Chickenpox is not the same as shingles. Chickenpox is an incipient infection caused by varicella zoster. Early manifestations are mainly chills, fever, and blisters extending from the face to the trunk, with thin, easily broken edges. As the age increases, clinical findings show that younger patients have milder symptoms and older patients have more severe varicella symptoms. Chickenpox can also be complicated by encephalitis or pneumonia, while herpes zoster is mainly a limited cluster of papules with more pronounced pain and can also be accompanied by fever. Both of these are treated with the same medication, vaxilovir. Patients with immunocompromised, generalized herpes zoster, which can have varicella-like manifestations, are found clinically to have underlying disease in this area. With organ transplantation or the use of targeted drugs, or oncologic chemotherapy, patients can have chickenpox-like manifestations.
