Whether tuberculosis can be completely cured varies from person to person. Most cases of tuberculosis, especially initial occurrences of pulmonary tuberculosis, can be cured in more than 80 to 90 percent of patients if they undergo standardized anti-tuberculosis treatment. However, it is essential that the treatment is standardized; it is not appropriate to simply take medication for one or two months and then stop when symptoms seem to disappear. The treatment duration for pulmonary tuberculosis is considered to be at least six months, and for some patients, it may even extend to a year. However, not all cases of pulmonary tuberculosis can be completely cured. A small percentage of patients may not achieve complete eradication due to resistance to tuberculosis bacteria or intolerance to the side effects of tuberculosis medications. In such cases, the prognosis might be poor, and some individuals may succumb to tuberculosis due to these factors.
