The two types of Tuberculosis (TB) are TB disease and latent TB infection.
Here's a breakdown of each type:
- TB Disease: This is the active form of TB. People with TB disease usually have symptoms and can spread TB germs to others.
- Latent TB Infection (LTBI): In this state, TB bacteria are present in the body but are inactive. People with LTBI do not feel sick, do not have symptoms, and cannot spread TB germs to others. However, without treatment, LTBI can progress to TB disease.
In summary:
| Feature | Latent TB Infection (LTBI) | TB Disease |
|---|---|---|
| Symptoms | No | Yes |
| Infectious | No | Yes |
| Feels Sick | No | Yes |
| Can Spread TB | No | Yes |
| Bacteria Status | Inactive | Active |
| Treatment Needed | Often, to prevent disease | Always |
