Chicken pox
Chickenpox (pronunciation: /ˈtʃɪkənˌpɒks/) is a highly contagious disease caused by the initial infection with varicella zoster virus (VZV). The disease results in a characteristic skin rash that forms small, itchy blisters, which eventually scab over.
Etymology
The term "chickenpox" was first used in the 17th century. The name is believed to be derived from chickpeas, due to the resemblance of the vesicles to chickpeas, or from the rash resembling chicken pecks.
Symptoms
Chickenpox is characterized by a number of symptoms, including a high fever, fatigue, loss of appetite, and a headache. The most distinctive symptom, however, is the itchy rash that appears on the body. This rash develops into small, fluid-filled blisters that eventually crust over and form scabs.
Transmission
Chickenpox is highly contagious and is spread from person to person by direct contact, or through the air from an infected person's coughing or sneezing. A person with chickenpox is contagious from 1-2 days before the rash appears until all the blisters have formed scabs.
Treatment
There is no cure for chickenpox, but the disease usually resolves on its own within a week or two. Treatment typically involves relieving symptoms, such as using over-the-counter medications to reduce fever and itching. In severe cases, antiviral medications may be prescribed.
Prevention
The best way to prevent chickenpox is through vaccination. The chickenpox vaccine is safe and effective and is part of routine childhood immunization programs in many countries.
