I believe the only thing a hospital can offer is a ventilator -- in the worst cases, the disease slashes your lung capacity and a ventilator will keep you oxygenated.

Hospitals will only help if you feel like you can't breathe (and we do not have anywhere near the amount of ventilators that we'll need for this), so the vast majority of people should self-quarantine, take pain killers for fever and wait for it to pass.
