Flu-type patients really just need to be kept warm and hydrated and a place to feel awful in. You could stack them, unless they get to a point of needing breathing assistance and specialised nursing, or get better. That type of accommodation is fine, for those in the early or recovery stages. There would be medical assistance for those needing it, though I bet those resources are stretched thin.
But when at home you eat good, hot food and in quarantine you eat bad, cold food and people don't see to your needs which path do you think people will choose?
