As a dermatosis caused by fungi, tinea cruris is highly contagious. Children, pregnant women, the elderly and other people with low immunity, once exposed to this fungus, the possibility of infection is very high, so once tinea cruris is found, it is necessary to take medicine quickly.
Avoid close contact with patients with tinea cruris, and do not use daily necessities or toiletries, such as sheets and towels. When going out to stay in some hotels with poor sanitation and disinfection, try to use bedding to reduce the chance of bacterial infection, especially for some people with low immunity.
It is a long process to treat tinea cruris, especially intractable tinea cruris. It is necessary to use the "Xianda Jing" for external use. I hope you can treat it correctly and get well soon!
