A global Pandemic, Preparedness and Response (RRR) architecture
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.

Atherosclerotic lower-extremity peripheral artery disease (PAD) is increasingly recognized as an important cause of cardiovascular morbidity and mortality that affects more than 230 million people worldwide. Traditional cardiovascular risk factors, including advanced age, smoking, and diabetes, are ...strongly linked to an increase risk of PAD. Although PAD has been historically underappreciated compared to coronary artery disease and stroke, greater attention on PAD in recent years has led to important new epidemiologic insights in the areas of thrombosis, inflammation, dyslipidemia, and microvascular disease. In addition, the concept of polyvascular disease, or clinically-evident atherosclerosis in multiple arterial beds, is increasingly identified as a particularly malignant cardiovascular disease worthy of special clinical attention and further study. It is noteworthy that PAD may increase the risk of adverse outcomes in similar or even greater magnitude than coronary disease or stroke. In this review, we highlight important new advances in the epidemiology of PAD with a particular focus on polyvascular disease, emerging biomarkers, and differential risk pathways for PAD compared to other atherosclerotic diseases.

Humanitarian crises exacerbate nutritional risks and often lead to an increase in acute malnutrition. Emergencies include both manmade (conflict) and natural disasters (floods, drought, cyclones, typhoons, earthquakes, volcanic eruptions, etc.). Complex emergencies are combinations of both manmade a...nd natural disasters, often of a protracted nature. Millions of people are affected by humanitarian crises every year. The increasing frequency and scale of emergencies requires nutrition to be addressed in all phases of a response.
Crisis situations, whether acute or protracted, impact on a range of factors that can increase the risk of undernutrition, morbidity, and mortality. They may involve: the large-scale destruction of property and infrastructure; the erosion of livelihood strategies and purchasing power; a breakdown of and reduced access to essential services, including health services, water supply, and sanitation; and the displacement of large numbers of people. Emergencies can also disrupt social systems and the quality of care/feeding practices. Household access to food may be negatively affected and people may find themselves in overcrowded settlements with their families divided. As a result, at the individual level, there is often an increased risk of deteriorating health and nutritional status, resulting in a greater likelihood of death.

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.

Terminology used to describe the transmission of pathogens through the air varies across scientific disciplines, organizations and the general public. While this has been the case for decades, during the coronavirus disease (COVID-19) pandemic, the terms ‘airborne’, ‘airborne transmission’ a...nd ‘aerosol transmission’ were used in different ways by stakeholders in different scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations.
This global technical consultation report brings together viewpoints from experts spanning a range of disciplines with the key objective of seeking consensus regarding the terminology used to describe the transmission of pathogens through the air that can potentially cause infection in humans.
This consultation aimed to identify terminology that could be understood and accepted by different technical disciplines. The agreed process was to develop a consensus document that could be endorsed by global agencies and entities. Despite the complex discussions and challenges, significant progress was made during the consultation process, particularly the consensus on a set of descriptors to describe how pathogens are transmitted through the air and the related modes of transmission. WHO recognizes the important areas where consensus was not achieved and will continue to address these areas in follow-up consultations.

The Public Health Burden of Commercial Tobacco Use
The burden of disease and death from commercial tobacco* use in the United States is
overwhelmingly caused by cigarettes and other combustible tobacco products.
The Public Health Burden of Secondhand Exposure to Commercial Tobacco Smoke Secondhand smoke, the combination of smoke from burning commercial tobacco* products and the smoke breathed out by a person who is smoking, is deadly.
The risk communication and community engagement (RCCE) competency framework is a resource that details the essential behaviours and activities necessary for effective communication and engagement with communities before, during and after public health emergencies. The purpose of this framework is to... establish and promote a common understanding of behavioural competencies and how they should be applied for high-performing and community-centred health emergency programmes. It is intended to support the development of standardized training programmes, professional development and talent acquisition and to enhance the capabilities of public health professionals involved in RCCE. Its goal is to inform the establishment of a skilled, well-trained RCCE workforce that consistently understands and executes the necessary behaviours and activities required to conduct RCCE activities with competence and professionalism.

Chronic kidney disease (CKD) is an important contributor to mortality from noncommunicable diseases. No decrease has been seen for CKD mortality contrary to many other important non-communicable diseases (e.g., cardiovascular disease). The prevalence of CKD and kidney failure are increasing all over... the world – and thereby also the need for dialysis. Unfortunately, the prevalence increases most rapidly in lowand middle-income countries. Globally, there are great inequities in access and quality of management of kidney failure. Many low- and middle-income countries cannot meet the increased need for dialysis. If the patients receive dialysis, it might only be for a limited period due to the out-of-pocket expenses. There are global disparities in CKD mortality reflecting the disparities in access to care. Lack of access to dialysis is an important cause of the increased CKD mortality in low- and middle-income countries.

This threat assessment addresses the implications of the ongoing Marburg virus disease (MVD) outbreak in
Rwanda for the European Union/European Economic Area (EU/EEA). MVD is a severe disease in humans and,
although uncommon, it has the potential to cause epidemics with significant case fatality. ...All recorded MVD
outbreaks to date have originated in Africa. MVD is not an airborne disease and is considered not to be
contagious before symptoms appear. Direct contact with the blood and other body fluids of infected people
and animals or indirect contact with contaminated surfaces and materials like clothing, bedding and medical
equipment is required for transmission. The risk of infection is minimised when proper infection prevention and
control precautions are strictly followed. There is no approved treatment or vaccine for MVD; however, several
pharmaceuticals and candidate MVD vaccines are under investigation.

TNew data from the World Health Organization reveal that the COVID-19 pandemic has disrupted malaria services, leading to a marked increase in cases and deaths.
According to WHO’s latest World malaria report, there were an estimated 241 million malaria cases and 627 000 malaria deaths worldwide i...n 2020. This represents about 14 million more cases in 2020 compared to 2019, and 69 000 more deaths. Approximately two-thirds of these additional deaths (47 000) were linked to disruptions in the provision of malaria prevention, diagnosis and treatment during the pandemic.
As in past years, the report provides an up-to-date assessment of the burden of malaria at global, regional and country levels. It tracks investments in malaria programmes and research as well as progress across all intervention areas. This latest report draws on data from 87 countries and territories with ongoing malaria transmission.
