People with ringworm usually get better in about 15-20 days with regular treatment. Ringworm is a fungal infection that occurs when human skin comes into contact with a cat and is infected by a fungus carried by the cat, resulting in an itchy localized skin condition. It usually forms a circular patch on the surface of the skin with raised papules around the edges that gradually get better in the middle and gradually expand outward, with scattered flakes on the surface. It can be treated with some antifungal topical medications under the guidance of a doctor, which can effectively remove the fungus. Usually after 15-20 days of treatment, the ringworm that has formed can gradually fade away and return to a healthy skin condition. While treating ringworm in humans, it is recommended to treat ringworm on cats at the same time to avoid being infected by it again. It is also important to use a full course of medication to avoid recurring attacks.
