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.

In brief

The first birch pollen grains are measured, but this is so far mainly due to importation from abroad. People should be alert because the flowering of birches in Belgium is very near. People sensitive to these trees should already take all the necessary precautions.

 

Other trees currently in bloom include ash, elm, willow, poplar and some members of the Cupressaceae family.
