per cent (in patients with positive LTBI test results and fibrotic pulmonary lesions compatible with tuberculosis) if taken daily for 9 months." However, if a person has not completed the medication exactly as prescribed, the "cure" is less likely, and the "cure" rate is directly proportional to following the prescribed treatment specifically as recommended. Furthermore, "[I]f you don't take the medicine correctly and you become sick with TB a second time, the TB may be harder to treat if it has become drug resistant." If a patient were to be cured in the strictest definition of the word, it would mean that every single bacterium in the system is removed or dead, and that person cannot get tuberculosis (unless re-infected). However, there is no test to assure that every single bacterium has been killed in a patient's system. As such, a person diagnosed with latent TB can safely assume that, even after treatment, they will carry the bacteria – likely for the rest of their lives. Furthermore, "It has been estimated that up to one-third of the world's population is infected with M. tuberculosis, and this population is an important reservoir for disease reactivation." This means that in areas where TB is endemic treatment may be even less certain to "cure" TB, as reinfection could trigger activation of latent TB already present even in cases where treatment was followed completely. Epidemiology Tuberculosis exists in all countries in the world, though some countries have a larger number of people infected than others. Per 100,000 people, Eswatini has the greatest number of tuberculosis cases in the world (627). Second is Cambodia (560), followed by Zambia (445), fourth is Djibouti (382), fifth is Indonesia (321), Mali (295), Zimbabwe (291), Kenya (291), Papua New Guinea (283) and Gambia (283). The United States, Sweden and Iceland have some of the lowest rates of tuberculosis at 2 per 100,000. Canada, Netherlands, Jamaica, Norway, Malta, Grenada and Antigua and Barbuda also have low infection rates, at 3 per 100,000. In North America, countries over 10:100,000 include Mexico (14), Belize (18), Bahamas (19), Panama (28), El Salvador (36), Nicaragua (35), Honduras (46), Guatemala (48), and the Dominican Republic (88). Most Western European countries have less than 10 per 100,000 except Spain (14), Portugal (16), Estonia (27), Latvia (43) and Lithuania (48), while Eastern and Southern European countries tend to have a greater number, with Romania (94) being the
