The virus responsible for Covid-19, acknowledged as a public health threat, has been causing global disease since it was first discovered in December 2019 in China. The CDC (2021) issued a call for action through its Science Agenda for Covid-19 to identify evidence-based interventions for interrupting disease progression in vulnerable populations such as those in emergency shelter settings.

This project focused on Covid-19 and its impact on the homeless population in northwestern Pennsylvania. The theoretical framework was the John Hopkins Evidence-Based Practice Model (JHEBP). A survey collected self-reported data on the practice and barriers to using personal non-pharmaceutical interventions (NPIs). Participants were adults ages 18 and over in one of two emergency shelters on the data collection date.
