yes the virus that causes the common wart can spread fromt he fingers to the lips or even the inside of the nose (guess how this may have happened). the tape is a good idea but why not just treat the wart? a few seconds of freezing it with liquid nitrogen may do it or it could take a few treatments (depending on the location the size of the wart and your daughter's cooperation - this can sting). there are other slower but less-painful methods as well. if you treat the wart on the finger then the chance of it spreading is very unlikely.
can a child spread warts from their fingers to their mouth? . my daughter has a wart on her finger that she sucks on and i am afraid it will spread to her mouth. we are scared to put treatment on it because she sucks on her fingers. so we put medical tape around her finger which is what her dr. recommended.
