5 FAQs About Tuberculosis
Here are 5 frequently asked questions about Tuberculosis (TB) along with detailed answers:
1. What is Tuberculosis and how does it spread?
Tuberculosis is a serious infectious disease caused by bacteria called Mycobacterium tuberculosis. It typically affects the lungs, but can spread to other parts of the body. TB spreads through the air when an infected person coughs, sneezes, sings, or talks. You can inhale the bacteria and become infected if you’re in close contact with someone who has active TB. It’s important to note that TB cannot be spread by casual contact such as shaking hands or sharing utensils.
2. Who is at risk of getting TB?
Anyone can get TB, but certain factors increase your risk. These include:
- Close contact with someone infected with active TB: Spending extended time around someone with active TB significantly raises your risk.
- Weakened immune system: Conditions like HIV/AIDS, diabetes, or long-term steroid use can weaken your immune system, making you more susceptible to developing active TB from a latent infection.
- Certain behaviors: Intravenous drug use can damage the lungs and increase TB risk.
- Age: Children under five and older adults are more vulnerable to developing active TB.
- Living conditions: Overcrowding and poor ventilation can increase the risk of transmission.
3. What are the symptoms of TB?
People with latent TB infection have no symptoms and aren’t contagious. However, if the infection becomes active, symptoms may include:
- Persistent cough (lasting more than 3 weeks)
- Fever
- Night sweats
- Unexplained weight loss
- Fatigue
- Loss of appetite
- Chest pain (with coughing or breathing deeply)
If you experience these symptoms, it’s crucial to see a doctor to get tested for TB. Early diagnosis and treatment are essential.
