What Is the Stomach Virus? Stomach flu is caused by a virus. There are a number of different viruses that can cause stomach flu, but the so-called "stomach virus" does not actually affect the stomach at all. Viruses that cause stomach flu affect the small intestine. Furthermore, these stomach flu viruses are not actually flu viruses. The flu virus is the influenza virus. Influenza virus does not cause stomach flu symptoms. Regardless of the inaccuracies of the terms "stomach flu" and "stomach virus," these are the most commonly used terms to describe what healthcare providers call viral gastroenteritis. Specific Facts Regarding the Stomach Virus Rotavirus Rotavirus is the leading cause of stomach flu among children 3 months to 15 months old and the most common cause of diarrhea in children under the age of 5 years. This type of "stomach virus" causes vomiting and watery diarrhea for 3 to 8 days, along with fever and abdominal pain. This stomach flu virus can also infect adults who are in close contact with infected children, but the symptoms in adults are milder (see Adult Rotavirus). In the United States, rotavirus infections are most common from November to April.
Adult Rotavirus: Transmission
Large amounts of rotavirus are shed in the stools of infected people. This contaminated stool can easily spread to hands and objects. Because rotavirus is stable in the environment -- meaning that it can live for a long time outside of a host -- rotavirus transmission can occur quite easily through the following methods:
- Ingestion of contaminated food or water
- Direct contact with contaminated surfaces and then putting the hands in the mouth.
Adults are commonly infected by their children.
Symptoms of Rotavirus in Adults
Most adults who are infected with rotavirus will not develop symptoms of the virus. If rotavirus symptoms do occur, the illness can begin suddenly. Common symptoms of rotavirus in adults include:
- Vomiting
- Upset stomach
- Fever
- Watery diarrhea
- Loss of appetite
- Mucus in stool.
Adult Rotavirus: Treatment
There is no medicine that will kill rotavirus. Therefore, adult rotavirus treatment goals are focused on providing supportive care while the body fights the rotavirus infection. Supportive care refers to treating symptoms, such as dehydration, that can occur as a result of the rotavirus infection.
People who experience rotavirus symptoms usually have them for a couple of days. During this time, rotavirus treatment to relieve symptoms can include:
- Resting in bed
- Drinking plenty of fluids
- Taking medication (such as aspirin or acetaminophen) to relieve fever.
Caliciviruses cause infection in people of all ages. This family of viruses is divided into four types, the noroviruses (see Norovirus)being the most common. It is now thought that at least 50 percent of all foodborne outbreaks of gastroenteritis can be attributed to noroviruses. Norwalk virus is a type of norovirus. People infected with one of these "stomach viruses" may develop vomiting anddiarrhea, fatigue, headache, and sometimes muscle aches.Norovirus symptoms appear within 1 to 3 days of exposure. Adenovirus Adenovirus infections occur mainly in children under 2 years of age. Of the 49 types of adenoviruses, one strain affects the gastrointestinal tract, causing vomiting and diarrhea. Symptoms from this "stomach virus" typically appear 1 week after exposure. Adenovirus infections occur year-round. Astrovirus Astrovirus infects primarily infants, young children, and the elderly. This type of "stomach virus" is most active during the winter months. Vomiting and diarrhea appear within 1 to 3 days of exposure.

A stomach Virus ? Who do put a Stomach Virus in Masha's food at the Olympic Games? Ummm So this Virus might have been the cause of her fail against Serena. There are three solutions which explained Masha's fail at the final: 1) It is the Stomach Virus which caused Masha's fail at the final 2) Serena was over-doped and gave no chance to Masha 3) Masha had a Stomach Virus and Serena was over-doped. I hope Masha will find a solution to kill this Virus.

A source told TENNIS.com that Sharapova first got the virus the night before the Olympic gold medal match, when she was crushed by Serena Williams 6-0, 6-1. Lucky loser Galina Voskoboeva will replace her in the draw. On Tuesday in her pre-tournament press conference, Sharapova said she hadn't lost hope after her quick loss to Serena. The world No. 2 hasn't beaten Williams since 2004 and had only won nine games in their past three contests. "If I sat here and thought there was nothing I could do, that would probably be very disappointing," Sharapova said. "It will motivate me to keep going and keep practicing. There are certainly things I could have done better but she was playing really good tennis." http://www.tennis.com/ar...leid=19108&zoneid=25 This tournament is finish for Masha ! 
"I'd love to open a tennis school for children in my hometown of Sochi." said Sharapova Maria.
