Feedback:
People with inactive or latent TB have no symptoms and do not feel sick. The transmission of the infection occurs when an uninfected person inhales infected airborne particles that are exhaled by an infected person. Primary infection occurs 6 to 8 weeks after exposure. The patient has a mild, pneumonia-like illness that often is undiagnosed. Active tuberculosis is a result from reactivation of a latent infection.
