If the rate of infection is uncontrolled, if we do nothing and behave normally the horror will visit us. The horror is we must choose to save someone and at the same time let others die. The life saving supplies, facilities and personnel will have to be rationed out.
Outbreaks like this will last for months. Making life and death choices and seeing deaths up close is not something we want to deal with. Triage means you try to save lives very quickly by prioritizing multiple victims. If you can save one but it will take time and supplies you don’t have. You let them die.
We don’t see it. But it happens. It could be worse if we don’t change our behaviors.
