How does a corona virus infection go?

There's a lot of fuss in the media right now because of the "corona virus", but nowhere else can I find information on how an infection would proceed.

What symptoms appear when, what are the stages of the disease and how long is the approximate duration of the disease? After getting through the infection, are you immune to the current form of the virus? Google only spits trash.

I'm worried that I'm exposed to an increased risk of infection in the gym because there's a high migration rate in the studio with a particularly large number of Asian-looking people.

If your immune system is normal you don't need to worry about it

I'll tell you something crazy, Italians could also infect you.
