When chickenpox is well, for the vast majority of patients, it is the disappearance of all symptoms. First of all, the fever will disappear, usually in the first 4-5 days of chickenpox, and by the time the chickenpox rash is almost completely crusted over, the body temperature will not rise again. The patient with chickenpox may also have headache and fear of cold, which are mostly accompanying symptoms of fever in chickenpox patients and will disappear with the fever. The skin rash of chickenpox patients is usually not deeply damaged, so after the crusts have receded, the skin is usually intact and does not leave scars, nor does it lead to hyperpigmentation or flaking. Patients with chickenpox who develop secondary bacterial infections and whose scabs are rubbed off when they are not fully healed may be left with scarring or hyperpigmentation. If chickenpox has a corresponding complication, pneumonia, when the rash of chickenpox is completely healed, there is a possibility that coughing and coughing may still be present. If chickenpox is accompanied by chickenpox encephalitis, this condition may last longer.
