The coronavirus from China was cured for the first time, and before that it was always fatal?

I didn’t understand, the first patient was cured, but before that they couldn’t. In this case, the virus is fatal. About 20 people died, 876 became infected. That is, these 876 were doomed to this point, if the virus is deadly, as they say? They cannot cure him, he is mortal ... is it logical? Or is it just that in some cases the body itself copes, although there is no cure? It looks more logical, but it turns out that they write about people as one hundred percent corpses, since they became infected.

The vaccine will be invented quickly
