In brief

The grass pollen season has begun. People who are allergic to this pollen type should take all necessary precautions, as pollen concentrations are expected to gradually increase over the coming weeks.

Oak pollination is still in full swing. Exceptionally high levels have been recorded in recent days. Although oak pollen allergy is less common, sensitized individuals may experience a significant resurgence of symptoms.

Other trees are still in bloom, such as plane trees, beeches, horse chestnuts, and certain trees from the pine family.

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.
