A
Chicken pox:lysogenic Shingles:lytic
B
Chicken pox:lytic Shingles:Lysogenic
C
Chicken pox:parasitic Shingles:reemergence parasitic
D
Chicken pox:parasitic Shingles:bacterial
Explanation: 

Detailed explanation-1: -The varicella-zoster virus also causes shingles. After chickenpox, the virus remains in the body (dormant). People get shingles when VZV reactivates in their bodies after they have already had chickenpox.

Detailed explanation-2: -Most people who have had chickenpox will be immune to the disease for the rest of their lives. However, the virus remains inactive in nerve tissue and may reactivate later in life causing shingles. Very rarely, a second case of chickenpox does happen.

Detailed explanation-3: -Can you catch chickenpox again once you have had it? In most cases, getting chickenpox once means you will not get it again. This is called lifelong immunity.

Detailed explanation-4: -If you’ve had chickenpox, you’re at risk of a complication called shingles. The varicella-zoster virus remains in your nerve cells after the skin infection has healed. Many years later, the virus can reactivate and resurface as shingles-a painful cluster of short-lived blisters.
