Which of the following is a common disease caused by viruses?

Chicken pox is a disease that is specifically caused by the varicella-zoster virus, which is a type of virus. It is characterized by an itchy rash, fever, and the appearance of fluid-filled blisters. The virus is highly contagious and typically spreads through direct contact with the rash or through respiratory droplets when an infected person coughs or sneezes. Vaccination has made chicken pox less common, but it remains a significant example of a viral infection.

In contrast, Staphylococcus refers to a genus of bacteria, not a virus, and it is known to cause various infections, including skin infections and food poisoning. Athlete's foot is a fungal infection, caused primarily by dermatophytes, which are not viruses. Lice are parasites that infest hair and skin but are also not caused by viruses. Thus, chicken pox stands out as a common disease that originates from a viral source, highlighting the nature of viral infections.
