Chickenpox

Chickenpox is a highly contagious viral disease caused by the varicella-zoster virus. It is transmitted through the air or by direct contact with the blisters of an infected person. The disease occurs worldwide and most commonly affects children.

Typical symptoms include fever, fatigue, and an itchy, blistering rash that gradually spreads throughout the body. In most children, the disease progresses without complications; however, it can take a more severe course in adults, pregnant women, and people with weakened immune systems.

After an infection, the virus remains in the body for life and may later become active as shingles. The most effective prevention is vaccination, which significantly reduces the risk of the disease and its complications.
