<s>[INST] I have been remodeling my bathroom (home build in the 50s) and found mold underneath the ceramic tile.  I did spray the moldy underlayment with mold killer until we can replace it, but recently found out I now have impetigo and cellulitis.  I did have a couple cuts from removing the tile.  Is it possible this mold is still airborne and caused the infection? [/INST] Hi, Welcome to Chat Doctor. There are chances of fungi causing subcutaneous infection, where the fungi are introduced into the skin through thorn prick or minor injury. But impetigo and cellulitis is most commonly caused by bacteria. I suggest you get a pus sample from the wound and test for bacterial as well as fungal culture. Subcutaneous infections of the skin are most commonly caused by colored fungi called dematacious fungi which are molds. Thanks </s>
