Gastroenteritis disease is characterized by the appearance of vomits, nausea, diarrhea and consequently, this will turn into dehydration. All these symptoms come from a stomach virus. Many types of virus can do this effect including actino virus, sapa virus, rota virus, Noro virus and the astro virus. All of this one are capable of causing gastroenteritis.
One important thing is to know when it is a bacterial or viral infection. The signs are if diarrhea is watery then it is virus infection but if it is bloody then it is a bacterial infection. Bacterial infections are accompanied by more fevers than viral infections but symptoms vary from person to person so we can not expect to always have bloody diarrhea in a bacterial infection.
Transmission of gastroenteritis comes either from oral or fecal transmission if someone infected goes to the bathroom and does not wash his or her hands will, of course, have some of the viri on its hands and then goes and touches food or water and you go to drink then the virus is inside your body. The bacteria or virus will go into your digestive system and……… watch the video and find more what happens with this disease.

Gastroenteritis, also known as infectious diarrhea, is inflammation of the gastrointestinal tract—the stomach and small intestine. Symptoms may include diarrhea, vomiting and abdominal pain. Fever, lack of energy and dehydration may also occur. This typically lasts less than two weeks. It is not related to influenza, though it has been called the “stomach flu”.
Gastroenteritis is usually caused by viruses. However, bacteria, parasites, and fungus can also cause gastroenteritis. In children, rotavirus is the most common cause of severe disease. In adults, norovirus and Campylobacter are common causes. Eating improperly prepared food, drinking contaminated water or close contact with a person who is infected can spread the disease. Treatment is generally the same with or without a definitive diagnosis, so testing to confirm is usually not needed.
Prevention includes hand washing with soap, drinking clean water, proper disposal of human waste and breastfeeding babies instead of using formula. The rotavirus vaccine is recommended as a prevention for children. Treatment involves getting enough fluids. For mild or moderate cases, this can typically be achieved by drinking oral rehydration solution (a combination of water, salts and sugar). In those who are breastfed, continued breastfeeding is recommended. For more severe cases, intravenous fluids may be needed. Fluids may also be given by a nasogastric tube. Zinc supplementation is recommended in children. Antibiotics are generally not needed. However, antibiotics are recommended for young children with a fever and bloody diarrhea.
In 2015, there were two billion cases of gastroenteritis, resulting in 1.3 million deaths globally. Children and those in the developing world are affected the most. In 2011, there were about 1.7 billion cases, resulting in about 700,000 deaths of children under the age of five. In the developing world, children less than two years of age frequently get six or more infections a year. It is less common in adults, partly due to the development of immunity.
