How many days does herpes zoster spread?

Herpes zoster, also known as chickenpox or shingles, is contagious and lasts from the day before the rash appears to the day when the disease is cured. It is usually a cluster of varicella or shingles along the nerves, often accompanied by severe pain, usually on the head and one side of the chest. The early symptoms of shingles are pain in the affected area, and after a week of pain, the skin will show blisters of varying sizes. During this period, shingles is contagious. Herpes zoster is mainly transmitted through the respiratory tract, so the patient should be isolated from the respiratory tract to prevent infection to others. At the same time, patients with herpes zoster should eat a light diet and should not eat spicy and greasy food.
