In brief

The alder and hazel pollen season is nearly coming to an end, but birch pollen is now on the rise, with concentrations increasing significantly in recent days. People allergic to Betulaceae pollens should remain vigilant and continue taking precautions as the risk increases.

Meanwhile, other trees have also started blooming, such as ashes, hornbeams, poplars, willows, elms, and cypresses.

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.
