That's kind of scary. Don't flus take 3 days to incubate before you start puking?
Influenza (the flu) is a respiratory disease that does not cause vomiting under any circumstances. The "stomach flu" can be one of a few different illnesses, usually food poisoning (but not in this case, if it was as contagious as glowbelly said), that may or may not start doing bad things immediately.
