The IUATLD proposed World Tuberculosis Day on March 24, 1982, in partnership with the WHO to commemorate the 100th anniversary of Robert Koch's discovery of the TB bacillus. WHO officially recognized it as an annual observance around 1996.
Celebrate World Tuberculosis Day on March 24 by raising awareness of this serious global health issue! This day was first observed in 1982 to commemorate the date in 1882 when Dr. Robert Koch announced his discovery of Mycobacterium tuberculosis, which is the bacteria responsible for causing TB. Every year now, people around the world come together to spread knowledge about preventing and treating this disease that still affects millions annually.

WHY THIS DAY MATTERS
World Tuberculosis Day serves as a reminder that despite all our efforts to eradicate it, there remains much more work to be done. It’s an opportunity for governments, health organizations and advocates alike to come together, share best practices and collaborate on ways to accelerate access to TB care, reduce infection rates and increase knowledge about this preventable disease.
World Tuberculosis Day is a day of advocacy, education and commemoration for the millions of people affected by tuberculosis (TB) around the world. The day helps to remind us all that TB continues to be a global health emergency and is something we should never take lightly or ignore.
Tuberculosis is a serious illness that can cause severe health complications if not treated properly and promptly. On World Tuberculosis Day, we recognize the individuals living with TB who are struggling with its effects. We also honor the healthcare providers who work tirelessly to diagnose, treat and support their patients in overcoming this disease.
