History of Medicine About a hundred years ago, public health took a visual turn. In an era of devastating epidemic and endemic infectious disease, health professionals began to organize coordinated campaigns that sought to mobilize public action through eye-catching wall posters, illustrated pamphlets, motion pictures, and glass slide projections. Impressed by the images of mass media that increasingly saturated the world around them, health campaigners were inspired to present new figures of contagion, and recycle old ones, using modernist aesthetics, graphic manipulations, humor, dramatic lighting, painterly abstraction, distortions of perspective, and other visual strategies.
