Non-communicable diseases (NCDs) are the second common cause of death in sub-Saharan Africa (SSA) accounting for about 35% of all deaths, after a composite of communicable, maternal, neonatal, and nutritional diseases. Despite prior perception of low NCDs mortality rates, current evidence suggests t...hat SSA is now at the dawn of the epidemiological transition with contemporary double burden of disease from NCDs and communicable diseases. In SSA, cardiovascular diseases (CVDs) are the most frequent causes of NCDs deaths, responsible for approximately 13% of all deaths and 37% of all NCDs deaths. Although ischemic heart disease (IHD) has been identified as the leading cause of CVDs mortality in SSA followed by stroke and hypertensive heart disease from statistical models, real field data suggest IHD rates are still relatively low. The neglected endemic CVDs of SSA such as endomyocardial fibrosis and rheumatic heart disease as well as congenital heart diseases remain unconquered. While the underlying aetiology of heart failure among adults in high-income countries (HIC) is IHD, in SSA the leading causes are hypertensive heart disease, cardiomyopathy, rheumatic heart disease, and congenital heart diseases. Of concern is the tendency of CVDs to occur at younger ages in SSA populations, approximately two decades earlier compared to HIC. Obstacles hampering primary and secondary prevention of CVDs in SSA include insufficient health care systems and infrastructure, scarcity of cardiac professionals, skewed budget allocation and disproportionate prioritization away from NCDs, high cost of cardiac treatments and interventions coupled with rarity of health insurance systems. This review gives an overview of the descriptive epidemiology of CVDs in SSA, while contrasting with the HIC and highlighting impediments to their management and making recommendations.

This guideline provides global, evidence-informed recommendations on daily iron supplementation in infants and children, as a public-health intervention for the prevention of anaemia and iron deficiency. It includes recommendations for iron supplementation in countries where malaria is prevalent.
The Committee discussed the implications for preparedness for smallpox-like events reflected by the ongoing COVID-19 pandemic. The Committee noted how quickly diagnostics and vaccines could be developed and deployed when resources and political will were abundant. This rapidity was also due to the f...act that the genetic sequence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had been shared worldwide. It was noted that in one country SARS-CoV-2 had been reconstructed in a laboratory from the viral genome sequence before the first case of COVID-19 had been reported, highlighting the benefits of synthetic biology technologies for accelerated development of diagnostics as well as the oft-described potential risks. Lessons learned about clinical care during the COVID-19 pandemic were also discussed.

Leishmaniasis is a climate-sensitive disease. Changes in temperature, rainfall, and humidity can have strong impacts on
the sandfly vector, altering their distribution and influencing their survival and population sizes. Increased temperatures shorten vector development time, reduce Leishmania para...site incubation time, and increase vector biting rates, allowing transmission
in areas not previously endemic for the disease. Poor and
marginalized communities will be hit disproportionately harder by
the effects of climate change, and droughts, famines, and floods
can also lead to displacement and migration of immunologically
naive people to areas where leishmaniasis is endemic, posing a
threat of leishmaniasis outbreaks.

As the Americas undergo profound demographic change and there are more persons aged 65 years or older than children younger than 5 years, it is crucial to recognize that national immunization programs must be redesigned to ensure comprehensive protection for individuals across the lifespan. By adopt...ing a life course approach (LCA) to immunization, vaccination programs can be tailored to close immunity gaps at different stages of life. The life course approach foresees the establishment of multiple strategies to reduce missed opportunities for vaccination according to age group. This technical document explains the key concepts of the LCA with a focus on immunization by vaccination, as well as the underlying biological mechanisms that require the application different vaccines at different life stages according to changes to the immune system and in the epidemiological situation of a community.

Barriers to the prompt and effective diagnosis and treatment of malaria exist at both the community and health facility level. Household surveys measure malaria case management at the population level with standard indicators that assess treatment-seeking behavior, access to diagnostic testing, and ...access to appropriate treatment. Performance on these indicators varies widely from country to country. Among countries with Demographic and Health Surveys (DHS) or Malaria Indicator Surveys (MIS) completed between 2014 and 2016, advice and treatment was sought for a median of 47% of children under age 5 with fever.

Building on the 2021 Interim guidance, this second version and update, incorporates the lessons and feedback from the hepatitis pilots that successfully demonstrated the feasibility of measuring hepatitis B and C impact targets to demonstrate elimination, whilst highlighting challenges caused by hig...h disease burden in some countries, as well as delays in reaching mortality targets due to the long natural history of disease progression to liver cirrhosis and hepatocellular carcinoma.
The path to elimination provides a framework with 3 levels of achievements for which WHO certification is available. Each stepwise progression from bronze to silver to gold tiers will promote an iterative expansion of prevention, diagnosis and treatment services for viral hepatitis services and strengthen measurement systems to support attainment of the 2030 elimination goals.
This updated version also includes changes, clarifications and new guidance on alternative measurement approaches for country validation of elimination. Through the validation process, WHO and partners continue to provide country support for strengthening health system capacity and patient-centred services that respect and protect the human rights of people living with viral hepatitis and ensures meaningful engagement of communities in the national, regional and global viral hepatitis response.

The pharmacological management of asthma has changed considerably in recent decades, as it has come to be understood that it is a complex, heterogeneous disease with different phenotypes and endotypes. It is now clear that the goal of asthma treatment should be to achieve and maintain control of the... disease, as well as to minimize the risks (of exacerbations, disease instability, accelerated loss of lung function, and adverse treatment effects). That requires an approach that is personalized in terms of the pharmacological treatment, patient education, written action plan, training in correct inhaler use, and review of the inhaler technique at each office visit. A panel of 22 pulmonologists was invited to perform a critical review of recent evidence of pharmacological treatment of asthma and to prepare this set of recommendations, a treatment guide tailored to use in Brazil. The topics or questions related to the most significant changes in concepts, and consequently in the management of asthma in clinical practice, were chosen by a panel of experts. To formulate these recommendations, we asked each expert to perform a critical review of a topic or to respond to a question, on the basis of evidence in the literature. In a second phase, three experts discussed and structured all texts submitted by the others. That was followed by a third phase, in which all of the experts reviewed and discussed each recommendation. These recommendations, which are intended for physicians involved in the treatment of asthma, apply to asthma patients of all ages.

In this report a nutrition governance framework was applied to research and analyse the provincial experience with nutrition policy in Pakistan, looking both at chronic and acute malnutrition. Twenty-one in-depth interviews with key stakeholders were also conducted along with a review of published a...nd grey literature. Findings were validated and supplemented by consultative provincial roundtable meetings. Punjab’s nutritional puzzle is that it has high levels of chronic malnutrition and micro-nutrient deficiencies despite a surplus production of food and a low poverty level. Under-nutrition is mainly linked to insufficient attention to preventive health strategies and to a lack of connection between relevant sectors such as Education, Health, Poverty, Safe Water and Sanitation, and Food. Strategic opportunities are recommended which include cross-party political support and ownership for nutrition, with steering by executive leadership; multi-sectoral action and functional integration of various departments and programmes with the creation of a central convening structure for effective cross-sectoral coordination; broadening of nutritional activities beyond salt iodization and vitamin A coverage; central co-ordination of monitoring and evaluation and effective partnerships between the state and non-state sector around data production, awareness, advocacy, and monitoring.
