Varicella-zoster is the virus that causes chickenpox. The average incubation period is 14 to 16 days after exposure. A person usually experiences a mild fever and fatigue for 1 to 2 days before rashes appear all over the body. A person having had chickenpox as a child may have the virus lay inactive in the nerve cells for many years only to reactivate much later as an adult in the form of shingles, which results in a very painful rash. This information suggests that the reproductive cycle of the varicella virus is - a)lytic for shingles because the virus causes rashes to appear on the skin.

b) lysogenic for chickenpox because the virus attacks the mucous membranes.

c) lysogenic because the virus is a varicella-zoster virus.

d) lytic for chickenpox because the symptoms appear soon after infection.
