Throughout the first year, you start by learning about nail anatomy in the first semester, then move onto nail pathologies, which include a wide range of diseases, syndromes, and/or conditions that can contribute to certain nail looks and deformities of the nail, in the second semester. Nail fungus probably covers about a quarter of the nail pathology section. You learn about common causes, risk factors, and treatments. In my opinion, we learn a lot about testing for fungus and how to treat it. Hope that helps 🙂
