3. How the Stomach Flu Spreads

You can get viral gastroenteritis from airborne droplets of vomit containing viral particles, contaminated surfaces, or consuming contaminated food and water. Common foods linked to outbreaks are leafy greens, fresh fruits, and shellfish. The flu spreads very quickly between people. Norovirus is extremely stable in the environment; it can resist freezing temperatures, heating to 140 degrees and disinfection with chlorine or alcohol. Norovirus caused almost half of more than 2000 foodborne outbreaks between 2009 and 2012.
