Dr. Elena M. Andresen, a professor emerita from Oregon Health and Sciences University, details that one of the main sites of friction between public health and disability studies is the differing view of prevention work between the two fields. Andresen notes that in disability studies literature prevention is often presented akin to eugenics in preventing the existence of people with disabilities - whereas folks in the Public Health field view prevention through the lens of preventing the incidence and severity of an injury or condition, public health does not consider disability selective abortion or euthanasia as part of public health work but it is easy to see the slippery slope from preventing incidences and severity to preventing disability.
