Varicella zoster
Varicella zoster (pronounced: vuh-RIK-uh-luh ZOS-ter), also known as Chickenpox or Shingles, is a highly contagious virus that causes an infectious disease.
Etymology
The term "Varicella" is derived from the Latin word varicellus, which means "smallpox". The term "Zoster" is derived from the Greek word zōstēr, which means "girdle" or "belt". This refers to the characteristic rash that often wraps around one side of the body.
Symptoms
The primary symptom of Varicella zoster is a rash that develops into itchy, fluid-filled blisters that eventually turn into scabs. Other symptoms may include fever, fatigue, headache, and loss of appetite.
Transmission
Varicella zoster is transmitted through direct contact with the rash, or through the air when an infected person coughs or sneezes.
Treatment
Treatment for Varicella zoster includes antiviral medications, such as Acyclovir, to reduce the severity and duration of the disease. Pain medications may also be used to relieve the discomfort caused by the rash.
Prevention
Prevention of Varicella zoster is possible through the Varicella vaccine, which is recommended for all children and adults who have not previously had chickenpox.
