Le Retour des épidémies

Il y a encore trop peu d’ouvrages sur la santé mondiale écrits en français pour ne pas se féliciter de la publication récente (août 2015) du Retour des épidémies, d’Auriane Guilbaud, maître de conférences en science politique à l’université Paris-8, et Philippe Sansonetti, pastorien, professeur au Collège de France et titulaire de la chaire Microbiologie et maladies infectieuses. Auriane Guilbaud et Philippe Sansonetti évoquent, en une centaine de pages, la peur d’un retour vers un « âge ...

L’écologie, une donnée majeure pour la recherche sur les virus

Ainsi que le rappelait Hervé Kempf dans un récent ouvrage [1], la conquête des Amériques par les conquistadores espagnols au XVIe siècle ne tient pas tant à leur expérience militaire et leur maîtrise du canon qu’à leur adaptation de longue date à un large éventail de maladies et autres agressions virales qu’ils apportèrent avec eux dans ce nouveau monde. Ces « hôtes imprévus, écrit-il, se révélèrent la plus terrible arme de guerre que l’humanité ait jamais connue ». Il ...

Les Nouvelles Menaces des maladies infectieuses émergentes

Une réflexion prospective sur les menaces sanitaires est devenue plus nécessaire que jamais, explique Fabienne Keller, la rapporteuse de cette étude qui vise à alerter sur les risques liés à l’appa­rition et la réapparition de maladies infectieuses. Le rapport dresse un inventaire des travaux existants sur le sujet, recueille les recommandations d’instituts et d’experts, puis identifie les variables déterminantes dans l’évolution des maladies émergentes.  Depuis 50 ans, le nombre de maladies émergentes (dont 75 % sont ...

Hospitalization in the case of Infectious Diseases

“Infectious diseases are part of human life,” stress Didier Raoult and Jean-Paul Segade in this article. When some disappear, thanks to antibiotics or vaccination, others emerge in new forms. After plague and cholera, human beings must do battle today not only with HIV/AIDS, but also with respiratory infections and acute diarrhoea, two forms of particularly epidemic infectious diseases.

Raoult and Segade are insistent, then, that the question of special care for these contagious patients is unavoidable today (hospitalization in specialist departments, in individual rooms, with vaccinated, sensitized staff etc.), particularly as two new epidemics have been developing for some years: the so-called “hospital infections” (linked to the development of multiresistant bacteria) and “imported” epidemics (chikungunya, avian flu, staphylococcus aureus etc.).

In this context, and with the aim of limiting the spread of these diseases, Didier Raoult and Jean-Paul Segade formulate a number of lines of thinking here, particularly in relation to hospital organization.

The Challenge of Infectious Diseases

By way of introduction to our special dossier on infectious diseases, Nicolas Simon reminds us here of some of the dramatic episodes they have occasioned in the past. He also points up the successes achieved in the struggle against smallpox, for example, while underscoring the extent of the HIV/AIDS and malaria epidemics, which mainly affect populations in the less developed countries.
However, he stresses the scale of the effort put in by the international community since the mid-1990s and the beneficial effects that have ensued. He thus shows how disastrous it would be if that effort slackened and stresses, in very timely fashion, the need to continue with and, indeed, intensify it. He also emphasizes the lead role certain countries and the NGOs and foundations can play to this effect, including through an institution as remarkable as the “Global Fund to Fight AIDS, Tuberculosis and Malaria”. But let us make no mistake, says Nicolas Simon, it is, once again, a question of priorities.

