mild

bzw. mild disease course / course of disease

Super, danke. Auf 'mild' bin ich nicht gekommen.

Thank you too. Yes, 'symptoms' rings a bell now that I read it.

Just to say that "course of disease" and "clinical course" (how the disease behaves over time) are standard medical collocations. Not always the same as "symptoms" at any one time.

I'd suggest "a mild case" (of Covid-19 or whatever). "A mild course of disease" may be used by doctors, but it doesn't sound very colloquial to my ears. FWIW. I don't know who the "audience" is here.

In/With mild cases no hospitalization...

Thank you both. I actually need both, a 'professional' expression and something people would just say in conversation, so this is a really helpful thread.
