PREVISION JOURNALIERE DES POLLENS SUR LE TERRITOIRE NATIONAL FRANÇAIS, AVEC UN OBJECTIF D'INFORMATION SANITAIRE DES POPULATIONS ALLERGIQUES

Abstract : At present, 16% of French people suffer from allergies to one or several pollens. The corresponding symptoms can be presented as under benign form (rhinitis, conjunctivitis, cough) as under much more serious form : asthma. Forecast of the starting date of an allergic exposure risk to pollens is necessary from a sanitary and preventive standpoint. Forecast has to be more precisely as possible in order to begin anti-allergic treatments at appropriate moment, with a view of effectiveness and reduction of the costs due to this disease. The present study, taking place in all the French territory, concerns four pollen taxa among the most allergenic : ash, birch, grasses and ragweed. This work comprises three parts. The first one consists of a global presentation of pollen data with a description of pollen collection and analysis methods, a study of the pollen series quality and the various problems found and, finally, it consists of a detailed description of the four taxa of the study including their geographical distribution. The second part describes various determining criteria of the beginning of the pollen season, and different forecast methods of this one. Finally, the third part collects all the results, for the four-concerned taxa, been due to the selected forecast methods applied to longest pollen series. This final part mainly focuses on the interest of each of the selected methods, the quality of models associated to each one and the efficiency of these models in a preventive perspective. A study of the links between pollen concentrations and meteorological data constitutes the last section of this third part.
