Tuberculosis is spread from one person to the next through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. [1] [9] People with latent TB do not spread the disease. [1] Active infection occurs more often in people with HIV/AIDS and in those who smoke. [1]
Management of tuberculosis refers to techniques and procedures utilized for treating tuberculosis (TB), or simply a treatment plan for TB.. 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.
So, if a person with TB of the lungs sneezes, coughs, talks, sings, or does anything that forces the bacteria into the air, other people nearby may breathe in TB bacteria. Statistics show that approximately one-third of people exposed to pulmonary TB become infected with the bacteria, but only one in ten of these infected people develops active ...
Resistant strains of M. tuberculosis have developed resistance to more than one TB drug, due to mutations in their genes. In addition, pre-existing first-line TB drugs such as rifampicin and streptomycin have decreased efficiency in clearing intracellular M. tuberculosis due to their inability to effectively penetrate the macrophage niche.

In addition, between 1851 and 1910, around four million died from TB in England and Wales – more than one third of those aged 15 to 34 and half of those aged 20 to 24 died from TB. [62] By the late 19th century, 70–90% of the urban populations of Europe and North America were infected with the Mycobacterium tuberculosis , and about 80% of ...

People who are poor are disproportionately affected by tuberculosis because the disease is made worse by inadequate housing and malnutrition, and poverty can make it difficult to get treatment. The WHO has estimated that eliminating poverty would reduce tuberculosis incidence by 84 percent.
Almost one in four people in the world are infected with TB bacteria. [1] Only when the bacteria become active do people become ill with TB. Bacteria become active as a result of anything that can reduce the person's immunity, such as HIV, advancing age, diabetes or other immunocompromising illnesses.
