Allergy to pollen and grasses: the 2015 season begins

The early spring accelerates the production of pollen, especially in the South and West of France. The National Network Aerobiological surveillance (RNSA) announces the first occurrence of allergies, combined with the effects of pollution.

The anticyclone installed in the country is causing mild temperatures but also early allergic risks. The map developed by the National Network Aerobiological surveillance (RNSA) is telling: pollens already spread throughout the South and West of France, but not only.

  • The cypress pollens are particularly concentrated in the South of France; the allergic risk today is maximum on the Mediterranean coast. They are found throughout the country in smaller quantities. The risk is low to medium locally.
  • In the West, the willows and grasses already produce their pollens.
  • In the North, hazel finished flowering. Their pollen is fortunately low allergenicity.
  • Throughout the territory, the alder, the ash and poplar take over with equally low impact in terms of allergies.

But beware: “More than pollen each separately, are mixtures that allergic should fear,” the alert RNSA.
