Which condition is NOT caused by a virus?

• A. Mumps
• B. Tuberculosis
• C. Respiratory infections
• D. Common cold

Answer: (B)

Tuberculosis is a bacterial infection caused by Mycobacterium tuberculosis, rather than a viral condition. It primarily affects the lungs but can also impact other parts of the body. Unlike virus-induced diseases, which rely on hijacking host cell machinery to replicate, bacterial infections like tuberculosis reproduce independently, making them a distinct category of pathogens. In contrast, mumps, respiratory infections, and the common cold are all caused by viruses. Mumps is caused by the mumps virus, respiratory infections can be due to various viruses such as influenza or the common cold virus (rhinovirus), and the common cold itself is primarily caused by various viral pathogens. Understanding these distinctions is crucial for effective treatment and prevention strategies in both clinical and esthetic settings.
