Even though many studies tested and found Hawan altering biome by killing pathogenic bacteria, fungus, and viruses. Studies are required to further validate its effect on load of viruses, its infectivity and if it can reduce occurrence of flu-like illnesses and their complications. In view of SARS-CoV-2 pandemic and its potential of community spread, one of the measure to curtail community spread may be Indian traditional mass fumigation technique of Hawan, which is considered as cultural practice for health and well being by offering ingredients of medicinal values in to fire. Such processing of specific ingredients through fire is considered turning them to nano-particles and act to alter biome. This paper reviews existing research evidences and suggests future mode of studies on viruses. This also highlights dearth of research capacity for estimation of virus content from the open air samples and the need to strengthen it through potential/ proposed technologies
