Avis et rapport de l'Anses relatif à l'impact sanitaire et coûts associés de l'ambroisie à feuilles d'armoise en France

Abstract : As underlined in a previous ANSES publication (ANSES 2014), common ragweed1releases a highly allergenic pollen that can easily travel long distances and is thus a major public health challenge. Widespread in Hungaryand in northern Italy, ragweed is also found in the Rhône Valley in France. Recent maps have shown wider spread of the plantin France over the past few years. The health impact of ragweed is regularly assessed in Auvergne-Rhône-Alpes, the most affected region of France, by the Regional Health Agency (ARS) and the Regional Health Observatory (ORS). According to a telephone survey of the general public, the prevalence of ragweed allergy was estimated at 12.5% to 14.1% in this region and has been increasing since 2004 (Anzivino, Marant-Micallef, andSonko 2014). High spatial disparities have been observed. Expenditure associated with this allergy (including use of medication, consultations and sick leave) was estimated at €8.9 to €13.2 million in 2014 in the Rhône-Alpes region (Gelas 2015). However, the health and economic impact of ragweed still needs to be assessed inthe rest of France (outside of Auvergne-Rhône-Alpes).The Third National Environmental Health Action Plan (2015-2019) provides for measures for the monitoring and assessment of ragweed in France, but with no legal framework. Decree no. 2017-645 of 26 April 2017 defines measures intended to prevent the appearance of ragweed or limit its spread; their implementation is placed under the responsibility of prefects after opinions issued by the ARS and the Departmental Council for the Environment and Health and Technological Risks (CODERST). In this context, the Directorate General for Health submitted a formal request to ANSES on 5 April 2018 to: - Document the prevalence of common ragweed allergy and its changes in recent years in France and abroad based onthe level of exposure to ragweed pollen and the level of infestation. - Identify potential mechanisms and factors associated with differentiated changes in this prevalence. These may include intrinsic factors related to the plant (local spread) and extrinsic factors related to human activity and climate change possibly favouring the spread of ragweed. - Estimate the prevalence of ragweed allergy across France and how it may develop based on proposed scenarios of changes in the state of infestation. A distribution by département will be investigated. - Assess the cost of ragweed allergy across France and how it may change taking the same change scenarios into account. A distribution of these costs by départementwill be investigated. The impacts of ragweed vary in nature. In light of the objectives set, this appraisal focused on the health impact and ultimately the costs associated with this impact. However, data are also given for informational purposes to drive reflections concerning the agri-environmental impacts.
