Homelessness and COVID-19: Leaving No One Behind

The United Nations 2030 Agenda for Sustainable Development promotes the "Leaving no one behind" principle and sets goals in areas of critical importance. This principle has become extraordinarily important during the COVID-19 pandemic, and is especially relevant for fragile populations, such as people experiencing homelessness. Homeless persons live in congregate and poor hygiene settings that may favor virus transmission, often have underling physical and mental comorbidities that place them at high risk of severe forms of COVID-19, and have limited access to public healthcare and social services. In addition, the homeless are often overlooked by safety and health monitoring actions. All of these factors, taken together, place homeless persons at high risk of being left behind. It is therefore of utmost importance to put in place adequate public health measures to limit spread of infection among homeless persons, rapidly identify and isolate asymptomatic and minimally symptomatic subjects, promptly and appropriately treat positive cases, and correctly handle the entire socioeconomic environment of vulnerable people.
