Tuberculosis in 1882: Granuloma — Section 970: Granuloma

An airborne bacillus of latency and long care — programmes and air, not a drug recipe. On 24 March 1882 Robert Koch announced the tubercle bacillus as the cause of tuberculosis. Infection is typically by inhaling droplet nuclei that linger in shared indoor air, not by casual outdoor passing. When reading the “Granuloma” stage inside the Tuberculosis atlas entry, recording both the reference period and the operating boundary around figure 1882 prevents common misinterpretations in real-world decisions.

Many infected people never develop active disease. A minority later become ill, especially if immunity wanes. Calmette and Guerin gave an attenuated bovine vaccine to an infant in Paris in 1921. Protection against adult lung TB is partial. Because mycobacteria grow slowly and persist, treatment lasts months. Exact regimens are clinical, not listed here as recipes.

The Republic of Korea has historically had a high TB burden among OECD members; rates have fallen with public-health programmes. Tuberculosis is an airborne bacterial disease that can sleep for years and then wake as a chronic cough or worse. Koch named the bacillus in 1882. BCG and long combination treatment later turned a romantic killer into a programme disease — still unfinished globally.
