AbstractThe global COVID-19 pandemic disrupted supply chains across the world, resulting in a critical shortage of personal protective equipment (PPE) for frontline healthcare workers. To preserve PPE for healthcare providers treating COVID-19 positive patients and to reduce asymptomatic transmission, the Department of Bioengineering at the University of Colorado, Denver | Anschutz Medical Campus collaborated with National Jewish Health to design and test patterns for cloth face coverings. A public campaign to sew and donate the final pattern was launched and over 2500 face coverings have been donated as a result. Now that nearly three million cases of COVID-19 have been confirmed in the United States, many state and local governments are requiring cloth face coverings be worn in public. Here, we present the collaborative design and testing process, as well as the final pattern for non-patient facing hospital workers and community members alike.
