Letter to the Editor
The risk of tuberculosis (TB) transmission to healthcare workers (HCWs) is well known and was recently reviewed in low and high incidence countries. TB infection control programmes in healthcare settings that include evaluation of latent TB infection (LTBI) in HCWs are recommended.3 Few studies have evaluated the risk of TB infection among healthcare students. We conducted a study in Rio de Janeiro State, Brazil, to evaluate recently acquired LTBI among undergraduate medical students in three cities with TB incidence rates of 28, 63 and 114 per 100 000 inhabitants.
