In brief

The pollen season of hazel (Corylus) and alder (Alnus) is gradually coming to an end. Their concentrations remain moderate in some areas but are generally decreasing. At the same time, the very first birch (Betula) pollen grains have been detected, signalling the start of this season, which is particularly significant for people sensitive to birch pollen.

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.
