In brief

The pollen season for hazel (Corylus) and alder (Alnus) is beginning. In recent days, airborne pollen concentrations have started to increase. People sensitized to Betulaceae pollen are advised to take extra precautions, as the risk of allergic reactions will rapidly rise from now on and remain high over the coming weeks.

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.
