The term 'Viral Bug' can be summarized as a type of infectious disease caused by a virus. The most common example of this is the FLU, which is a three-letter word that can be used to describe a viral bug. Viral bugs are highly contagious and can spread quickly from person to person. They can cause symptoms such as fever, chills, body aches, and fatigue. Treatment for viral bugs typically involves rest, fluids, and over-the-counter medications. In some cases, antiviral medications may be prescribed to help reduce the severity of symptoms.
