World TB Day is a day to bring public awareness on TB, the deadliest infectious disease in the world. It is held every year on March 24th, to commemorate the day Dr. Robert Koch announced the discovery of mycobacterium tuberculosis, the bacteria that causes TB. World TB Day is a day to acknowledge the presence of the disease and increase efforts to eliminate it.

Each year on World TB Day, the Los Angeles County Department of Public Health Tuberculosis Control Program conducts special activities to bring awareness to TB.

This year, in 2025, our program:

• Participated in the global “Light Up the World” campaign by lighting Los Angeles City Hall and Union Station in red, the symbolic color of TB.
  
  
• Collaborated with the Los Angeles County Board of Supervisors to pass a motion to Proclaim March 24th as World Tuberculosis Day in Los Angeles County.
  
• Collaborated with the City of Beverly Hills to recognize March 24th as World TB Day.
  
• Participated in a TB testing outreach event in Service Planning Area 2 on March 6, 2025.
