Where'd you get that information?? We've certainly had our share of URI's come in our hospital, and unless they are getting re-infected or they have other health issues (ie. leukemia, FIV etc) it's rare that more than two rounds maximum of antibiotics are required, and the vast majority of them may never have problems again.
