We can't stop the seasonal stomach flu because the stakes are low enough that we aren't handing out hand-sanitizer on every street corner and obsessively quarantining every gastroenteritis sufferer and every person with whom they ever interacted.

flu is airborne. ebola isn't, and no one that i know of at the cdc is seriously considering the possibility that it will become airborne.

Stomach flu isn't flu. Stomach flu is a misnomer, referring to gastroenteritis, a symptom of a stomach bug - generally a virus, but not influenza (the flu). It's relevant because the infectious mechanism of stomach bugs is similar to Ebola - the disease spreads by people interacting with sufferers' copious vomit and diarrhea.
