Chickenpox is an acute respiratory infection caused by the first infection with varicella-zoster virus, which starts with a rash on the head and face and spreads rapidly throughout the body, accompanied by fever, itching and depression. Early treatment with antiviral drugs such as acyclovir is needed to avoid aggravation of the disease and complications such as encephalitis and pneumonia. If the herpes is not completely dry, scabbed and peeled off, you should not scratch it with your hands to prevent it from breaking down and becoming infected and leaving scars. If the itching is obvious, you can use stove glycolic lotion rubbing to stop itching, and if necessary, you can take anti-allergy drugs such as oral loratadine. If the patient has a fever, the head can be cooled physically with an ice pack, and those with high fever should be treated with antipyretic drugs as prescribed by the doctor. During the onset of chickenpox, care should be taken to take the necessary isolation measures to avoid transmission to others.
