World TB Day

World TB Day commemorates the discovery of the tuberculosis (TB) bacterium (Mycobacterium tuberculosis) by Dr. Robert Koch on March 24, 1882. World TB day is commemorated on this date each year to raise awareness among the public and policy makers that tuberculosis remains an epidemic in most parts of the world, and a public health problem in developed countries, causing the deaths of about one and a half million people each year. Koch's discovery opened the way towards diagnosing and curing TB. Progress toward global targets for reductions in TB cases and deaths in recent years has been impressive: TB mortality has fallen over 40 percent worldwide since 1990, and incidence is declining. New TB tools such as rapid diagnostics are helping transform response to the disease.

Although significant advances have been made, much remains to be done. TB diagnosis can be difficult; treatment is lengthy; and new drugs and vaccines are needed.
