Tuberculosis
Tuberculosis (TB) is an infectious disease caused by the bacterium Mycobacterium tuberculosis. Here are the correct statements about tuberculosis:
- Treatment for active TB can last up to 12 months. Active TB requires a combination of antibiotics taken for an extended period to ensure complete eradication of the bacteria.
- Someone who is coughing up blood may have TB. Hemoptysis, which is coughing up blood, is a symptom commonly associated with active TB.
- If not treated promptly, TB can be fatal. TB can be a deadly disease if left untreated, which is why it is important to seek medical attention as soon as symptoms appear.
It is not true that even a person with latent TB can easily spread the disease. Latent TB infection means the bacteria are present in the body but are inactive; they do not cause symptoms or spread to others unless the infection becomes active. Additionally, the statement that all people in the U.S. should get vaccinated against TB is incorrect. There is a vaccine available for TB, called the Bacille Calmette-Guérin (BCG) vaccine, but it is not routinely recommended for all people in the U.S. because the risk of infection is low.
