• feeling tired or exhausted.
• a high temperature or night sweats.
• loss of appetite.
• weight loss.

What is silent tuberculosis?

People with latent TB infection are infected with TB bacteria, but they do not have TB disease. However, if these bacteria become active and multiply, latent TB infection can develop into TB disease.

What infection mimics tuberculosis?

There are more than 25 different species of mycobacteria that cause nontuberculous mycobacterial infections. One of the most common is Mycobacterium avium, which can cause symptoms similar to tuberculosis, such as cough, fever, fatigue, and weight loss.

Can one have TB and not know it?

This is called inactive TB or latent TB infection. People with inactive TB do not feel sick, do not have symptoms, and cannot spread TB germs to others. Without treatment, inactive TB can develop into active TB disease at any time and make you sick.

Can I kiss my partner if I have TB?

People who have TB disease in their throat or lungs spread the germs in the air when they cough, sneeze, talk, or sing. If you breathe in the air that has the germs, you can get TB. TB is not spread by touching, kissing, or sharing food or dishes.

Is TB 100% contagious?

Active TB disease in the lungs or throat can be infectious. This means the germs can spread to other people. TB disease in other parts of the body, such as the kidney or spine, is usually not infectious. People with active TB disease are most likely to spread it to people they spend time with every day.

Can I have a positive TB test without TB?

False-positive diagnoses for TB are usually considered to have minimal long-term health implications for patients. However, they can lead to substantial negative consequences—consequences that generally will not be later corrected.

Which organ is mostly affected by TB?

TB most commonly affects the lungs – what's known as the body's pulmonary system. But it affects other organs too, what's known as extrapulmonary TB.

What kills TB bacteria?

TB disease is curable. It is treated by standard 6 month course of 4 antibiotics. Common drugs include rifampicin and isoniazid. In some cases the TB bacteria does not respond to the standard drugs.

What can cause a false-positive TB blood test?

False-positive TB results usually happen because of prior BCG vaccination or exposure to non-tuberculosis mycobacteria in the environment. Your immune system reacts to these similar bacteria, which can trigger a positive test even when you do not have tuberculosis.

Can a normal blood test detect TB?

Blood is the “sentinel” for many diseases, because it can indicate both hematologic malignancies and tuberculosis infections. Routine blood tests can be widely used for the detection of active tuberculosis (ATB) infection.

Who is most at risk for TB?

People at high risk for progression to TB disease once infected include: Persons with human immunodeficiency virus HIV infection. Persons who were infected with M. tuberculosis within the past 2 years, particularly infants and very young children.

What does the beginning of TB feel like?

Common symptoms of active TB disease include cough, pain in the chest, and coughing up blood or sputum (phlegm). People with inactive TB, also called latent TB infection, do not have symptoms of TB disease and cannot spread TB to others.

Can TB go away on its own?

Tuberculosis symptoms can seem to go away, but the illness often reactivates. Without treatment, tuberculosis can return. Tuberculosis treatment regimens last for months. Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis bacteria that usually affects the lungs.

What could be mistaken for TB?

Interstitial lung diseases are the disorders that are frequently unrecognized and misdiagnosed. More commonly the confusion is with tuberculosis.

Is tuberculosis considered an STD?

Genital tuberculosis is a sexually transmitted infection that can affect both men and women. It is caused by the bacteria Mycobacterium tuberculosis. Genital TB can be passed from person to person through vaginal, anal, or oral sex with an infected partner.

Is TB a death-causing disease?

Globally, TB is the world's leading cause of death from a single infectious agent and among the top 10 causes of death. TB was also both the leading killer of people with HIV in 2024 and a major cause of deaths related to antimicrobial resistance.

What is a non-TB infection?

Non-tuberculous mycobacteria (NTM) are ubiquitously present in the environment, but NTM diseases occur infrequently. NTM are generally considered to be less virulent than Mycobacterium tuberculosis, however, these organisms can cause diseases in both immunocompromised and immunocompetent hosts.

Can you have mild tuberculosis?

Tuberculosis (TB) is an illness caused by a bacterial infection. It commonly affects your lungs, but it can also affect other areas of your body like your spine, brain or kidneys. Not everyone who's infected with TB gets sick. If you're infected but have no symptoms, it's called inactive tuberculosis, or latent TB.

Does a chest xray show latent TB?

A person has latent TB infection if they have a positive TB skin test and a normal (negative) chest x-ray. This means the person has breathed in the TB germs, but his or her body has been able to fight the germs. People with latent TB infection do not feel sick and do not have signs of TB disease.
