What are the symptoms of viral enteritis?

Viral diseases cause a lot of trouble and have a significant impact on everyone's body. Among general adult diseases, once viral enteritis occurs, the patient will suffer from long-term diarrhea and even nausea and vomiting. In severe cases, abdominal pain and bloating will occur. Most patients will have continuous bowel movements ranging from 3 to ten times a day, and the color is usually yellow water or rice soup.

(1) The incubation period of common rotavirus gastroenteritis is 1 to 3 days. The severity of the disease varies greatly, with children aged 6 to 24 months having severe symptoms, while older children or adults mostly have mild or subclinical infections. The onset is acute, with vomiting first and diarrhea later, accompanied by mild to moderate fever. Diarrhea occurs ten to dozens of times a day, and the stools are mostly watery or yellow-green loose stools, often accompanied by mild or moderate dehydration and metabolic poisoning.

Some cases often have upper respiratory tract infection symptoms before gastrointestinal symptoms appear. This disease is a self-limiting disease with a course of about 1 week. However, a small number of children still have short-term malabsorption of disaccharides, especially lactose, and diarrhea may persist for weeks or even months in some cases.

(ii) The incubation period of rotavirus gastroenteritis in adults with diarrhea is 2 to 3 days. The onset is acute, and there is usually no fever or only low fever. The main symptoms are diarrhea, abdominal pain, and abdominal distension. Diarrhea occurs 3 to 10 times a day, with yellow watery or rice-soup stools, without pus or blood. Some cases are accompanied by symptoms such as nausea and vomiting. The course of the disease is 3 to 6 days, occasionally lasting more than 10 days.
