In all our work, an emphasis is placed on building partnerships for change among international agencies, governments, nongovernmental organizations, corporations, national ministries of health, and most of all, with people at the grass roots. We help people acquire the tools, knowledge, and resources they need to transform their own lives, building a more peaceful and healthier world for us all.
Les chaînes de transmission. Au mois de mai 2020, une épidémie d'encéphalite a éclaté dans l'Ain, à cause de… fromage de chèvre. En réalité, c'est toute une chaîne de transmission entre espèces animales qui s'est établie, jusqu'aux humains. En effet, comme le montre une enquête de Santé Publique France, l'encéphalite a été causée par des tiques, qui l'ont transmis à des troupeaux de chèvres du bassin d'Oyonnax. Le virus s'est ensuite propagé chez l'Homme par la production de fromage. Ces chaînes de transmission sont fréquentes chez les maladies qui touchent les humains (certaines grippes, potentiellement le nouveau coronavirus, etc.) et la compréhension des mécanismes de transmission inter-espèces est primordiale pour aider à développer de meilleurs traitements.
The meaning of health has evolved over time. In keeping with the biomedical perspective, early definitions of health focused on the theme of the body's ability to function; health was seen as a state of normal function that could be disrupted from time to time by disease. An example of such a definition of health is: "a state characterized by anatomic, physiologic, and psychological integrity; ability to perform personally valued family, work, and community roles; ability to deal with physical, biological, psychological, and social stress".[2] Then in 1948, in a radical departure from previous definitions, the World Health Organization (WHO) proposed a definition that aimed higher: linking health to well-being, in terms of "physical, mental, and social well-being, and not merely the absence of disease and infirmity".[3] Although this definition was welcomed by some as being innovative, it was also criticized as being vague, excessively broad and was not construed as measurable. For a long time, it was set aside as an impractical ideal and most discussions of health returned to the practicality of the biomedical model.[4]

Vient ensuite la question de la prévention. Olivier Geffard, directeur de recherche de l'unité RiverLy a pour mission la surveillance chimique des milieux aquatiques, “dans l'objectif de s'assurer du maintien de la santé des écosystèmes aquatiques”. Cette surveillance repose sur la mesure des taux de micropolluants (hydrocarbures, pesticides, etc.) sur certaines zones aquatiques, à l'aide de l'étude de l'intérieur des organismes vivants dans ces zones, qui concentrent les contaminants. “Cette approche du biologique permet une meilleure caractérisation de la contamination chimique de l'eau [par rapport à une analyse du taux de polluants dans un volume d'eau]”, explique Olivier Geffard.
Body cleansing and detoxification have been referred to as an elaborate hoax used by con artists to cure nonexistent illnesses. Most doctors contend that the 'toxins' in question do not even exist.[16][17] In response, alternative medicine proponents frequently cite heavy metals or pesticides as the source of toxification, however no evidence exists that detoxification approaches have a measurable effect on these or any other chemical levels. Medical experts state that body cleansing is unnecessary as the human body is naturally capable of maintaining itself, with several organs dedicated to cleansing the blood and gut.[18]
Focusing more on lifestyle issues and their relationships with functional health, data from the Alameda County Study suggested that people can improve their health via exercise, enough sleep, spending time in nature, maintaining a healthy body weight, limiting alcohol use, and avoiding smoking.[22] Health and illness can co-exist, as even people with multiple chronic diseases or terminal illnesses can consider themselves healthy.[23]
Generally, the context in which an individual lives is of great importance for both his health status and quality of life. It is increasingly recognized that health is maintained and improved not only through the advancement and application of health science, but also through the efforts and intelligent lifestyle choices of the individual and society. According to the World Health Organization, the main determinants of health include the social and economic environment, the physical environment and the person's individual characteristics and behaviors.[13]
An increasing number of studies and reports from different organizations and contexts examine the linkages between health and different factors, including lifestyles, environments, health care organization and health policy, one specific health policy brought into many countries in recent years was the introduction of the sugar tax. Beverage taxes came into light with increasing concerns about obesity, particularly among youth. Sugar-sweetened beverages have become a target of anti-obesity initiatives with increasing evidence of their link to obesity.[16]– such as the 1974 Lalonde report from Canada;[15] the Alameda County Study in California;[17] and the series of World Health Reports of the World Health Organization, which focuses on global health issues including access to health care and improving public health outcomes, especially in developing countries.[18]
In addition to safety risks, many jobs also present risks of disease, illness and other long-term health problems. Among the most common occupational diseases are various forms of pneumoconiosis, including silicosis and coal worker's pneumoconiosis (black lung disease). Asthma is another respiratory illness that many workers are vulnerable to. Workers may also be vulnerable to skin diseases, including eczema, dermatitis, urticaria, sunburn, and skin cancer.[57][58] Other occupational diseases of concern include carpal tunnel syndrome and lead poisoning.
