# Know For Sure

A Hollywood-produced melodramatic short that deals with prophylaxis, diagnosis and clinical treatment of syphilis. Discusses follow-up treatment, sources of infection and community control. Unfortunately, this is edited version which is missing the graphic syphilis sores on male genetalia and the demonstrations on how to use condoms. (I say "unfortunately" because those scenes give the film a different tone than the milder version you'll see here. Still looking for a full copy of original version.)
