In brief

The grass pollen season has now come to an end. A few grains may still be detected sporadically, mainly due to resuspension by the wind, but the active emission period is over. Pollen concentrations remain well below the allergic threshold of 50 grains/m³, and this trend is expected to continue. People allergic to grass pollen should therefore experience lasting relief from their symptoms.

The mugwort (Artemisia) pollen season has started. These pollen grains are also allergenic and can trigger reactions in sensitised individuals, who should remain vigilant.

In addition, summer weather conditions are favourable to the development of certain allergenic moulds. Spore concentrations of the Cladosporium and Alternaria genera are currently very high. These spores are among the most common outdoor allergens in summer and can cause respiratory symptoms in sensitive individuals.

Good to know

  • A few useful recommendations: avoid outdoor activities, wear sun glasses, do not dry linen outside, rinse your nose regularly, wash your hair before going to sleep.

  • Typical allergy symptoms such as runny nose, cough or shortness of breath (in case of asthma) can easily be mistaken for a cold, flu or coronavirus infection. However, fever and body aches should be given special attention as they might be caused by viral infection. It is recommended to call your general practitioner in case of doubt.

  • The standardized pollen detection technique allows retrospective measurement of the levels from samples taken the day before. Samples are analyzed manually during the working days by optical microscopy.
