What is a member of the herpes virus family that causes variety diseases?

The correct answer is Varicella-zoster virus.

Varicella-zoster virus (VZV) is a member of the herpes virus family that causes two common diseases: chickenpox (varicella) and shingles (herpes zoster).

Chickenpox is a highly contagious disease that is characterized by an itchy rash of small, fluid-filled blisters. Chickenpox is usually a mild disease in children, but it can be more severe in adults and people with weakened immune systems.

Shingles is a painful skin rash that is caused by the reactivation of the varicella-zoster virus. Shingles can occur in anyone who has had chickenpox, but it is most common in adults over the age of 50.

VZV is a highly contagious virus that is spread through contact with the blisters of someone who has chickenpox or shingles. The virus can also be spread through the air by coughing or sneezing.
