contagious person for a long time. For that reason, you're more likely to catch TB from a relative than a stranger." If a person had latent tuberculosis, they do not have active/contagious tuberculosis. Once exposed, people very often have latent tuberculosis. To convert to active tuberculosis, the bacteria must become active. In some Countries like Canada people have medical privacy or "confidentiality" and do not have to reveal their active tuberculosis case to family, friends, or co-workers; therefore, the person who gets latent tuberculosis may never know who had the active case of tuberculosis that caused the latent tuberculosis diagnosis for them. Only by required testing (required in some jobs) or developing symptoms of active tuberculosis and visiting a medical doctor who does testing will a person know they have been exposed. Because tuberculosis is not common in the United States, doctors may not suspect tuberculosis; therefore, they may not test. If a person has symptoms of tuberculosis, it is wise to be tested. Persons with diabetes may have an 18% chance of converting to active tuberculosis. In fact, death from tuberculosis was greater in diabetic patients. Persons with HIV and latent tuberculosis have a 10% chance of developing active tuberculosis every year. "HIV infection is the greatest known risk factor for the progression of latent M. tuberculosis infection to active TB. In many African countries, 30–60% of all new TB cases occur in people with HIV, and TB is the leading cause of death globally for HIV-infected people." Reactivation Once a person has been diagnosed with Latent Tuberculosis (LTBI) and a medical doctor confirms no active tuberculosis, the person should remain alert to symptoms of active tuberculosis for the remainder of their life. Even after completing the full course of medication, there is no guarantee that the tuberculosis bacteria have all been killed."When a person develops active TB (disease), the symptoms (cough, fever, night sweats, weight loss etc.) may be mild for many months. This can lead to delays in seeking care, and results in transmission of the bacteria to others." Tuberculosis does not always settle in the lungs. If the outbreak of tuberculosis is in the brain, organs, kidneys, joints, or others areas, the patient may have active tuberculosis for an extended period of time before discovering that they are active. "A person with TB disease may feel perfectly healthy or may only have a cough from time
