Varicella-zoster virus (VZV) is a common virus that causes two distinct illnesses: chickenpox (varicella) and shingles (herpes zoster). Chickenpox is a highly contagious childhood disease that causes an itchy rash and fever. Shingles is a painful rash that typically occurs on one side of the face or body.

A VZV positive test result means that you have been exposed to the varicella-zoster virus and have developed antibodies to it. This means that you are immune to chickenpox, but you may still develop shingles later in life.

What are the Symptoms of Chickenpox?

Symptoms of chickenpox usually appear 10 to 21 days after exposure to the virus. The most common symptoms of chickenpox include:

  • Fever
  • Itchy rash that starts on the face and spreads to the rest of the body
  • Small, fluid-filled blisters that break open and crust over
  • Fatigue
  • Loss of appetite

What are the Symptoms of Shingles?

Symptoms of shingles usually appear on one side of the face or body. The most common symptoms of shingles include:

  • Painful rash that starts as small, red blisters that break open and crust over
  • Tingling or burning sensation in the area of the rash
  • Fever
  • Fatigue
  • Headache

How is VZV Diagnosed?

VZV is typically diagnosed based on your symptoms and a physical exam. However, a blood test can also be used to confirm the diagnosis.

What is the Treatment for VZV?

There is no cure for VZV, but there are treatments that can help relieve the symptoms. Chickenpox is usually treated with over-the-counter medications to relieve fever and itching. Shingles can be treated with antiviral medications and pain relievers.

How can I Prevent VZV?

The best way to prevent VZV is to get vaccinated. The varicella vaccine is a safe and effective vaccine that can protect you from chickenpox and shingles.

What should I do if I test positive for VZV?

If you test positive for VZV, you should talk to your doctor about your risk of developing chickenpox or shingles. Your doctor may recommend that you get vaccinated if you have not already done so.
