Grass pollen in the air is decreasing but moderate amounts are still present and hay fever sufferers will still be experiencing symptoms. Tree pollen is diminishing and weed pollen remains low. Fungal spores (mould) increased in the last week due to slight rain and moderate temperatures. Increases were seen for Alternaria, Cladosporium and Epicoccum. Alternaria concentrations were high for most of the week. Alternaria is the most allergenic aeroallergen in the Western Cape.
