How can tuberculosis be prevented?

For most Canadians, the risk of being exposed to TB is very low. If you have been in contact with someone who has active TB or think you may have, consult your doctor.


If you plan to travel to countries with high rates of TB, visit a health care provider or travel health clinic 6 weeks before you leave. If you believe you are at risk of getting TB, ask about getting a skin test:

  • before your trip
  • after your trip


If you have a job where you could be exposed to TB, your workplace should have:

  • a TB management program or
  • an infection prevention and control program

It should include policies and procedures that:

  • allow people with TB or those who are suspected of having TB to be quickly identified
  • have controls to prevent the spread of the disease
  • follow routine practices and additional precautions by staff
