In brief
The allergenic pollen season is now over in Belgium. Monitoring will resume in early January, when the hazel trees are expected to flower.
Although pollen no longer poses a significant risk at this time of year, vigilance is still advised for people who are sensitive to spores, particularly those of the mould Cladosporium or basidiospores released by mushrooms. With the arrival of autumn and the fact that we spend more time indoors, exposure to house dust allergens also warrants special attention. House dust mites, mould in damp or poorly ventilated homes, and pet allergens can cause or perpetuate symptoms of rhinitis, conjunctivitis or asthma, even when no airborne allergens are present in the outdoor air.
