Here are two posts I made over on the cruise critic boards. Again, I did some research and Ive decided FOR ME, what Im doing. Im not going all chicken little and freaking out, I just figured if I was going to bring something such as wipes or hand sanitizer, it was probably best to get one that kills noro and Im convinced that purell does not
I did a little looking around today, and I found that the Purell hand gel does NOT kill the Norovirus, which is most likely what people might get on a cruise. BUT, theres a chemical that does, its called benzylkonium chloride. Germex Wipes in the round pop up container have it (but the single packs do not!) and theres some little spray version of it, called Soapopular that
Walmart sells, but I couldnt find it. My issue was trying to find something with that in it that was small, portable and not over 3 oz since we are not checking bags on the plain. I got little 1.7 spray bottles of something called Kids Smooth and Silky Alcohol free hand sanitizer. Its a spray, but turns into a foam, apparently this benzyl whatever doesnt come in a gel. I found it at Target. So now I have the wipes, so I can wipe down things if I want, and the little spray bottles for hands. Im assuming whatever kinds of sanitizer wipes or pumps they have on teh ship are the kind that kill the noro, but in case anyone wanted to get some of this stuff, this is what I found.
2nd post (after someone asked me where I had found the information)
Just going by a few things I read. The first is wikipedia, now I know anyone can edit that, but this article has some good cites and it says right in it that alcohol santizer gels are not very effective in combating Norovirus and the cite for that opinion is an article from the American Journal of infection control. Im not well versed enough to completely understand and debate it, but I did see several other links that specifically say benzylkonium chloride DOES kill noro, and most other things too, so I made the decision to go with that. Heres the link from wikipedia and a few others I found.

This link shows that GoJo, the company that makes Purell has now come out with a new product that is effective against Noro, since previous alcohol based products were not. If regular purell killed noro, why the need to come out with something different?

The link below is admittedly a press release from a company who claims to make a product with benzylkonium chloride that DOES kill noro, but I would think they could not come right out and say that if it didnt really do it.

This link below seems to be a fairly unbiased study done, and I fully admit I dont understand ALL the science, but it does suggest that strictly alcohol based hand gels are not that effective against noro.

And lastly this link, again from a company that makes benzylkonium product, but it does cite actual studies. Alcohol based gels alone just dont seem to be effective enough in killing noro. Thats my opinion based on some pretty good research, not just internet sales sites.
