Candidiasis, a fungal infection, occurs due to the yeast Candida. While there are several species of Candida, Candida albicans is one of the most common ones that can cause infections in humans.

However, if the immune system is weakened or the body's natural balance is disrupted, C. albicans can turn harmful, leading to infections . This yeast is a frequent culprit in hospital-acquired infections and has the ability to infect almost any part of the body . It can affect everything from the brain and spinal cord to the muscles, joints, kidneys, eyes, and other organs, depending on the site of infection. The symptoms vary based on the area that's infected .
