Chickenpox is caused by infection with the varicella-zoster virus. The clinical manifestations of chickenpox are generalized papules, blisters and crusts, so chickenpox can also grow on the skin of the head. Chickenpox can occur on all parts of the body, but often occurs mainly on the chest and neck, and in some patients, on the scalp. If chickenpox appears on the scalp, do not scratch the area to avoid secondary infection caused by the rupture of the herpes. If the herpes is infected with redness, swelling or pus, anti-inflammatory creams can be applied. Do not wash your hair for the time being until the herpes is completely dry, crusted and peeling. If the symptoms of chickenpox are severe and accompanied by fever, headache, nausea or poor appetite and poor mental status, you should consult the respiratory department of an infectious disease hospital early for active treatment. Patients should pay attention to isolation during the onset of chickenpox to avoid infecting others, and at the same time, patients should pay attention to warmth, avoid getting cold, rest and reasonable diet to avoid complications.
