It's Possible: Vomiting itself is not contagious. However, it is possible to spread a bacteria or virus that causes vomiting. In this case, whether or not it is contagious depends on the bacteria or virus being passed. In order to determine the cause of your vomiting and whether or not it is contagious please see your primary care physician.

Depends: Vomiting is a symptom of an illness and is not itself contagious. If you have a viral or other infectious cause of the vomiting, then there is a possibility of spreading this infection.
