The typical clinical manifestation of chickenpox is a rash and it can be accompanied by itching. In the early stages of chickenpox, if the patient is an adolescent or adult, there are obvious systemic symptoms, which can be accompanied by fever and other uncomfortable manifestations 1-2 days prior to the appearance of the rash. It can also be accompanied by sneezing, runny nose, sore throat or cough, and fever sometimes accompanied by fear of cold, headache and sweating. However, in younger children or adults with less severe symptoms, it is likely that the fever will not appear, or it will appear only at the same time as the rash. The rash is often not detected in time when it first appears, but it is first felt itchy, and only after feeling significant itching that the area is found to have a red papule, while sometimes a herpes can already be detected. Therefore, in the early stages of chickenpox, it is mainly a red papule and a herpetic rash, and it appears mainly on the trunk area in a relatively small amount.
