Chickenpox does not usually grow in batches, but there is a sequence. Chickenpox is caused by varicella-zoster virus infection, usually with fever for 1~2 days, after the fever goes down, there will be a rash. The rash occurs on the trunk and head first, then gradually spreads to the face, and finally to the limbs. Generally, the rash is more frequent on the trunk and trunk, less frequent on the limbs and face, and most of them are centripetal in distribution. The rash starts out as a pinkish-red blotchy rash, which then turns into a papule, and then turns into herpes, which is filled with fluid, within a few hours. Most cases of chickenpox heal within 1 to 2 weeks, when the blisters dry up, scab over, and fall off without leaving a mark. However, there are some patients with weakened immune systems that last longer, and some may develop severe chickenpox, which manifests as herpetic or hemorrhagic chickenpox. If the diagnosis of chickenpox is confirmed and unusual symptoms, such as recurrent fever, are present, you should seek prompt medical attention and standardized treatment to minimize the adverse effects of the disease.
