VZV (Varicella-Zoster Virus)

Varicella-Zoster Virus (VZV) is a member of the herpesvirus family that causes two main conditions: chickenpox and shingles. When a person first encounters the virus, it often results in chickenpox, marked by an itchy rash and flu-like symptoms. After recovery, the virus remains dormant in nerve tissues. Later in life, it can reactivate as shingles, causing a painful, localized skin rash. VZV spreads through respiratory droplets or direct contact with the rash. Vaccination exists to prevent these illnesses, reducing their severity and complications.
