Video - Varicella zoster virus

Varicella zoster virus (VZV) is a virus that causes two different diseases, chickenpox (varicella) and shingles (herpes zoster). Chickenpox is a highly contagious disease that primarily affects children, causing an itchy rash, fever, and other symptoms. The virus can be transmitted through direct contact with the rash, as well as through the air. Shingles is a painful condition that occurs when the virus reactivates later in life, usually in older adults or people with weakened immune systems. Shingles typically cause a painful rash, blisters, and other symptoms, and can sometimes lead to long-term nerve pain. The virus is spread through direct contact with the shingles rash. Vaccines are available to help prevent both chickenpox and shingles, and antiviral medications can be used to treat both conditions.
