What is it about?

The relationship between hay fever symptoms and Poaceae is not consistently linear and reaches a plateau. At the beginning of the season (0<Poaceae<10 grains/m3), a priming and a pre-priming phenomena are observed, without any threshold.

Why is it important?

It may be important to begin the symptomatic treatment in hay fever Poaceae sufferers as soon as the pollination season begins (above 1 Poaceae grain), especially for those with perennial sensitization.
