Jing Jing, a 6-year-old girl who lives in Jiangdong District, is particularly fond of a puppy she keeps and often holds it in her arms to play with. However, recently Jingjing always felt itchy and had a lot of “dandruff” on her head. Even Jingjing’s mother also had some red bumps on her body. So mother and daughter came to our hospital together. After some detailed questioning and examination, it was confirmed that both mother and daughter were suffering from ringworm. There are many different kinds of fungi that cause ringworm, and depending on their habits, they are classified as familial, animal-friendly, and soil-friendly. By relatives, we mean that these fungi mainly colonize and cause disease on the human body and cause relatively minor skin damage from ringworm, while pro-animal fungi grow and spread mainly on animals such as dogs, cats and sheep, and once these fungi are transmitted to the human body, they can cause more serious dermatophytosis such as erythema, papules, blisters, pustules, etc., and in severe cases, they can also cause generalized fever and joint aches and pains. As the weather turns hotter, more parts of people’s bodies become exposed. In dermatology clinics, there has been a significant increase in the number of cases of skin diseases caused by close contact with animals. In addition to fungus, pets have many parasites, such as fleas, which can cause skin diseases such as insect bite dermatitis when healthy skin comes in contact with pathogenic bodies. Because the skin of pets is easily contaminated by dust, dirt, dead hair and skin excrement, it becomes an easy breeding ground for parasites such as fleas, and people are susceptible to infection after direct contact with animals. If you are an allergic person, you will also experience papular urticaria and itching all over your body. Nowadays, more and more families have pets, and although pet ownership can reflect human concern for animals, it can cause harm if not managed properly. Therefore, parents are advised not to let their children get too close to their pets. To keep indoor air circulation, pay attention to keep the personal hygiene of children, and pets must wash their hands after playing. The pet’s nest should be cleaned frequently, sunbathed, and the pet should be bathed frequently, and the pet should be observed for itching symptoms such as clawing and rolling on the ground. Pets with ringworm or parasites should be isolated and treated promptly, never send them away, as this can spread the disease among animals and people. Those who already have ringworm infection in the home need to be seen in a timely manner, otherwise it will not only aggravate their own disease, but may also spread among family members or infect colleagues or classmates.
