In people with smear-positive pulmonary TB (without HIV co-infection), after 5 years without treatment, 50–60% die while 20–25% achieve spontaneous resolution (cure). TB is almost always fatal in those with untreated HIV co-infection and death rates are increased even with antiretroviral treatment of HIV. [168]

The medical standard for active TB is a short course treatment involving a combination of isoniazid, rifampicin (also known as Rifampin), pyrazinamide, and ethambutol for the first two months.

Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.

[2] In August 2019, the Food and Drug Administration (FDA) approved the use of pretomanid in combination with bedaquiline and linezolid for treating a limited and specific population of ...
When he reached the 100-patient limit this past March, he convinced his nephew, a certified doctor practicing in North Dakota (he was not prescribing buprenorphine at the time), to help. Now, once a month for a week, his nephew travels from North Dakota to work at the clinic. “This is not really sustainable,” McCoy said several months ago.
