There is no need to get so snippy with me 1011. My spouse is a doctor and you very well could have had a virus that you transmitted to other passengers. There are many types of viruses as well as food poisonings. It was wrong of you to self diagnose yourself.
It is upsetting that you think you are more qualified than a person that spends years in medical school, reasoning like that is exactly why ship illnesses spread so quickly.
I am trying not to attack you personally now like you did me, and one thing about internet travel boards is that you are never sure you are talking to.
I do think this thread has been informative though on how others avoid the ship's doctors even when they are ill.
