This is good, healthcare workers need safe shelter, but homeless Portlanders need safe shelter too. And the City of Portland, Maine closed the Oxford Street Shelter and family shelter to people newly in need.
Other cities are sheltering homeless people hin otel rooms, where quarantines can be maintained, and where transmission of the coronavirus can be mitigated.
Portland has hotel rooms, and Governor Janet Mills has shut down lodging operations (running hotels) except for, among other other needs, sheltering homeless people.
Hotels in Minneapolis/Saint Paul have started sheltering homeless people "in order to remove them from their previous congregate living settings where the spread of COVID-19 would have been more likely."
