Our findings show an overall global net increase in climate suitability and a net increase in the population at risk, but with large uncertainties. The model outputs indicate a net increase in the annual person-months at risk when comparing from RCP2.6 to RCP8.5 from the 2050s to the 2080s. The malaria outcome metrics were highly sensitive to the choice of malaria impact model, especially over the epidemic fringes of the malaria distribution.

Viral hepatitis is defined as inflammation of the liver cells due to viral infection. The burden of liver ...x">disease in South Africa is mostly underestimated as viral hepatitis, in particular chronic infection, is a silent and neglected cause of morbidity and mortality. However, the burden of disease is likely substantial given the prevalence of chronic viral hepatitis. This burden is further compounded by the lack of screening and access to care and treatment as well as inadequate disease surveillance, human and financial resources.
The National Guidelines for the Management of Viral Hepatitis were developed, with the purpose to:
inform healthcare workers in the public and private sectors about the disease, its epidemiology in South Africa and current methods of diagnosis and therapy
strengthen the healthcare response to viral hepatitis
empower communicable diseases workers and stakeholders to make informed decisions regarding appropriate and cost effective interventions

HIV infection, due to the immunosuppressant that leads, nowadays constitutes an aggravating factor of endemic tuberculosis. Tuberculosis remains a huge burden to human health, even in the early 21st... century. The situation is deteriorating in many countries, particularly because of the synergy with the HIV epidemic and the emergence of multidrug-resistant (MDR) and extensively drug resistant (XDR) tuberculosis. The urgent development of new tools that can improve the diagnosis, prevention and/or treatment of tuberculosis and other major mycobacterium diseases depends largely on the progress of basic and applied research. Faced with this situation, there is an urgent need for effective strategies and actions to permanently solve the problem of this endemic disease whose impact is too negative on people’s lives.

Human schistosomiasis otherwise called bilharzia, is a fresh- water snail transmitted intravascular debilitating disease resulting from infection by the parasitic dimorphic Schistosoma trematode worms, which lives in the bloodstream ...ribute-to-highlight medbox">of humans. The World Health Organization (WHO) regards the disease as a neglected tropical disease, with an estimated 732 million persons being vulnerable to infection worldwide in renowned transmission areas. Steinmann and co-workers documented that over 200 million individuals from Africa, Asia, and South America are infected with this disease. The WHO further estimated that schistosome infections and geohelminths accounts for over 40% of the world tropical disease burden with the exclusion of malaria. Humans get infected with this disease when they make contact with water contaminated with the skin-penetrating cercariae. Prevalence of schistosomiasis, at present, is still high in sub-Saharan Africa. In 2008, 17.5 million people were treated globally for schistosomiasis, 11.7 million of those from sub-Saharan Africa only. Approximately 120 million individuals in sub-Saharan Africa have schistosomiasis-related symptoms while about 20 million undergo hardship as a result of chronic presentations of the disease.

Lymphatic filariasis (LF), a neglected tropical disease, is targeted for global elimination as a public health problem. This article reviews the history of LF control and elimination activities in t...he countries of the World Health Organization's (WHO) Eastern Mediterranean Region (EMR) over the last 2 decades. In 2000, the estimated at-risk population in EMR countries was 12.6 million people, accounting for approximately 1% of the global disease burden. Of the 22 EMR countries, 3 countries (Egypt, Sudan and Yemen) were LF endemic and the disease was suspected in 4 other countries (Djibouti, Oman, Somalia and Saudi Arabia). After almost 2 decades of implementing sustained control and prevention measures, Egypt and Yemen were successfully validated by the WHO as having achieved the elimination criteria in 2017 and 2019, respectively. In 2018, Sudan completed mapping of LF, reaching 26.2% geographical coverage where mass drug administration (MDA) is required and is scaling-up MDA. Extensive epidemiological assessment indicated the absence of LF transmission in the four suspected countries and no MDA required. Challenges faced during the elimination and post-elimination phases are described and discussed

The Government of the Republic of Zambia has placed priority on ensuring that Zambians are healthy and productive as a catalyst to the attainment of...> socioeconomic development . The Vision 2030 aims to transform Zambia into a prosperous middle-income country as articulated also in the 7th National Develop-ment Plan (7NDP) and National Health Strategic Plan 2017 – 2021 (NHSP 2017-2020). However, this aspiration is threatened by the double burden of Communicable and Non-Communicable Diseas¬es. Zambia has been recording an increase in morbidity and mortality due to Non-Communicable Diseases (NCDs) such as cancers, diabetes, chronic respiratory and cardiovascular diseases. According to the 2016 WHO NCD country profiles, 29% of all deaths in Zambia are attributed to NCDs. This is unacceptably high, considering that most of these diseases can be reduced by modifying four main behavioural risk factors for NCDs which are tobacco use, harmful use of alcohol, unhealthy diets and physical inactivity.

