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.

Since the description of the first case of COVID-19 in Wuhan, Hubei province in China, in December 2019, much knowledge has been accumulated about the dynamics of evolution of the SARS-CoV-2 virus, contagion, disease progression, prevention and treatment.
As the world population is growing and health care resources are in high demand the pressure on medical services is becoming higher. Developing countries are already at a crisis point in health care provision, and time demands a new approach in structuring medical resources. Primary care is t...he vital pillar for fundamental health care at community level and has been deemed as a cost-effective modality. In the West the primary care physician manages chronic medical conditions in communities and therefore reduces unnecessary hospital admissions. In the West, the primary care system is extremely well organised. Low-income countries must improve teaching, training and funding in primary care. In this article the urgent need for primary care is discussed in developing countries, and ways to minimise costs and improve clinical outcomes at community level.

As the global community aims to fulfill its commitments to the UN Sustainable Development Goals, and the achievement of universal health coverage, dozens of countries have committed to the expansion of community health workers (CHWs) as the front line of their healthcare systems [1, 2]. Robust resea...rch demonstrates CHWs improve access to care, reduce maternal, newborn, and child mortality, improve clinical outcomes for chronic diseases, and prevent disease outbreaks [3].
To support the operationalization of quality CHW program design and implementation, USAID, UNICEF, the Community Health Impact Coalition, and Initiatives Inc. have updated and adapted the Community Health Worker Assessment and Improvement Matrix (CHW AIM) Program Functionality Matrix [12]. This tool can be used to identify design and implementation gaps in both small- and national-scale CHW programs, and close gaps in policy and practice.

Despite the considerable improvement in global health, millions of people still lack access to quality health services, including access to effective antimicrobial medicines, or are impoverished as a result of health spending. At the same time, antimicrobial resistance – a consequence of overuse a...nd misuse of antimicrobials – is increasingly a barrier to accessing effective care. The declining effectiveness of antibiotics is driven by multiple factors, many of which can be addressed through well functioning primary health care. However, primary health care has not always had much attention in national health sector responses to
antimicrobial resistance, which often focus on tertiary care, laboratory detection and surveillance. The three pillars of primary health care (community engagement, front-line health services including primary care and essential public health, and multisectoral action on wider health determinants) are central not just to Universal Health Coverage and the Sustainable Development Goals, but also to an effective response to antimicrobial resistance.

This paper reviews the effects of vertical responses to COVID-19 on health systems, services, and people’s access to and use of them in LMICs, where historic and ongoing under-investments heighten vulnerability to a multiplicity of health threats. We use the term ‘vertical response’ to describ...e decisions, measures and actions taken solely with the purpose of preventing and containing COVID-19, often without adequate consideration of how this affects the wider health system and pre-existing resource constraints.

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.

Most of the global burden of sepsis occurs in low- and middle-income countries (LMICs), but the prevalence and etiology of sepsis in LMICs are not well understood. In particular, the lack of laboratory infrastructure in many LMICs has historically precluded an assessment of the pathogens leading to ...sepsis. A recent systematic review found that data describing antimicrobial resistance were absent for 43% of countries in Africa, and only two countries have national antimicrobial resistance plans. In addition, small studies have identified indiscriminate antibiotic use both in and out of hospital settings in sub-Saharan Africa. The absence of microbiological data and lack of antibiotic stewardship complicate sepsis management and almost certainly worsens outcomes, particularly in low-resource systems. The purpose of this study was to examine the prevalence, etiology, and outcomes of sepsis among a cohort of critically ill patients in a referral hospital of Malawi, with a focus on the prevalence of culture-confirmed bacteremia and urinary tract infections.

Many features of the environment have been found to exert an important influence on cardiovascular disease (CVD) risk, progression, and severity. Changes in the environment due to migration to different geographic locations, modifications in lifestyle choices, and shifts in social policies and cultu...ral practices alter CVD risk, even in the absence of genetic changes. Nevertheless, the cumulative impact of the environment on CVD risk has been difficult to assess
and the mechanisms by which some environment factors influence CVD remain obscure. Human environments are complex; and their natural, social and personal domains are highly variable due to diversity in human ecosystems, evolutionary histories, social structures, and individual choices. Accumulating evidence supports the notion that ecological features such as the diurnal cycles of
light and day, sunlight exposure, seasons, and geographic characteristics of the natural environment such altitude, latitude and greenspaces are important determinants of cardiovascular health and CVD risk. In highly developed societies, the influence of the natural environment is moderated by the physical characteristics of the social environments such as the built environment
and pollution, as well as by socioeconomic status and social networks. These attributes of the
social environment shape lifestyle choices that significantly modify CVD risk. An understanding
of how different domains of the environment, individually and collectively, affect CVD risk could
lead to a better appraisal of CVD, and aid in the development of new preventive and therapeutic
strategies to limit the increasingly high global burden of heart disease and stroke.

Cardiovascular disease (CVD) is the leading cause of global deaths, with the majority occurring in low- and middle-income countries (LMIC). The primary and secondary prevention of CVD is suboptimal throughout the world, but the evidence-practice gaps are much more pronounced in LMIC. Barriers at the... patient, health-care provider, and health system level prevent the implementation of optimal primary and secondary prevention. Identification of the particular barriers that exist in resource-constrained settings is necessary to inform effective strategies to reduce the identified evidence-practice gaps. Furthermore, targeting modifiable factors that contribute most significantly to the global burden of CVD, including tobacco use, hypertension, and secondary prevention for CVD will lead to the biggest gains in mortality reduction. We review a select number of novel, resource-efficient strategies to reduce premature mortality from CVD, including: (1) effective measures for tobacco control; (2) implementation of simplified screening and management algorithms for those with or at risk of CVD, (3) increasing the availability and affordability of simplified and cost-effective treatment regimens including combination CVD preventive drug therapy, and (4) simplified delivery of health care through task-sharing (non-physician health workers) and optimizing self-management (treatment supporters). Developing and deploying systems of care that address barriers related to the above, will lead to substantial reductions in CVD and related mortality.
