The claim that every human being carries the tuberculosis bacterium is false. Epidemiological data show that while tuberculosis and latent infections affect a significant portion of the global population, the vast majority of individuals do not carry the bacterium.
The claim is a specific, empirical assertion about whether every human carries Mycobacterium tuberculosis. Global epidemiological studies and prevalence data consistently show that infection rates range from roughly 10% to 25% regionally and globally, meaning the vast majority of people do not carry the bacterium. The claim is therefore clearly refuted by the retrieved literature.
