Varicel

Varicel is a term that appears to be a misspelling or a less common variant of the word varicella. Varicella is the medical term for chickenpox, a highly contagious infectious disease caused by the primary infection with the varicella-zoster virus (VZV). It is characterized by an itchy rash that forms blisters, which then scab over. The rash typically appears first on the trunk and face, and then spreads throughout the body. Other symptoms can include fever, fatigue, and headache, usually appearing one to two days before the rash.

Chickenpox is most common in children but can occur at any age. Once a person has had chickenpox, they are generally immune to reinfection, although the virus can reactivate later in life to cause shingles (herpes zoster). Transmission of VZV occurs through direct contact with the rash or through airborne droplets from an infected person's coughs or sneezes. The incubation period is typically between 10 to 21 days after exposure.

Diagnosis is usually made based on the characteristic rash and symptoms. There is no specific cure for chickenpox, and treatment focuses on relieving symptoms, such as itching. Antiviral medications may be prescribed for individuals at higher risk of complications. A highly effective vaccine for chickenpox is available and recommended for routine childhood immunization, significantly reducing the incidence of the disease and its complications.
