What happens if you have latent TB?
People with latent TB infection do not have symptoms, and they cannot spread TB bacteria to others.
However, if latent TB bacteria become active in the body and multiply, the person will go from having latent TB infection to being sick with TB disease..
How did I get latent tuberculosis?
Latent TB occurs when a person has the TB bacteria within their body, but the bacteria are present in very small numbers. They are kept under control by the body’s immune system and do not cause any symptoms.
Is it safe to be around someone with TB?
No. It is very important to remember that only someone with active TB disease in the lungs can spread the germ. People with TB infection are not contagious, do not have any symptoms, and do not put their family, friends and co-workers at risk.
Will latent TB show up on xray?
Individuals with latent TB infection are not infectious. They are negative to most TB tests including culture, Nucleic Acid Amplification Tests (NAAT), and smear microscopy. Small nodules are occasionally seen on chest x-ray or CT scan.
Does latent TB show up in a blood test?
A “positive” TB blood test result means you probably have TB germs in your body. Most people with a positive TB blood test have latent TB infection. To be sure, your doctor will examine you and do a chest x-ray. You may need other tests to see if you have latent TB infection or active TB disease.
Can latent TB be cured completely?
When people talk about TB, they tend to mean ‘active TB’. If you have active TB, the bacteria are making you ill and you might be passing TB on to other people. Active TB can be very harmful to your health, but it can be cured with a course of medicine. If you have latent TB, the TB bacteria in your body are ‘asleep’.
Can I work with latent TB?
A person with Latent TB infection does not feel sick and cannot spread TB to others. These people do not have to take any precautions to stop the spread of TB. They should continue to go to work/school and do their normal activities.
Should I be worried if I have latent TB?
You have been invited for a latent TB test because you are at increased risk of becoming ill with TB. There is no need to be worried. Latent TB can be treated before it can cause active TB, and all testing and treatment for TB is free and confidential for everyone.
What are the signs and symptoms of latent TB?

Can latent TB come back after treatment?
Even with treatment, however, tuberculosis reinfection is becoming a problem. It’s very common for people with tuberculosis to relapse during treatment. Treatment for tuberculosis symptoms can last anywhere from six months to a year, and sometimes more for drug-resistant tuberculosis.
Are you contagious with latent TB?
Persons with latent TB infection are not infectious and cannot spread TB infection to others. Overall, without treatment, about 5 to 10% of infected persons will develop TB disease at some time in their lives. About half of those people who develop TB will do so within the first two years of infection.
How long does latent TB last?
There is no evidence about repeated courses of preventive treatment, and hence no recommendation is made in the present guidelines. However, in settings with high TB transmission (as defined by local authorities), isoniazid for 36 months (as a proxy for life long therapy) is recommended for PLHIV.
Does Tuberculosis stay in your system forever?
What is latent TB infection? Many people who have latent TB infection never develop TB disease . In these people, the TB bacteria remain inactive for a lifetime without causing disease . But in other people, especially people who have weak immune systems, the bacteria become active, multiply, and cause TB disease .
What percentage of latent TB becomes active?
Treatment. The treatment of latent tuberculosis infection (LTBI) is essential to controlling and eliminating TB by reducing the risk that TB infection will progress to disease. Latent tuberculosis will convert to active tuberculosis in 10% of cases (or more in cases of immune compromised patients).
