Candida auris is a type of fungus that can cause serious infections in humans, particularly in those with weakened immune systems. It was first identified in 2009 and has since emerged as a global health threat due to its resistance to multiple antifungal medications. This fungus can spread in healthcare settings, making it a concern for hospitals and nursing homes. Infections can lead to severe complications, especially in patients with underlying health conditions. Proper hygiene and infection control measures are essential to prevent its spread.
