After the symptoms of chickenpox blisters appear, it is not recommended to artificially pick them to avoid infection, usually 1-3 days after the herpes begins to crust, about 10 days to heal and disappear. Chickenpox is a viral infectious disease that is spread mainly through respiratory droplets and direct contact, and has an acute onset. The first is a pinpoint red rash, which quickly turns into a papule, and after a few hours can turn into a green bean sized blister with a slight depression in the middle, and the walls of the blister are very thin and easy to rub through. 1-3 days later it can dry and crust over, and then heal and disappear in about 10 days. The complications of chickenpox are rare, but occasionally serious complications are seen, such as chickenpox pneumonia, chickenpox myocarditis, chickenpox encephalitis, etc. The patient should be isolated for treatment and avoid going to crowded places to avoid infecting others with chicken pox on the one hand, and the patient’s own resistance is low during the illness on the other hand, to avoid other people from infecting themselves with other diseases. During the rash, it is not advisable to take a bath, as the blisters may break and cause local rash infection. In addition, when the blisters itch, they should not be scratched, especially on the face, which can easily leave depressed scars after scratching. What’s more, you can’t pick it with a needle, which may cause local or systemic skin infections and aggravate the condition.
