The symptoms are different in the three stages of the disease. 1. the first stage is the infection stage: it is also the skin breakdown stage, which is not allowed to take a bath, and the first one is easily infected locally after bathing. 2. it is easy for the infection to spread to other parts of the body. 3. after the infection spreads to other parts of the body, other parts of the body are also easily infected, so this kind of patient cannot take a bath. In the middle and late stages or the sequelae period, bathing is possible, but you must follow the doctor’s instructions and listen to the doctor’s instructions to operate.
