I realize corona viruses have been around infecting us poor old humans but not this strain. Of cause people's immune systems will do their thing same as it did back in the days of smallpox, polio etc. Like I said it will be about the numbers.I shouldn't even post this and I don't want to come across as rude but some of this is completely wrong and shows a level of ignorance of the facts, and how the immune system works. Corona viruses are not new. They were first identified in the 1960s. This is simply a new strain of an old virus albeit a more severe one.
See: Coronavirus | Human Coronavirus Types | CDC
If people's immune systems were not able to fight off the virus everyone who has gets it would die. They don't and that is because their immune systems are able to fight off the virus. The people in danger for this virus are people with compromised immune systems, heart disease, diabetes, ect and the elderly, just as with the flu.
