How does norovirus cause food poisoning?

ANSWER

Norovirus, often called stomach flu, is behind more than half of the foodborne illnesses in the U.S. where the cause is known. Norovirus can sicken you not only through eating contaminated foods, but also through touching doorknobs and other surfaces or having contact with an infected person. You should wipe down the kitchen if someone in your house has it. It typically takes 12-48 hours before you feel sick. Your symptoms may last one to three days.
