<unk>  is caused by a tiny fungus known as dermatophyte. These tiny organisms normally live on the superficial skin surface, and when the opportunity is right, they can induce a rash or infection. The disease can also be acquired by person-to-person transfer usually via direct skin contact with an infected individual. Animal-to-human transmission is also common. Ringworm commonly occurs on pets (dogs, cats) and the fungus can be acquired while petting or grooming an animal. Ringworm can also be acquired from other animals such as horses, pigs, ferrets and cows. The fungus can also be spread by touching inanimate objects like personal care products, bed linen, combs, athletic gear, or hair brushes contaminated by an affected person. Individuals at high risk of acquiring ringworm include those who: * Live in crowded, humid conditions. * Sweat excessively, as sweat can produce a humid wet environment where the pathogenic fungi can thrive. This is most common in the armpits, groin creases and skin folds of the abdomen. * Participate in close contact sports like soccer, rugby, or wrestling. * Wear tight, constrictive clothing with poor aeration. * Have a weakened immune system (e.g., those infected with HIV or taking immunosuppressive drugs).
