Question 2

if i have latent tb can it become active?

Accepted Answer

Yes: In most individuals, mycobacterium tuberculosis infection (TB) is contained initially by host defenses, and the infection remains latent (asleep, inactive). However, latent infection has the potential to develop into active infection at any time.

Question 3

could latent tb cause one to get sick more often?

Accepted Answer

No: Latent TB has no clinical consequences as long as it remains latent.

Question 4

how is latent tb different biologically from the active tb?

Accepted Answer

TUBERCULOSIS: Latent TB starts as a primary infection.Foci  may leave nodular scars in the apices of one or both lungs. Active PTB or reactivation occurs often in lung apices.Lung lesions are cavitary( with  hemoptysis)  complicated with  pleural effusion or pneumothorax.

Question 5

once you have latent tb, and you were treated and recovered, can you contract tb again after that?

Accepted Answer

Yes: Even if you've had TB and were treated, you can get re-infected via exposure to someone who has TB. Also, there are a lot of strains that r resistant to many current TB antibiotics, so you must be sure your TB was truly cured. I'd consider getting a sputum smear microscopy. Good luck.
