I don't think current precautions are incongruous with the past. Because they are significantly different situations.
(Edit: Removed "inappropriately" from "incongruous", as it was intended to clarify but it proved unhelpful. Keeping this note because it gives context to the reply.)
I think comparing two situations and calling the different responses to them "incongruous" implies the comparison is intended to be about something you think is appropriate. (And I think it's an inappropriate comparison, because Covid and flu are sufficiently different.) Otherwise the comparison is pointless. Perhaps I should have written "appropriately incongruous" instead of "inappropriately", though; the multiple negatives seem to get confusing around that sort of language, especially across continents.
So your partner did not quarantine? Avoid non-essential trips? Wear a mask?
I don't think you'd disagree that our COVID precautions at _this_ point are incongruous with the past, but highlighting it for others reading.
