Mpox is a new public health outbreak that particularly threatens the homeless population. Street Medicine Phoenix (SMP) is a student-led interprofessional volunteer organization that provides medical care and other essential services to individuals experiencing homelessness in Phoenix, Arizona. In addition to core services such as wound care; health screenings (blood pressure and blood glucose.); vision screenings; HIV testing; naloxone education and distribution; flu, COVID-19, and Hepatitis A vaccinations; and community resource referrals, SMP began offering mpox education and vaccination at outreach events. During an outreach event shortly after the onset of the mpox outbreak, SMP identified 2 suspected mpox cases. Accordingly, SMP has partnered with the Maricopa County Public Health Department to set up mobile mpox vaccination clinics on the streets outside of Phoenix Arizona’s largest homeless shelter. We share the details of these 2 cases along with our early efforts vaccinating individuals experiencing homelessness for mpox via our mobile vaccination clinic. Our experiences demonstrate the importance of community agencies providing direct outreach to underserved populations where they are at, particularly the homeless population, to address public health concerns such as emerging disease outbreaks like mpox. In addition, these cases highlight the potential significant impact that street medicine programs can have on their respective homeless communities in the context of infectious disease mitigation and emphasize the importance of partnerships with local health departments.
