Coughs and Sneezes Spread Diseases . This catchy slogan, which according to Dhand and Li (2020) finds its origins in the 1918 flu pandemic, emphasizes the most common route of dissemination for respiratory pathogens. For example, Xie, Li, and Liu (2009) noted that a single sneeze has the power to expel as many as forty thousand droplets at speeds up to one hundred meters per second. Once expelled, Stadnytskyi et al. (2020) explained that these droplets initially remain airborne and will then, via Stokes’ law, fall downward and land on nearby surfaces. The following discussion introduces the Infectious Droplet Detection and Identification (IDDI) system that is designed to locate and classify contagious-particle-containing droplets circulating within the air and attached to various environmental surfaces. The unique features of the IDDI system are highlighted, clarifying current limitations, and after motivating its purpose, both the supportive and challenging forces surrounding its us
