World Tuberculosis Day 2022: 24 March

World Tuberculosis Day is observed every year on 24 March to create awareness among the public about the global epidemic of tuberculosis (TB) and efforts to eliminate the disease.

The theme of World Tuberculosis Day 2022 is ‘Invest to End TB. Save Lives’.

The date marks the day in 1882 when Dr. Robert Koch announced he had discovered the bacterium that causes tuberculosis, which opened the way towards diagnosing and curing this disease.
