After hearing that brief description, I think I'm better off not knowing!

maybe you can learn more. There's quite a bit to read from.
From Wikipedia:
Noroviruses are a genetically diverse group of single-stranded RNA, non-enveloped viruses in the Caliciviridae family.[1] The viruses are transmitted by fecally-contaminated food or water; by person-to-person contact;[2] and via aerosolization of the virus and subsequent contamination of surfaces.[3] Noroviruses are the most common cause of viral gastroenteritis in humans,[4] and affect people of all ages.[4]
Norovirus infection is characterized by nausea, forceful vomiting, watery diarrhea, and abdominal pain, and in some cases, loss of taste. General lethargy, weakness, muscle aches, headache, coughs, and low-grade fever may occur. The disease is usually self-limiting, and severe illness is rare. A small number of people die, mostly the very young, elderly, and persons with weakened immune systems.
Winter vomiting bug is a common term for noroviruses in the UK, because the virus tends to cause vomiting and to spread more easily in winter, when people tend to spend more time indoors and near to each other.[5]
After infection, immunity to norovirus is usually incomplete and temporary.[6] Outbreaks of norovirus infection often occur in closed or semiclosed communities, such as long-term care facilities, overnight camps, hospitals, prisons, dormitories, and cruise ships, where the infection spreads very rapidly either by person-to-person transmission or through contaminated food.[7] Many norovirus outbreaks have been traced to food that was handled by one infected person.[8]
Norovirus is rapidly inactivated by either sufficient heating or by chlorine-based disinfectants, but the virus is less susceptible to alcohols and detergents, as it does not have a lipid envelope.[9]
The genus name Norovirus is derived from Norwalk virus, which causes approximately 90% of epidemic nonbacterial outbreaks of gastroenteritis around the world,[10] and may be responsible for 50% of all foodborne outbreaks of gastroenteritis in the United States
