Causes of tinea corporis in children
The fungus that causes tinea corporis in children is mainly microsporum canis, which is often parasitic on animals, especially cats and dogs. Therefore, when children play with kittens and puppies suffering from tinea, the fungus can be inoculated on the skin of susceptible children to cause tinea corporis. In recent years, 70%-80% of children's tinea corporis occurs on the face, and parents can often provide close contact with kittens and puppies. Since the late 1980s, with the improvement of people's living standards, the number of families with pets has gradually increased, and small pets have more often become children's children. Since kittens and puppies can infect tinea corporis, we should be extra cautious in raising small animals at home. The doctor's advice is that captive puppies and kittens should go to the pet hospital regularly for examination, and the tinea corporis should be isolated and treated in time to avoid being passed on to children at home. In addition, it is worth reminding that hair loss on kittens and puppies is often a sign of tinea corporis, which should attract parents' attention. Children who are suspected of having tinea corporis should go to the hospital dermatology department with mycological examination in time to avoid misdiagnosis, and don't treat themselves with drugs casually to avoid refractory tinea corporis.
