The correct answer is: Contagious.
Tuberculosis is a contagious disease caused by bacteria called Mycobacterium tuberculosis. It is spread through the air when an infected person coughs, sneezes, or talks. The bacteria can be inhaled by people who are nearby.
Tuberculosis can affect any part of the body, but it most commonly affects the lungs. Symptoms of tuberculosis can include a cough that lasts for more than two weeks, chest pain, fatigue, weight loss, and night sweats.
If left untreated, tuberculosis can be fatal. However, it is a treatable disease. Treatment usually involves a combination of antibiotics that are taken for several months.
The other options are incorrect because:
- Infectious: A disease that can be spread from one person to another is called an infectious disease. Tuberculosis is an infectious disease.
- Contiguous: A disease that can be spread through direct contact with an infected person or animal is called a contiguous disease. Tuberculosis is not a contiguous disease.
- Fatal: A disease that can cause death is called a fatal disease. Tuberculosis can be fatal, but it is not always fatal.
