Hello - I believe that adult chickenpox is making its way around my community, and I m able to smell a peculiar odor on individuals who are coming down with it. The scent occurs 3 - 5 days before the onset of major symptoms. It can perhaps be best described as slightly sulphuric, murky, loamy. It is organic rather than, for example, an RNA style virus, such as enterovirus. Have you heard of anyone being able to smell viruses before? Not sure what to do with this ability.
