Kind of. It's certainly true that rain does not manufacture bacteria and viruses on its way down; the idea that being in the rain will cause you to come down will cause you to be infected with them is an idea that would be evidence of stupidity if it wasn't so prevalent as to be ingrained in one's head from such an early age, it takes a conscious relevation to kick it.

On the other hand, exposure to cool dampness weakens one's natural defense against catching something or other, and dampness is more conducive to transmitting bacteria than dryness. (Pneumonia isn't out of the question either; prolonged exposure to coolness and dampness can do just that -- but you'd essentially have to be out far longer than would be comfortable for that to be a danger.)

In today's modern medical age, where diseases don't run so rampantly and cold aren't so serious in the first place, this is a caveat I would give no consideration to whatsoever. As long as you make sure you get warm and dry when you come in, there won't be any health problem there wouldn't have been otherwise.

So, yeah, it's annoying, and I hate it, too.
