Unnecessary exposure?
=====================

* Steven L. Shumak

In the informative article by Mithu Sen and colleagues1 concerning neonatal exposure to active pulmonary tuberculosis, some very revealing, and I think irrelevant, details were provided about the index case. The reader learns not only this man's age and occupation, but also his ethnicity, immigration history and specific place of employment. Some of those pieces of information, by themselves, could have led to the identification of the subject. When taken together, they leave no doubt.

Would the scientific value of the article have been compromised by simply stating that this man had emigrated from an area where tuberculosis is prevalent? Would the public health implications have been any less significant had the subject been referred to as a „health care professional working in the neonatal intensive care unit?”

I presume that the physician described in this report gave written consent (as is *CMAJ*'s policy for such matters). Even so, I see no reason why his identity had to be made so transparent.
