What is the common term for the illness characterized by fever, chills, and body aches caused by a specific virus?

The illness characterized by fever, chills, and body aches caused by a specific virus is commonly known as the flu, or influenza. This viral infection primarily affects the respiratory system and is notorious for causing outbreaks during certain seasons. The symptoms of fever, chills, and body aches are hallmark signs of the flu, which set it apart from other conditions.

While pneumonia can present with fever and chills, it is typically a complication of other respiratory infections and more commonly associated with bacterial infections, rather than being primarily identified with a singular viral cause. Bronchitis also involves respiratory symptoms but usually presents with a cough and is often not associated with systemic symptoms like fever and body aches. Coronary artery disease, on the other hand, is a heart condition related to blood vessels and does not exhibit these flu-like symptoms. Hence, the flu is the most accurate answer given the described symptoms.
