TB-stamps in honour of Koch

\"\"By-Dr.Pradeep Jain

Tuberculosis or TB is a common and often deadly infectious disease caused by various strains of mycobacteria, usually Mycobacterium tuberculosis in humans.In 1882, the microbiologist Robert Koch discovered the tubercle bacillus, at a time when one of every seven deaths in Europe was caused by TB.On his name this disease is also called as Koch’s lesion. Because antibiotics were unknown, the only means of controlling the spread of infection was to isolate patients in private sanitoria or hospitals limited to patients with TB—a practice that continues to this day in many countries.In\"\"Europe this was the main cause of death.In 1938 there were about 700 TB sanitorium in United States only.An additional factor is the  latest AIDS epidemic. AIDS patients are much more likely to develop tuberculosis because of their weakened immune systems. There still are an estimated 8-10 million new cases of TB each year worldwide.\"\"
