In brief

There is almost no more pollen in the air.

Cladosporium mold spore concentrations may still vary depending on weather conditions.

The next wave expected in the coming weeks is that of spores emitted by mushrooms from meadows and woods (basidiospores). Some of them could be responsible for respiratory allergies.

Good to know

  • 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.

 

  • From the end of the pollen season (early September), the results for Brussels are updated 3x a week. The update frequency remains weekly for the other stations.

 

  • 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.
