The period between exposure and infection is called 'latent period', since the pathogen is present in a 'latent' stage, without clinical symptoms or signes of infection in the host. Because the viral genetic material can then be replicated along with the host material, the virus becomes effectively "silent" with respect to detection by the host. 70%~90% of people that come into contact with TB bacteria will fight off the disease with their own body's immune system but 10%~30% of the time, the immune system will contain the bacteria, turning it into Latent TB.
