- Tuberculosis (TB) killed hundreds in the late 1800s and early 1900s. In the 1950s drugs were developed that effectively fought TB. This significantly reduced the number of deaths in developed countries but poor and developing countries continued unabated. By the mid-1980s new drug-resistant strains emerged and TB moved back into developed countries.
