It is possible that tuberculosis is transmitted from patients to healthcare workers (HCWs). However, there are few data on this from developing countries. The object of this study was to document the incidence of tuberculosis among HCWs in the Christian Medical College (CMC), Vellore, India during a 10-year period (January 1992-December 2001). Data were collected from records maintained in the staff and students health services of CMC. A total of 125 cases were diagnosed during the period of study. The overall incidence of sputum positive cases was similar to that observed in the general population, during most years. However, it appears that focal outbreaks occur with transmission between HCWs. The chance of developing extra-pulmonary tuberculosis was higher in HCWs compared with the general population.
