Centers for Disease Control and Prevention's (CDC) Project Firstline is a national training collaborative launched during the COVID-19 pandemic to strengthen infection control knowledge among frontline healthcare workers (HCWs). Project Firstline collaborates with multidisciplinary partners to deliver educational resources and promote engagement on infection control topics for the healthcare workforce. In 2021, Project Firstline expanded its focus to include community colleges, where many HCWs are trained. The initiative brought together faculty from varied healthcare professions in a summer intensive program designed to foster peer-to-peer learning and curriculum review while emphasizing the "why" behind infection control practices. CDC learned from participants about the need for flexible approaches, variation in the perceived value of teaching infection control topics across professions, and importance of employer engagement in student education. Ultimately, this effort emphasized the crucial role community colleges play in fostering a culture of infection control expertise across healthcare professions.
