Verified step by step guidance

Understand the nature of varicella zoster virus (VZV): It is a virus, not a bacterium, so antibiotics are ineffective against it.

Recognize the transmission method: VZV is primarily transmitted through respiratory droplets, not through contaminated food and water.

Identify the initial infection: VZV causes chickenpox, a common childhood illness characterized by an itchy rash and flu-like symptoms.

Learn about reactivation: After the initial infection, VZV can remain dormant in the body and reactivate later in life as shingles, which is characterized by a painful rash.

Consider vaccination: While vaccination can prevent chickenpox, VZV can affect individuals regardless of their vaccination status, especially in the form of shingles.
