Auschwitz Birkenau The Nazis set up a number of "Hospitals" or "infirmaries" witthin the camp. Auschwitz I had "block 19, the Schonungsblock for convalescent prisoners; block 20, the contagious diseases block; block 21, the surgical block; and block 28, the internal medicine block." In reality of course the "treatment" included medical experimentation and selection for execution. Insofar as it existed at all it was aimed at "reducing the prisoner death rate—in relation to prisoners who seemed likely to return to labor in a short time." See ; link
