Risk and Complications

Those most at risk of getting TB include:

  • People who have had close and prolonged contact with someone with active TB disease
  • People who have lived or travelled to areas of the world where TB is common
  • People who have lived on a First Nations reserve or in an Inuit community
  • People who have weakened immune systems that reduce their ability to fight infection
  • People who drink alcohol heavily.
  • People who are homeless or live in shelters and hostels
  • Staff and residents of long-term care facilities, hospitals and correctional facilities
  • People who smoke
    • Smoking may increase the risk of becoming infected with TB by up to three times, and exposure to second-hand smoke increases the risk of becoming infected with TB in both children and adults.
