It'd be shocking to say the least, the only Olympics that have been skipped in the modern era were '16, '40 and '44 and that's because there were the World Wars going on at the time. The closest I think we've gotten to a similar scare would be SARS on 2002 but that was just starting iirc when the winter games in Salt Lake City started.
