If you have nausea, forceful vomiting, watery diarrhea, abdominal pain, muscle aches, headache, coughs, then don't go to the super bowl

Noroviruses are a genetically diverse group of single-stranded RNA, non-enveloped viruses in the Caliciviridae family.

The viruses are transmitted by fecally-contaminated food or water; by person-to-person contact and via aerosolization of the virus and subsequent contamination of surfaces.

Noroviruses are the most common cause of viral gastroenteritis in humans, and affect people of all ages.

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.

A new strain of the highly contagious norovirus is in the United States from Australia.

The U.S. Centers for Disease Control and Prevention (CDC) reports that the virus, named GII.4 Sydney because it's believed to have started in Sydney, Australia, is currently the leading cause of norovirus outbreaks in the United States.

A new strain of norovirus known as Sydney 2012 has caused a significant number of acute outbreaks of the infection during the 2012-2013 winter season and continues to spread worldwide.

Writing in the Morbidity and Mortality Weekly Report, published by the Centers for Disease Control and Prevention (CDC) in the USA, Eyal Leshem (CDC, Atlanta, Georgia, USA) and colleagues report that the GII.4 Sydney 2012 strain of the virus has taken over as the most dominant strain in the US this season, being responsible for 53% of all reported cases in the September-December 2012 period.
