I have e-mailed the company to check that the Virusan hand sanitisers definitely kill noro- will pass on what they tell me. Also check out Newgenn Ltd- their foam handwash- (they also sell foam hand sanitisers) which is what I use at home is recommended by Virusafe which is the company that the links are from, who also sell products (Virusolve, Virusan etc) that claim to kill noro. Just have a nosy round and see what you think. Be warned the links may lead you to articles etc that use words like v* etc.
This is a UK based website but they mention quoting costs for international deliveries. Hope it may help, I'm going to have a good look around.
