No big surprise in this study. Gather a large group of sick people (what you expect in a hospital), close all the doors and windows and you get more germs/viruses inside than you have outside.

Wouldn't a better study have been to simply look at the rate of post-op infections in a large sample of hospitals, see if there is a correlation between the age of the hospital and the number of infections. I'm guessing that, although fresh air improves a hospital, the number of years a hospital has been open will also have a significant impact.
