The homeless community is society’s most vulnerable group because they do not have access to the same hygienic indoor spaces, or sanitation that the housed have access to. Homeless persons die from illnesses that can be treated or prevented. Crowded, poorly-ventilated living conditions, found in many shelters, promote the spread of communicable diseases. Federal, State/Provincial and Municipal governments should be investing in disinfecting our shelters with UV-C. Let’s do more to protect the unhoused, and mitigate the spread of disease by mass deploying enclosed UV-C, or Far UV upper room lighting devices to our homeless shelters.
