Oh definitely. I think that I may have had it near the start of the pandemic (fatigue/flu like symptoms for a few weeks) but my wife didn't have any antibodies (but I did wear a mask everywhere for the first while I had symptoms). It's a very odd disease in terms of spread, there's super high variance in transmissibility.
