Chickenpox, medically known as varicella, is a highly contagious viral infection caused by the varicella-zoster virus. It primarily affects children but can also occur in adults who have not previously contracted the disease or been vaccinated. Characterized by an itchy rash that develops into fluid-filled blisters, chickenpox is often accompanied by fever, fatigue, and loss of appetite. The rash typically appears in waves, beginning on the face, chest, and back before spreading to the rest of the body. Understanding the signs and symptoms of chickenpox is essential for parents to recognize the condition early and manage their child's health effectively.
