“And if we can stop the transmission, we can stop the disease.”—Dr. Julio Montaner, director of B.C.’s Centre for Excellence in HIV/AIDS, July 19, 2012

At first glance, it seemed wasteful, almost insanely so. After the international AIDS conference in Washington, D.C., last week, health officials from B.C. were trumpeting mass population screening for HIV in their province, and eventually, beyond. According to the media reports, if we could get everyone who has ever been sexually active tested (on a volunteer, not mandatory, basis) it could mean “the beginning of the end” of AIDS.

Of course, there was much overselling in the media—with headlines like: “B.C. aims to end HIV/AIDS with widespread testing“ and “B.C. launches massive program to wipe out HIV/AIDS.” But this screen-everybody approach also seemed dubious from a public health viewpoint. Given the well-known problems associated with over-testing, over-screening, and over-diagnosis in other areas of medicine—from PSA testing to pap smears—why try the catch-all method with HIV? What about the traumas related to false positives and the sheer monetary cost of such an encompassing plan? Plus, Canada doesn’t have a high prevalence of HIV/AIDS. Why would we adopt mass screening for a disease that mainly impacts marginalised or hard-to-reach groups that probably wouldn’t be captured anyway?
