Shingles, a viral infection of the nerve roots caused by the chickenpox virus, can sometimes lead to a painful complication called post-herpetic neuralgia. Sometimes, a physical stress like cold or sunburn can bring on an attack. Even clothing touching the skin or a cool breeze can cause excruciating pain.
However, if you have had chickenpox (or shingles), you cannot get shingles from coming in contact with someone who is having an active outbreak of shingles. A shingles outbreak is triggered from within your own body.t is not caused by contact with someone else. So, to answer your question, you do not need to avoid contact with your dad. You also should be aware that you can get the shingles vaccination if you're over age 50, even if you've had an outbreak of shingles in the past.
