Chickenpox takes about 10 days to heal. In about 10 days, the symptoms of chickenpox can be manifested as a fever and a rash, which starts as a maculopapular rash and breaks down into a herpetic rash, after which a blood scab will form and the scab will slowly fall off for about 10 days. However, it should be judged according to each person’s condition whether it is more than 10 days or less than 10 days, because the rash of chickenpox has more or less, for less likely to stop occurring new rash in 2-3 days, when the existing rash begins to crust, the crust may fall off completely in less than 10 days. For those who have more rashes, it is likely that new chickenpox will still appear on the 4th, 5th, or even 6th day, and then the scab will be slower, and it may take more than 10 days for the chickenpox scab to fall off completely.
