In addition to the pollen sensors installed in the four corners of France, the profession has had a new tool for fifteen years to prevent this allergy. These are sentinel pollen plants that have appeared in many cities, especially in the Great West.

The alerts also allow him to put together a very accurate pollen calendar each year, which helps him determine what allergies patients have. “It’s often very complicated because the pollen is overlapping,” he says. But depending on when the first symptoms appeared, we can identify the types that are most likely to cause the allergy.”
