Which condition is caused by a virus?

Chicken pox is the condition caused by a virus, specifically the varicella-zoster virus. It is a highly contagious disease characterized by an itchy skin rash filled with fluid-filled blisters, fever, and fatigue. Chicken pox primarily affects children, although it can occur in individuals of any age.

Strep throat is caused by bacteria, specifically Streptococcus pyogenes, leading to a sore throat, fever, and swollen lymph nodes. Impetigo is also bacterial, typically resulting from infections with Staphylococcus aureus or Streptococcus pyogenes, and presents with red sores or blisters. Hepatitis B is a viral infection affecting the liver, caused by the hepatitis B virus, but is less associated with the characteristic rash and symptoms typically described alongside chicken pox.

Understanding that chicken pox is the viral condition in this list highlights the importance of identifying the underlying causes of various illnesses, whether viral or bacterial, in the context of health and safety practices.
