The red marks that appear after the scabs fall off can recover in a few days, depending on the sensitivity of the patient’s own skin and self-recovery function, and there is no specific time period in the clinic. At the end of the disease, the scab will gradually fall off and leave a red mark, which is a normal repair process of the body. However, if the scab is forcibly torn away by hand when the chickenpox is scabbed, it will cause local bleeding and even scarring or leave pockmarks, which will take a relatively long time to repair, or even need to rely on medical aesthetic treatment. Chickenpox is a contagious disease and is contagious during the first two days until the blisters dry and the scabs form. During this period, you must take good isolation measures and reduce unnecessary outings to avoid infecting others.
