In brief: A dormant infection
Latent TB is when someone gets TB and the body is able to suppress the infection but not fully get rid of the organism. They are then "dormant".
When your immune system gets compromised or weakened the infection can "wake up" and reactive and become active again.

In brief: You inhaled it
You inhaled it but do not have the disease.
Check with your doc and protect yourself, usually with nine months of isoniazid.
