But what people (and the CDC and WHO) are trying to tell you is no further concern is necessary at this time.
Unless you were on the ship or in direct contact with someone who was, you are at "low risk", and no special precautions are necessary.
So, that being said, what exactly would you like the CDC/WHO to say?
OP - I think the above poster pretty much nailed it on the head, you want the safety officials, entities and governments to give you direction. They have, yet you would rather disregard other posters providing you the exact info you requested in the form of links and statements in favor of whatever this is ... I don't understand your angst, but I hope you get it resolved.
I'm glad your daughter is going to Spain, I hope she had a great time and really enjoys herself. And as a capable adult you realize she can take care of herself, read up on appropriate precautions when necessary and is prepared.
