Fièvre aphteuse, influenza aviaire ou encore fièvre catarrhale ovine, comme l'ont montré les crises sanitaires de la dernière décennie, il est essentiel de disposer de systèmes de lutte organisés et réactifs contre les agents pathogènes exotiques.

ANSES 22/05/12 Introduction de maladies animales exotiques en France : des recommandations pour améliorer la surveillance et la prévention .

Afin d'identifier les maladies exotiques les plus à risque d'introduction en France et de préciser les modalités de lutte et de surveillance les plus adaptées contre ces agents, l'Anses s'est auto-saisie. Elle publie aujourd'hui les résultats de ses travaux et les recommandations qu'elle en tire. La santé des animaux est susceptible d'être menacée par divers agents pathogènes (bactéries, virus, parasites) dont certains peuvent également affecter la santé humaine (agents zoonotiques).

Parmi ces agents pathogènes, un certain nombre sont présents sur le territoire métropolitain, d'autres circulent hors du territoire et sont dits "exotiques". Dans ce contexte, l'Anses a souhaité s'autosaisir. PLOS 22/06/16 The Epidemiology of Rift Valley Fever in Mayotte: Insights and Perspectives from 11 Years of Data. Abstract Rift Valley fever (RVF) is a zoonotic arboviral disease that is a threat to human health, animal health and production, mainly in Sub-Saharan Africa.

PLOS 22/06/16 The Epidemiology of Rift Valley Fever in Mayotte: Insights and Perspectives from 11 Years of Data

RVF virus dynamics have been poorly studied due to data scarcity. On the island of Mayotte in the Indian Ocean, off the Southeastern African coast, RVF has been present since at least 2004. Several retrospective and prospective serological surveys in livestock have been conducted over eleven years (2004–15). These data are collated and presented here. Author Summary.

PLOS 06/07/15 A Stochastic Model to Study Rift Valley Fever Persistence with Different Seasonal Patterns of Vector Abundance: New Insights on the Endemicity in the Tropical Island of Mayotte. Abstract Rift Valley fever (RVF) is a zoonotic vector-borne disease causing abortion storms in cattle and human epidemics in Africa.

PLOS 06/07/15 A Stochastic Model to Study Rift Valley Fever Persistence with Different Seasonal Patterns of Vector Abundance: New Insights on the Endemicity in the Tropical Island of Mayotte

Our aim was to evaluate RVF persistence in a seasonal and isolated population and to apply it to Mayotte Island (Indian Ocean), where the virus was still silently circulating four years after its last known introduction in 2007. We proposed a stochastic model to estimate RVF persistence over several years and under four seasonal patterns of vector abundance. Firstly, the model predicted a wide range of virus spread patterns, from obligate persistence in a constant or tropical environment (without needing vertical transmission or reintroduction) to frequent extinctions in a drier climate. We then identified for each scenario of seasonality the parameters that most influenced prediction variations.

PLOS 30/09/13 Rift Valley Fever in Humans and Animals in Mayotte, an Endemic Situation? Retrospective studies and surveillance on humans and animals revealed that Rift Valley Fever virus (RVFV) has been circulating on Mayotte for at least several years.

PLOS 30/09/13 Rift Valley Fever in Humans and Animals in Mayotte, an Endemic Situation?

A study was conducted in 2011 to estimate the seroprevalence of RVF in humans and in animals and to identify associated risk factors. Using a multistage cluster sampling method, 1420 individuals were enrolled in the human study, including 337 children aged 5 to 14 years. For the animal study, 198 seronegative ruminants from 33 randomly selected sentinel ruminant herds were followed up for more than one year. In both studies, information on environment and risk factors was collected through a standardized questionnaire. The overall weighted seroprevalence of RVFV antibodies in the general population aged ≥5 years was 3.5% (95% CI 2.6–4.8). Figures Citation: Lernout T, Cardinale E, Jego M, Desprès P, Collet L, et al.

Appréciation du risque d'émergence de la fièvre de la vallée du Rift en France métropolitaine. Thèse d'exercice, Médecine vétérinaire, Ecole Nationale Vétérinaire de Toulouse - ENVT, 2011, 153 p. La fièvre de la vallée du Rift est une arbovirose zoonotique, causée par un Phlebovirus (Bunyaviridae), et d’une grande importance sanitaire et économique. Isolée au Kenya en 1930, elle s’est depuis répandue largement en Afrique puis a émergé au Moyent-Orient dans les années 2000, et dans certaines îles de l’Océan Indien en 2007.

Ce phénomène d’extension intervient dans un contexte de changement global favorable à la dissémination des arbovirus.

Cattle are socially important in Republic of Comoros because massive slaughtering occurs during traditional wedding ceremonies known as “Grands Mariages,” especially on the main island, Grande Comore. We report results from a serosurvey of the ruminant populations on the 3 islands of the Republic of Comoros during the 2009 dry season (April–August). Matthieu Roger Acknowledgments References.
