Which infectious disease may affect nearly all tissues, especially the lungs?

• A. Urinary Tract Infection
• B. Aphasia Communication
• C. Tuberculosis
• D. Gene Testing

Answer: (C)

Diseases that start in the lungs but can spread to many tissues are best illustrated by tuberculosis. Tuberculosis is caused by Mycobacterium tuberculosis and is primarily a pulmonary infection, meaning the lungs are the main site. But the bacteria can escape the lungs via the bloodstream and lymphatic system, leading to involvement of other tissues and organs such as lymph nodes, bones, joints, the lining of the brain (meninges), kidneys, and the abdomen. This ability to affect multiple tissues, with the lungs as the central starting point, is what makes it the most fitting choice for a disease that may involve nearly all tissues. Other options don’t fit because they don’t describe an infectious disease that commonly affects a wide range of tissues, especially the lungs. A urinary tract infection is usually limited to the urinary system; aphasia is a language impairment, not an infectious disease; gene testing is a diagnostic process, not an infectious disease.
