Chickenpox is a common disease today. Chickenpox is considered a benign disease, however, the disease will cause some dangerous complications if not treated properly. To determine the presence of chickenpox virus in the body, the doctor will order a chickenpox test.

Chickenpox is a highly contagious disease caused by a virus (varicella zoster virus - abbreviated as VZV). This virus also causes shingles (also known as herpes zoster). Before the chickenpox vaccine, up to 90% of people would get the disease before the age of 15. Today, thanks to the vaccine, the disease is less common, but small outbreaks still occur in Vietnam in the spring.
