Introduction
​

IAS® Allergies can be used to analyse the level of allergic diseases in France on a daily basis. It is particularly well suited to monitoring the spatial and temporal evolution of seasonal allergies. From cypress in February to ragweed in August, it allows you to see how allergic diseases develop on D+1 and throughout the year. The model used by IAS® Allergies is based on the monitoring of a set of drugs indicated in the symptomatic treatment of allergies in France, and uses the analysis and representation methods developed by OpenHealth.The information is available in the form of maps showing yesterday's situation and the progression of seasonal allergies in France over the last 30 days. The size of each geographical area is proportional to its number of inhabitants (Ile-de-France is therefore very large, representation 7). The colour becomes darker as the allergy increases. An Allergies index (box on the right of the map) of 100 means that there are no seasonal allergies (the basic level of allergies in France); an Allergies index of 140 means that there are 40% more allergies than the basic level.
