Ringworm is a disease that has become more common in recent years in both humans and animals. Ringworm is transmitted from cats to humans as a result of close contact with cats after people have pet cats, which leads to infection with ringworm bacteria. The main manifestation is the appearance of ring-like red patches on the body, with tiny papules at the edges of the red patches and intense itching. Ringworm itself in this case is also self-infectious, leading to an increase in the number of lesions, so it is important to treat it early. On the one hand, cats should be taken to a veterinary hospital for treatment, and human cat moss should also be addressed early under the guidance of a specialist in a timely manner.
