What are the symptoms to look out for?
TB bacteria most commonly grow in the lungs, and can cause the following symptoms:
- a bad cough that doesn't respond to medication,
- weakness or fatigue,
- weight loss,
- loss of appetite,
- night sweats,
- pain in the chest,
- coughing up blood or sputum (mucus from deep inside the lungs), and
- chills caused by a fever.
Anyone can get TB, but people at high risk generally fall into 2 categories:
1. People recently infected with the TB bacteria.
2. People with medical conditions that weaken the immune system, such as HIV and diabetes.
You're at increased risk for being infected if:
- you've spent time with a person with TB,
- you're from a country or have visited areas where TB is very common
- you live or work where TB is more common, such as a homeless shelter, prison, or long-term care facility, or
- you're a healthcare worker who works with clients or patients who are at increased risk for TB.
