Allergy: pollens, the great return

With the lenient temperatures of February, pollens are already of return. According to the Pollinic Allergo bulletin published by the inspection Network of pollens, vigilance is essential at this beginning of March because the production and especially the dispersion of pollens of tree are high, involving important allergic risks, particularly in Mediterranean region and in the Midday-Pyrenees.

The higher temperatures with the seasonal normals precipitated the production of pollens of tree, which already start to disperse in all France. If the allergic risk of exposure to pollens is already very high in the Mediterranean zone and of the Midday-Pyrenees, the other areas are not saved. The alder and the cypress seriously start to attack the sensitive people. Pollens of hazel tree, ash and poplar follow closely. The point on the pollinic situation according to the last Pollinic Allergo bulletin of the Domestic network of aerobiologic monitoring (Rnsa).
