The analysis

The claim states that people with latent TB infection can spread TB bacteria to others. However, medical consensus and retrieved literature (such as papers 0 and 3) establish that latent TB infection is characterized by the containment of the bacteria and the absence of active disease symptoms, meaning infected individuals are asymptomatic and non-infectious. Therefore, the claim is refuted by the definition and clinical understanding of latent versus active tuberculosis.
