What is a key function of systemic fungal infections?

Systemic fungal infections are characterized by their ability to infect deeper tissues or organs rather than being limited to superficial layers of the skin. These infections can disseminate throughout the body, affecting vital organs such as the lungs, brain, or bloodstream. They are generally more serious and can lead to significant health complications, especially if not diagnosed and treated promptly.

Additionally, while some fungal infections can promote immune deficiency or primarily affect immunocompromised individuals, systemic infections are not restricted to these populations. They can be found in healthy individuals under certain circumstances, and the severity of the infection often depends on the specific fungal pathogen involved and the host's immune response.
