What is TB and how do I get it?
TB bacteria are spread through the air in tiny droplets when a person who is sick with TB in their lungs coughs, sneezes, or speaks.
Source: ShutterstockIf you breathe in these droplets, you may become infected with the TB bacteria without knowing it because you will not feel sick and will not have symptoms. This is called latent TB infection (LTBI). Millions of people in the United States have TB infection, and without treatment, they are at risk for developing TB disease. That is why getting tested and taking medicine for prevention is important.
What are the symptoms of TB?
- Cough lasting three or more weeks
- Coughing up blood
- Losing weight
- Night sweats
Remember, people with latent TB infection do not feel sick and do not have any symptoms.
Who is more likely to become infected with TB?
If you have one or more of the following risk factors, you have a greater chance of getting TB infection:
- Lived or spent time in a country where TB is common
- Lived or spent time with someone with active TB disease
- Lived or worked in a congregate setting (such as a shelter, jail, long-term care or assisted living facility)
- Worked in a healthcare setting
- Homeless, especially within the last two years
- Drug user
- Infant, child, or adolescent who has spent time with an adult at increased risk for TB infection or TB disease
BCG Vaccine Does Not Prevent TB Unlike many vaccines that are very good at preventing disease, the bacille Calmette-Guerin (BCG) vaccine has limited benefits. It prevents the most serious TB symptoms in infants and young children. It does NOT prevent you from getting TB infection if you are exposed, or from developing active TB disease.
