Viral Gastroenteritis (Stomach Flu)
Viral gastroenteritis is an intestinal tract infection marked by watery diarrhea, abdominal cramps, nausea or vomiting, and in some cases fever.
The most typical way to develop viral gastroenteritis– typically called stomach flu– is from contact with an infected individual or by ingesting polluted food or water. If you’re otherwise healthy, you’ll likely recover without complications. But for infants, older adults and individuals with compromised body immune systems, viral gastroenteritis can be lethal.
There’s no reliable treatment for viral gastroenteritis, so prevention is essential. In addition to preventing food and water that may be contaminated, thorough and frequent hand-washings are your best defense.
Viral gastroenteritis (stomach flu) symptoms
Although it’s typically called stomach flu, gastroenteritis isn’t the like influenza. Real flu (influenza) impacts just your respiratory system– your nose, throat and lungs. Gastroenteritis, on the other hand, attacks your intestinal tracts, causing symptoms and signs, such as:
- Watery, generally nonbloody diarrhea– bloody diarrhea typically suggests you have a various, more severe infection
- Abdominal cramps and pain
- Nausea, vomiting or both
- Periodic muscle aches or headache

Depending on the cause, viral gastroenteritis symptoms may appear within one to three days after you’re infected and can vary from mild to severe. Symptoms typically last just a day or two, however occasionally they may persist as long as 10 days.
Due to the fact that the symptoms are comparable, it’s easy to confuse viral diarrhea with diarrhea caused by bacteria, such as Clostridium difficile, salmonella and E.coli, or parasites, such as giardia.

A number of viruses can cause gastroenteritis, including:.
- Noroviruses. Both children and adults are impacted by noroviruses, the most common cause of foodborne illness worldwide. Norovirus infection can sweep from households and communities. It’s specifically most likely to spread out amongst individuals in restricted areas. In many cases, you get the virus from contaminated food or water, although person-to-person transmission also is possible.
- Rotavirus. Worldwide, this is the most typical cause of viral gastroenteritis in children, who are usually infected when they put their fingers or other things infected with the virus into their mouths. The infection is most severe in infants and little ones. Adults infected with rotavirus may not have symptoms, however can still spread the illness– of specific issue in institutional settings because infected adults unwittingly can pass the virus to others. A vaccine against viral gastroenteritis is offered in some nations, including the United States, and appears to be reliable in avoiding the infection.
- Some shellfish, especially raw or undercooked oysters, likewise can make you sick. Although polluted drinking water is a cause of viral diarrhea, in many cases the virus is passed through the fecal-oral route– that is, somebody with a virus deals with food you eat without cleaning his/her hands after using the toilet.
Complications: Is It Dangerous?
The primary problem of viral gastroenteritis is dehydration– a severe loss of water and important salts and minerals. If you’re healthy and drink enough to change fluids you lose from vomiting and diarrhea, dehydration shouldn’t be a problem.
Infants, older adults and individuals with reduced body immune systems may end up being significantly dehydrated when they lose more fluids than they can change. Hospitalization might be needed so that lost fluids can be changed intravenously. Dehydration can be deadly, but hardly ever.
Treatments for viral gastroenteritis (stomach flu)
There’s frequently no particular medical treatment for viral gastroenteritis. Antibiotics aren’t effective against viruses, and overusing them can contribute to the development of antibiotic-resistant stress of bacteria. Treatment at first includes self-care procedures.
Lifestyle and home remedies
