Overview

Mycobacteria tuberculosis was first described by Robert Koch in 1882 and in 1970 drug-resistant tuberculosis was first reported. Since then, several drugs and strategies have been implemented to control the disease. Cases in US have decreased, however worldwide MDR-TB is increasing in developing countries.

Historical Perspective

  • Tuberculosis has been present in humans since antiquity. The earliest unambiguous detection of Mycobacterium tuberculosis was in the remains of bison, dated 18,000 BC.[1]
  • However, whether tuberculosis originated in cattle and then transferred to humans, or diverged from a common ancestor, is currently unclear.[2]
  • Through history tuberculosis had many names, such as phthisis and Wasting disease, which were mostly derived from its symptoms.
  • The rod-shaped bacteria Mycobacterium tuberculosis was only identified in 1882 by Robert Koch.
  • In the 19th and early 20th centuries, tuberculosis caused the most widespread public concern, being considered an endemic disease of the urban poor. In 1946, the development of streptomycin made possible the treatment and cure for tuberculosis.
  • During the 1970s, a multi-drug resistant mycobacterium tuberculosis was first described. [3]
  • In 1990, the DOTS strategy was first introduced by WHO to prevent patient's drop-out from the medical regimen.[4]
  • Since 1993 the proportion of patients with primary multidrug-resistant (MDR) TB decreased from 3% to 1% by 1998. [4]
  • During 2009 through 2013, the percentage of primary MDR TB cases has remained stable at approximately 1%. [4]
  • Since 1997, the percentage of U.S.-born patients with primary MDR TB has remained below 1%. [4]
  • However, of the total number of reported primary MDR TB cases, the proportion occurring in foreign-born persons increased from 25% (103 of 407) in 1993 to 92% (75 of 82) in 2013.[4]
  • In 2012, an estimated of 450 000 cases of MDR-TB were reported and there were an estimated 170 000 deaths from MDR-TB.[5]
  • Also, the WHO reported that 3.6% of newly diagnosed TB cases were drug resistant and 20% of previously treated patients developed multi-drug resistant TB.
