Why is it more difficult to treat fungal infections than bacterial infections in humans?

The answer is simple. Fungi are much more difficult to eliminate than bacteria because of their ability to penetrate deep into the body and create a biofilm, releasing toxins that can be harmful for humans. They also develop resistance through mutations in genes over time when exposed to antibiotics like penicillin or amoxicillin. This means they require stronger medications such as ketoconazole or itraconazole, which have some unpleasant side effects including liver damage if taken long-term without medical supervision.
