New app AirAllergy

AirAllergy launches its new mobile app! Follow pollen levels in real time, consult daily readings and RMI forecast maps for the coming days.

In brief

The birch (Betula) pollen season is currently at its peak. Airborne pollen concentrations, and consequently the risk of allergic reactions for sensitized individuals, are very high. Only periods of rainfall can temporarily reduce pollen levels. People with allergies are therefore advised to take all necessary precautions and follow their doctor’s recommendations.

 

Due to the ongoing strike at Bpost, the transport of samples is experiencing delays. As a result, the publication of results may be postponed. The results will be published as soon as the affected samples have been received and analyzed. Thank you for your understanding.

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.
