Public health impact of detention of individuals with tuberculosis: systematic literature review.

As the world witnesses ever-increasing rates of tuberculosis, particularly of drug-resistant strains affecting some of society's most marginalized individuals, policy makers and legislators may again visit the statute books in order to strengthen their armamentarium of tools to protect public health. This paper assesses the evidence in support of the sanction to detain those with tuberculosis who are perceived as posing a public health threat, and shows that little research has been conducted to inform policy, probably because traditional epidemiological methods used to assess the impact of interventions are not feasible.
