Here is what I know, I caught CP at 40 years old from my daughter. You do not want CP. It is very dangerous for old pharts. Especially if it hits your privates. Doctor said it doesn't affect kids much, but, adults can die from the stuff.
Also what I was told is you can not get shingles if you haven't had CP' The virus is the same, but, shingles is a flair up of CP as it stays in your body near the nerves
Copied from Mayo:
Shingles is caused by the varicella-zoster virus — the same virus that causes chickenpox. After you've had chickenpox, the virus lies inactive in nerve tissue near your spinal cord and brain. Years later, the virus may reactivate as shingles.
So you can not get shingles without having an earlier case of CP.
Believe me CP is nothing to mess around as an old phart.And for you guys that have never CP. Get A Vaccine!
