I would imagine if your humidity is always high (99%), you can get fungus build up. My female veiled, after mating, had some small punctures from my males extremely sharp nails. From so much humidity she got a skin fungus, but after I cut down on the misting (just once a day, but kept the dripper for drinking), the fungus dried up and it is all healed up. probably another shed or two and there should be no sign of it at all.
