"Lekarz nie zna tego wirusa."

Translation: The doctor does not know this virus.

This is what doctors often refer to as SBI, or, in worse cases, SVBI.

I actually felt that recognise would be better than know in this sentence

Hmm... I see your point, it makes sense. I guess I can add it.

Would "Lekarz nie wie o tym wirusie" also be a correct translation?

[Jellei]

It kinda makes sense, but more like "The doctor doesn't know about this virus", as if he somehow managed to not hear about the coronavirus, as if he wasn't aware of all the pandemic situation. I'm not sure if it's a translation we should accept.
