TB spreads when infectious bacteria enter the air and the immune system responds. With LTBI, people typically have no symptoms, feel well, and cannot transmit TB bacteria. Active TB occurs when the bacteria overcome immunity, causing serious illness.

When someone with the bacteria in their lungs coughs or sneezes, they can send the bacteria into the air. If you breathe in the bacteria into your body, your body immune system will try to fight the bacteria.  \nIf your body immune system is well, it will win over the bacteria...  \nBut...in my country, I have never heard of LTBI or its treatment...  \nCountries have different policies for dealing with LTBI, depending on priorities- if your country has lots of active TB, then priority may be given to finding and treating persons with active TB to prevent further transmission to others.  \nThat may be a reason why you have never heard of LTBI or LTBI treatment in your country. In Japan, because we have less and  \n... it will suppress the bacteria and keep it \"sleeping\" in your body-this is called latent TB infection( LTBI).  \nIf you have LTBI, you do not have symptoms. You feel well, and you cannot pass the TB bacteria to others.  \nBut If the bacteria wins over your body immune system...  \n... it can make you very sick-this is called \"active TB\".  \nIf you have active TB, it can threaten your life and also pass the disease to your family and friends.  \nless persons with active TB, we also try to find and treat persons with LTBI.  \nAbout Us  \nWe are the only Non-Governmental Organization that is dedicated solely to fighting TB in Japan.  \nThe Research Institute of Tuberculosis, Japan Anti-Tuberculosis Association.

Do I have to stop working?  \n  Do I have to stop my school?  \nIf your doctor thinks you may be at a higher risk of developing active TB, the doctor will suggest you to take medications to get rid of the bacteria in your body.  \nThere are several types of treatment courses. The most common treatment in Japan is a combination of two drugs (isoniazid and r ifampic in) for 3-4 months. You can consult your doctor to decide what is the best treatment for you. Treatment for LTBI is shorter, requires less medications and less costly than treatment for active TB.  \nAbsolutely not. LTBI does NOT mean you have a disease. You do not need to stop working, or stop studying. You can continue to live your everyday life, like a healthy person.  \nYou will be asked to visit your doctor once in a while to make sure you do not have any side effects from the medicines.  \nBut what if I am told that I can no longer work or study?    \nLTBI can be treated quickly. Treatment may be just 3-4 months. It is shorter, needs less medicines, and less costly than treatment for active TB.  \nIf you think you are being treated unfairly because you have LTBI, you can ask for advice, in your language, from  \nJapan Anti-Tuberculosis Association telephone consultation:  \n03-3292-1218 Every Tuesday  \n10:00-12:0","cbCaiekbg5qLnwIh","https://ap.wps.com/l/cbCaiekbg5qLnwIh","pdf",769414,"English","# What is the difference between tuberculosis (TB) and latent tuberculosis infection (LTBI)?\n## TB vs LTBI: symptoms and transmission\n## Country policies and risk factors\n## Treatment and everyday life guidance","[{\"question\":\"How are tuberculosis (TB) and latent TB infection (LTBI) different?\",\"answer\":\"TB is an active disease that can spread when infected people cough or sneeze and bacteria enter the air.