Noncommunicable diseases (NCDs) such as cancer, cardiovascular disease, diabetes and chronic respiratory diseases and their risk factors are an inc...reasing public health and development challenge in Kazakhstan. This report provides evidence through three analyses that NCDs reduce economic output and discusses potential options in response, outlining details of their relative returns on investment. An economic burden analysis shows that economic losses from NCDs (direct and indirect costs) comprise 2.3 trillion tenge, equivalent to 4.5% of gross domestic product in 2017. An intervention costing analysis provides an estimate of the funding required to implement a set of policy interventions for prevention and clinical interventions. A cost–benefit analysis compares these implementation costs with the estimated health gains and identifies which policy packages would give the greatest returns on investment. For example, the salt policy package achieved a benefit-to-cost ratio of 118.4 over 15 years, a return of more than 118 tenge for every 1 tenge invested.

Cryptococcal disease, particularly cryptococcal meningitis is a significant cause of morbidity and mortality among people living with HIV with advanced HIV ...">disease. It is estimated that it is responsible for nearly 19% of AIDS-related mortality, second only to tuberculosis. Rapid screening, diagnosis and linking to appropriate treatment are critical actions national programs must take to reduce the burden of disease.
WHO in 2022 introduced updated guidelines for diagnosing, preventing, and managing cryptococcal disease among adults, adolescents and children living with HIV. This policy brief provides a summary of the key recommendations, clinical considerations, and also stresses the importance of ensuring access to life-saving antifungals. There is an urgent need for countries to scale-up management for not just cryptococcal meningitis, but address cryptococcal disease in the context of a package of care for advanced HIV disease as recommended by WHO.

Background
Low- and middle-income countries now experience the highest prevalence and mortality rates of cardiovascular disease.
Main text
While improving the availability and delivery ...ass="attribute-to-highlight medbox">of proven, effective therapies will no doubt mitigate this burden, we posit that studies evaluating cardiovascular disease risk factors, management strategies and service delivery, in diverse settings and diverse populations, are equally critical to improving outcomes in low- and middle-income countries. Focusing on examples drawn from four cardiovascular diseases — coronary artery disease, stroke, diabetes and kidney disease — we argue that ethnicity, culture and context matter in determining the risk factors for disease as well as the comparative effectiveness of medications and other interventions, particularly diet and lifestyle interventions.
Conclusion
We believe that a host of cohort studies and randomized control trials currently being conducted or planned in low- and middle-income countries, focusing on previously understudied race/ethnic groups, have the potential to increase knowledge about the cause(s) and management of cardiovascular diseases across the world.

Time has seen management for Cystic Fibrosis (CF) advance drastically, most recently in the development of the disease-modifying triple combination therapy ivacaftor/tezacaftor/elexacaftor. There is... currently limited evidence regarding both the global epidemiology of CF and access to this transformative therapy - and therefore where needs are not being met. Therefore, this study aims to define gaps in access to CF treatment. The results show that a significant CF patient burden exists in countries where disease-modifying drugs are unavailable, and final figures are likely underestimates. This analysis shows the potential to improve rates of diagnosis and treatment for CF, so a higher percentage of patients receive the most effective triple combination treatment.

Volume 3, Cancer, presents the complex patterns of cancer incidence and death around the world and evidence on effective and cost-effective ways to control cancers. The DCP3 evaluation of cancer wil...l indicate where cancer treatment is ineffective and wasteful, and offer alternative cancer care packages that are cost-effective and suited to low-resource settings. Main messages from the volume include:
-Quality matters in all aspects of cancer treatment and palliation.
-Cancer registries that track incidence, mortality, and survival paired with systems to capture causes of death are important to understanding the national cancer burden and the effect of interventions over time.
-Effective interventions exist at a range of prices. Adopting ‘resource appropriate’ measures which allow the most effective treatment for the greatest number of people will be advantageous to countries.
-Prioritizing resources toward early stage and curable cancers is likely to have the greatest health impact in low income settings.
-Research prioritization is no longer just a global responsibility.
