Which basically means that most casual users of ice will not contract infections, but it is certainly possible with prolonged use.
EDIT: I am not a doctor, this is just from things that i have read in the past.
Nothing against you man, but Id need to see some documentation on that before Id believe it at all.

I smoke every day with a bong with ice in it, and have never had a problem once. Its just as likely that the person inhaled something else, and it was just a coincidence that he had ice in his bong too.

Its just too unlikely that the ice was the actual cause. At best, Id say its possible it was a catalyst involved with the actual problem and helped enable it, but the ice itself just doesnt seem like the culprit.
