The aerial fungal spores play an important role in causing seasonal allergies and other respiratory diseases in human beings. The presence fungal spores belonging to genera Alternaria, Aspergillus, Candida, Cladosporium, Dematium, Helminthosporium, Mucor, Rhizopus, Trichoderma and Penicilliumin air with high concentration may cause mycotic infections. It has been observed that the fungal spores showed seasonal variations and their concentration change with climatic parameters. The qualitative and quantitative analysis of fungal aeroallergens especially their composition at a particular public place may help to evaluate the status of public health. The composition of fungal aeroallergens reveal the future threats of fungal allergies and asthma in indoor and outdoor environments. The respirable concentration of aerial fungal spores is very important as it may be hazards in children and old age persons. The monitoring of fungal spores in seasonal changes may help to construct an epidemiological colander for local population and to avoid fungal allergies. After COVID-19 the drastic increase in respiratory diseases has been reported therefore the study of aerial fungal spores may be significant to control allergies in future.
