The Port of San Francisco said that cruise ships and other vessels are responsible for arranging private transportation and private accommodations on shore for COVID-positive passengers or crew to use for quarantine. They must also have private agreements with medical facilities to treat passengers and crew who need to be hospitalized for COVID.

"These agreements are in place to protect local public resources during the ongoing COVID-19 pandemic.," the port said in a statement.
