Could this cause a fungal infection?
If you had a fungal infection on your finger and you scratched a cut, could the fungal infection spread to the cut? Can you get fungal infections inside your body or are they just external? Can fungal infections be as serious as bacterial and viral infections in an otherwise healthy person?

It could possibly happen. You can go to a good health food store that knows what they are talknig about to get something to kill the fungus from the inside out instead of taking a prescribed medicine that can easily harm your liver.
