The Centers for Disease Control and Prevention (CDC) has issued a warning about a dangerous fungus, Candida auris, which has seen a "dramatic increase" in cases and is spreading rapidly through health care facilities in the US. The CDC has classified the fungal infection as an "urgent threat" because it is becoming resistant to antifungal drugs, is multidrug-resistant, easily spreads through healthcare facilities, and can cause deadly disease. Scientists found 4,041 people who carried the fungus in 2021 but were not sick at the time. The fungus can be found on the skin and throughout the body, and about 30-60% of infected people have died.
