What are the three types of tuberculosis?

What are the three types of tuberculosis?

Tuberculosis: Types

• Active TB Disease. Active TB is an illness in which the TB bacteria are rapidly multiplying and invading different organs of the body.
• Miliary TB. Miliary TB is a rare form of active disease that occurs when TB bacteria find their way into the bloodstream.
• Latent TB Infection.

What does Mycobacterium tuberculosis do to the body?

Tuberculosis (TB) is caused by a bacterium called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain. Not everyone infected with TB bacteria becomes sick.

What is meant by miliary TB?

Miliary TB is a potentially fatal form of TB that results from massive lymphohematogenous dissemination of Mycobacterium tuberculosis bacilli. The epidemiology of miliary TB has been altered by the emergence of the human immunodeficiency virus (HIV) infection and widespread use of immunosuppressive drugs.

Is latent TB common?

In the United States, up to 13 million people may have latent TB infection. Without treatment, on average 1 in 10 people with latent TB infection will get sick with TB disease in the future. The risk is higher for people with HIV, diabetes, or other conditions that affect the immune system.

Does latent TB go away after treatment?

A course of antibiotic medicine will treat latent TB. You may be given Rifampicin and Isoniazid for three months (which may be together in a tablet called Rifinah) or Isoniazid by itself for six months.

What are the two stages of TB?

There are 3 stages of TB: exposure, latent, and active disease. A TB skin test or a TB blood test can often diagnose the infection. But other testing is also often needed. Treatment exactly as recommended is needed to cure the disease and prevent its spread to other people.

How long can you live with untreated tuberculosis?

Left untreated,TB can kill approximately one half of patients within five years and produce significant morbidity (illness) in others. Inadequate therapy for TB can lead to drug-resistant strains of M. tuberculosis that are even more difficult to treat. Not everyone who inhales the germ develops active TB disease.

What is the difference between pulmonary TB and miliary TB?

Tuberculosis (TB) is a serious infection that usually affects only your lungs, which is why it’s often called pulmonary tuberculosis. However, sometimes the bacteria get into your blood, spread throughout your body, and grow in one or several organs. This is called miliary TB, a disseminated form of tuberculosis.

Is miliary TB extrapulmonary and pulmonary?

Tuberculosis may be classified according to site of disease as pulmonary or extrapulmonary; miliary disease has been classified as both an extrapulmonary and a pulmonary form of TB.

What do you need to know about tuberculosis?

Tuberculosis: General Information. What is TB? Tuberculosis (TB) is a disease caused by germs that are spread from person to person through the air. TB usually affects the lungs, but it can also affect other parts of the body, such as the brain, the kidneys, or the spine. A person with TB can die if they do not get treatment.

What is the protean presentation of tuberculosis?

Tuberculosis (TB) is an ancient human disease caused by Mycobacterium tuberculosiswhich mainly affects the lungs, making pulmonary disease the most common presentation (K Zaman, 2010). However, TB is a multi-systemic disease with a protean presentation.

What are the chances of falling ill with tuberculosis (TB)?

People infected with TB bacteria have a 5–10% lifetime risk of falling ill with TB. Those with compromised immune systems, such as people living with HIV, malnutrition or diabetes, or people who use tobacco, have a higher risk of falling ill.

Can tuberculosis be treated without treatment?

Both latent TB infection and active TB disease can be treated. Without treatment, latent TB infection can progress to TB disease, and without proper treatment, TB disease can kill. Why Is the Study of Tuberculosis a Priority for NIAID?
