2. Identifying the shingles transmission period

If a person has shingles, the active infection can last a long time, but they won't be contagious for that entire period. They can only infect a person who has never had the virus when there are blisters on their skin.

In the early stages of shingles, an infected person will begin to feel pain, but will not yet have blisters and is therefore not contagious. Likewise, when the disease is nearly gone, the blisters will have scabbed over completely and are not contagious.
