I wonder if there's extra selective pressure among relatively smart creatures like us. Supposing there's a really nasty disease that manifests after a week, and we're contagious for a few days before. Eventually we'll get wind of it and start being more careful. If it's a less nasty virus, we just won't care enough and let it spread.
