Chickenpox is an acute infectious disease caused by varicella-zoster virus infection, with an incubation period of 10-21 days, averaging 14 days. The incubation period of chickenpox is generally asymptomatic, with fever predominating in the early stages, followed by a rapid onset of rash in 1-2 days, with the rash rapidly forming clear, transparent blisters in about 6 hours, scattered over all parts of the body. During the rash period of 1-6 days, the rash appears in batches and gradually crusts over and falls off. The duration of chickenpox is usually about 10 days, and the whole process is contagious, so the necessary isolation measures must be done during this period. In addition, in the acute phase of chicken pox, if the symptoms are more serious, you should go to the hospital dermatology or infectious disease department as soon as possible, and apply antiviral drugs, such as valacyclovir or acyclovir, as prescribed by the doctor. The patient with chicken pox should pay attention to the fact that before the blisters are completely dry and scabbed, they must avoid scratching to avoid scarring due to infection and affecting the beauty.
