I just heard that the Celebrity Infinity alaska cruise had the Norwalk virus on the July 16, 2006 cruise. How do I check to see if other infinity alaska cruises this year had the same problem. I called Celebrity and they said they do not have health records of the ship and this was the only case. I am staying in the penthouse on the august 13 cruise and would go nuts after paying a fortune for the tickets if this is an infected ship. I understand that it is caused from unhealthy food handling.
