Syphilis is a disease caused by the spirochetal bacterium Treponema Pallidum subspecies pallidum. The route of transmission of syphilis is almost always through sexual contact. The incidence of syphilis decreased significantly with the introduction of penicilin in the 1940s but rose sharply again with the advent of HIV infection in the 1980s. https://www.roneverhart.com/Bauhaus-Design-Stencil/
