Many people are asymptomatic, and not only that, are exposed by others who are asymptomatic. Short of every single human interaction being preceded by a PCR test, the odds are that he eventually would have been exposed.
It is easy to do an at-home nasal swab test when you are infected but before the viral load has gotten to the point of being highly contagious, at which point you think you are negative but really will soon become contagious.
"Reasonable precautions" would have to be very rigorous, and I have to imagine it would be easy to cave and relax precautions as loneliness sets in.
