Chickenpox can be completely out within 1-2 weeks, and the rash can be seen in the course of the disease with simultaneous macules, papules, herpes and crusted rash, as well as in the mucous membranes of the mouth, pharynx and vulva. The rash first occurs on the trunk and head, gradually expanding to the face and finally the extremities. The rash is usually more frequent on the trunk and less frequent on the extremities and face, with a centripetal distribution. The rash starts as a pinkish blotchy rash, which turns into a papule after a few hours, and then into a herpes after a few hours, with a ring of redness at the base of the herpes. Chickenpox can be preceded by malaise, anorexia, chills and other general discomfort, which can last 1-2 days before the rash appears. Chickenpox can have serious complications, such as encephalitis.
