World TB Day: Tuberculosis in Alberta
Although tuberculosis (TB) is not as common as it once was in Alberta, delays in finding and treating TB increase its ability to spread. Children are especially vulnerable to seious, life threatening forms of TB.
TB is caused by bacteria (germs) and is spread when a person with TB disease of the lungs coughs the germs into the air. People sharing that air may breathe in the germs and become infected with TB. Once in the body, germs may remain as TB infection or progress to TB Disease. During TB infection, germs are ‘asleep,’ unable to damage the body and spread to others.
If the infection progresses to TB disease, the germs will ‘wake up’ causing damage to the body and can spread to others (if in the lungs). The time frame for progression from infection to disease can take months or years. About 10% of people who acquire TB infection will progress to disease. Health conditions that weaken the immune system, such as other illnesses, increase this risk.
