Tinea capitis is an extremely common fungal skin disease that occurs on the hands and feet (note: a fungal skin infection that occurs alone on the back of the hands or feet is called tinea corporis). Tinea pedis, however, is more common than tinea cruris. 1. The disease has a tendency to be contagious. The fungus is extremely vital and can survive and remain virulent for more than a year even when it is separated from living hair, nails, dander, etc. Therefore, the dander shed by a patient with tinea capitis is a vector of infection. 2. Ringworm can cause a rash to appear on the skin outside of the lesion. The fungal antigens released from active ringworm lesions are carried to the skin via the bloodstream and trigger a metaplastic rash. 3. Tinea capitis can also cause sepsis. If left untreated, ringworm can spread to other parts of the body and cause ringworm, ringworm of the femur, ringworm of the nail, and secondary bacterial infections that can lead to lymphangitis, lymphadenitis, and even sepsis. It can also cause lymphadenitis and lymph node infection, and even sepsis. 4. This is especially true for tinea cruris, which can cause additional problems for the patient’s normal social life. The above-mentioned points remind us that we must pay attention to the prevention and treatment of tinea capitis, and that strengthening its prevention and treatment can effectively alleviate the pain of patients and make them recover soon. The following are some of the things that patients should do at home to prevent infection. Wear breathable shoes and socks to keep your feet dry; people who are prone to foot sweat should wear cotton socks, not breathable nylon socks or rubber shoes, and should develop good hygiene habits, wash their feet every day, change their socks regularly, and keep their shoes and socks dry. 2.Prevent infection. Pay attention to personal hygiene and public hygiene. In daily life, be careful not to wear other people’s shoes and socks, and to use the footwash basin for one person only; when washing socks of people with tinea pedis, try to separate them from other clothes, and preferably scald them with boiling water or expose them to sunlight; avoid bathing and swimming in unclean baths and swimming pools; do not walk barefoot in public pools, baths, gyms, etc.; avoid using public scissors and nail clippers to cut diseased nails. 3.Actively treat. The key is to actively treat the primary active ringworm lesion. Ringworm is complicated to treat, and there are no uniform rules about which drugs to choose for different types, stages, or even individuals; in addition, different individuals have different sweating conditions and susceptibility to ringworm. Therefore, patients with ringworm must visit a dermatologist at a regular hospital and receive regular treatment and reasonable medication under the guidance of a dermatologist.
