Which statement about varicella zoster is true?

Varicella zoster is correctly identified as a viral infection, which is responsible for causing chickenpox and shingles. This virus belongs to the herpesvirus family and is highly contagious. Individuals infected with the varicella zoster virus typically present with a characteristic itchy rash and flu-like symptoms.

The importance of recognizing this as a viral infection lies in its implications for transmission and treatment. While antiviral medications are available and can be effective in managing symptoms or complications, they are not the sole means of treatment. Additionally, varicella zoster is indeed contagious, primarily spread through respiratory droplets or direct contact with the rash of an infected person. Furthermore, there are effective vaccines available, such as the varicella vaccine, which help protect against chickenpox. Understanding these aspects underlines why identifying it as a viral infection is the crucial and accurate characterization.
