In brief

The pollen seasons of grasses and mugwort (Artemisia) have now ended. A few grains may still be detected sporadically, mainly due to resuspension by the wind, but their active emission period is over.

In addition, summer weather conditions are favourable to the development of certain allergenic moulds. Spore concentrations of the genus Cladosporium remain 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.
