Adults can also get chickenpox. Chickenpox is caused by a varicella-zoster virus infection, and adults who have not been previously infected with the virus can get chickenpox, which is characterized by papules and other skin lesions. The varicella-zoster virus can cause either chickenpox or shingles, and its primary infection usually manifests as chickenpox. Adults who have not been previously infected with the varicella-zoster virus may present with chickenpox after the initial infection. Chickenpox lesions usually appear first on the head and face, expanding to the trunk and proximal extremities as the disease progresses. The lesions are red macules, papules, blisters, and pustules, which gradually crust over and fall off. At the same time, it may be accompanied by fever, headache, fatigue and other symptoms. If there is any discomfort, it is recommended to consult a doctor in time for diagnosis and treatment.