The Battle against Malaria. A Victory that is within Reach

Having remained silent about, and absent from, the struggle against malaria for a long period, the international community finally roused itself in the late 1990s and began to combat the disease on a “massive” scale. It is an illness entirely eradicated in the advanced countries, but one that still rages in poor ones, with almost a million dying each year, mainly in sub-Saharan Africa. It attacks those who are most vulnerable: namely, women, the under-fives, those with HIV/AIDS and displaced people.
Malaria is a “disease of poverty”, as Michèle Barzach and Sylvie Chantereau stress here. “As an individual and collective factor of social destabilization”, it hits the countries it affects hard in both economic and social terms. “Malaria can account for more than 50% of the expenditure of households coping with it directly”, note the authors. It is estimated to cost “sub-Saharan Africa more than 12 billion dollars in lost GDP”.
Yet it is an avoidable disease, thanks to some effective treatments and means of prevention, observe Michèle Barzach and Sylvie Chantereau. This is something the international community has realized, having for some ten years now carried on an unprecedented struggle against malaria, with funding that has risen from less than 100 million dollars in 2003 to 2 billion in 2009. In this context, the authors assert without hesitation that “all the conditions are in place today for malaria to be effectively controlled in all the affected areas of the globe, and even eliminated in some countries”. They stress, however, that the current research and funding effort has to be maintained if this is to happen.

The Risks of an Influenza Pandemic: 2009 and After…

In March 2009, there was an outbreak of the Influenza A (H1N1) virus in Mexico. By the end of May it had killed 45 Mexicans, contaminated almost 3,800 and there were more than 10,000 confirmed cases throughout the world, 5,500 of them in the United States. On 11 June, with the virus affecting more than 27,000 persons in 74 countries, the World Health Organization (WHO) declared a level 6 maximum alert or, in other words, a state of global pandemic.
This pandemic turned out to be a “very active epidemic of moderate seriousness, but temporally atypical,’ as William Dab and Nina Testut put it here, stressing the unpredictable character of the development of all influenza viruses. “The management of influenza epidemics is basically a management of uncertainty”, say the authors, going on to observe that “it is impossible to manage a health security risk that includes a significant degree of uncertainty without the trust of stakeholders”.
Given this observation, William Dab et Nina Testut make an initial assessment of the way the pandemic was managed in France, define the reasons for — and role of — the “wave of polemics” that has accompanied this health crisis since last Summer, and examine the way the French perceived these various elements. “This H1N1 virus will, in the end, have taught us much we didn’t know about French society”, stress the two authors.

La menace de pandémies, facteur d’incertitude économique

Depuis plusieurs années, la menace d’une pandémie s’est faite plus pressante comme en témoigne l’irruption de la grippe A au Mexique. Puisque les données médicales sont encore trop parcellaires pour déterminer son ampleur et sa gravité, il se révèle impossible d’évaluer précisément l’impact économique de la grippe A et donc plus généralement des pandémies grippales. Néanmoins, plusieurs remarques peuvent être faites à ce stade. Après avoir recensé les différents types d’impact économique, certains épisodes ...

Les nouveaux risques infectieux

The New Infectious Risk

Doctor Ducel shows us, alas, that far from having disappeared, the risks from infectious disease are increasing :
- old ones are surging back (tuberculosis in particular), primarily due to relaxation of efforts to detect and prevent, but also because disease organisms find the right host for spreading (more than two billion people could be struck down by TB!) ;
- infections contracted in hospital, called nosocomial infections, have soared to unprecedented heights, not only because of contaminated blood transfusions but for multiple other reasons the account of which is alarming ;
- new agents of infectious risk, moreover, appear to be resistant to the antibiotics on which we rested so much hope : whether because these medications are administered wrongly and everywhere, or, evolution being still more worrisome, because new pathogenic micro-organisms are spreading, bacteria which "develop muscles" to resist antibiotics or transform themselves to overcome the defenses of man and his pharmaceutical arsenal.
The new infectious risks throw a major challenge at medicine and pharmacology. It is heavy with consequences for sanitation and social planning, but also with economic and scientific implications. The author explains them in a manner that is both convincing and worrying.

La santé sans la médecine est-ce prévisible ?

On peut exploiter les notions darwiniennes pour décrire et quantifier la concurrence des maladies entre elles en fonction du nombre de leurs victimes. Par ailleurs, la société dispose de mécanismes d'auto-guérison et d'autorégulation qui contraignent au minimum le taux annuel de mortalité. Ce qui fait que les "vieilles" maladies perdent de l'importance, alors que les maladies dites "jeunes" gagnent du terrain. L'évolution d'une maladie est un processus de croissance naturel et, par conséquent, prévisible. La ...
