If I already had COVID-19, am I immune?

Many researchers think that after someone is infected with the coronavirus, there’s a good chance that person won’t get sick from the virus again for some still-undetermined amount of time. That’s based on what scientists know about how most viruses work. Usually, when you’re sick from a viral infection, your body develops antibodies against that virus. The next time you’re exposed to the virus, those antibodies could stop it from turning into a raging illness — though that isn’t always the case.

 

There isn’t concrete evidence that people who got sick once with COVID-19 can’t get sick again because no studies have specifically tested that idea. But virologists don’t think that this virus behaves differently than most other viruses — so people who did get sick are probably protected. The question, though, is for how long: for some viruses, the protection fades after a year or a few years. There aren’t answers to that question yet.

Yes, this is the basic idea and why many are researching for a vaccine.

 

Now is it possible to get sick again? It's against the basic idea but there were few cases reported.

How many of these cases compare to the huge number of people already infected and cured?

Was the 2nd infectious agent the very same as the 1st one?

i have friends who caught the virus more than one time
regarding the severity depends on the viral load and you body immune system reaction to virus
