When a human vomits, the gastric valve, or the valve which controls when food may enter the esophagus and enter the stomach, become irritated or the nervous system causes it to open, even though no food is waiting to enter the stomach. Then, your stomach churns as it always does, except this time, when it churns, its contents travel upwards through the esophagus and into the mouth.

yes. vomit is no longer in the body. stomach acid is a dilution of HCl (Hydro-Chloric Acid) this is what breaks down food. if the food is outside of the body (i.e. vomit) it can spread pathogens, such as salmanilla, Typhoid, and Hepatitus to name a few. the short answer is yes. treat vomit as a dangerous body fluid.
