How TB Works

TB is a bacterial infection caused by Mycobacterium tuberculosis. The bacteria primarily affect the lungs, but can also spread to other parts of the body. Typically, individuals become infected with TB when they inhale bacterial particles that are released into the air when an infected person coughs, sneezes, or talks. TB symptoms can be slow to develop and may include coughing, chest pain, fever, and unexplained weight loss.

Common Misconceptions

Lately, Tuberculosis (TB) has been making headlines globally, and the United States is no exception. With the increasing global health concerns, it's essential to separate fact from fiction and myth from reality regarding this disease. As the number of TB cases in the US continues to rise, it's crucial to understand the facts behind this ancient disease to make informed decisions about our health and the health of those around us.

    Q: Is TB contagious if it's in the latent stage?

    Efficient treatment can cure TB, and when caught early, cure rates are around 95%. However, delays in diagnosis can lead to more severe disease, complications, and increased risks of being contagious. Taking the appropriate precautions and keeping health services informed can help prevent further spread and prevent the disease.

    TB can be transmitted from animals to humans, although it's relatively rare. Cattle, deer, and cats are among the animals that can carry TB. However, human-to-human transmission remains the primary mode of spread.

      An individual with latent TB is not contagious, as the bacteria are dormant and inactive. However, untreated latent TB can develop into active TB, making it essential to complete treatment to prevent progression to the active stage.
