Rotaviruses, noroviruses, adenoviruses, and astroviruses are known to cause viral gastroenteritis. [26] Rotavirus is the most common cause of gastroenteritis in children, [25] and produces similar rates in both the developed and developing world. [20] Viruses cause about 70% of episodes of infectious diarrhea in the pediatric age group. [13]
Most children admitted to hospital with gastroenteritis are tested for rotavirus. [95] [96] Specific diagnosis of infection with rotavirus is made by finding the virus in the child's stool by enzyme immunoassay. There are several licensed test kits on the market which are sensitive, specific and detect all serotypes of rotavirus. [97]
Norovirus is a leading cause of acute gastroenteritis, ... viral or bacterial," says Hayes. ... dry mouth, or dizziness, per the CDC. Signs in children include crying without tears, becoming fussy ...
Human astroviruses are associated with gastroenteritis in children and immunocompromised adults. [32] 2–8% of acute non-bacterial gastroenteritis in children is associated with human astrovirus. These viral particles are usually detected in epithelial cells of the duodenum. [4]
Symptoms of norovirus can vary from person to person, but they generally include lots of gastrointestinal discomforts and inflammation of the stomach and intestines (gastroenteritis), according to ...
Sapovirus is a genetically diverse genus of single-stranded positive-sense RNA, non-enveloped viruses within the family Caliciviridae. [1] [2] Together with norovirus, sapoviruses are the most common cause of acute gastroenteritis (commonly called the "stomach flu" although it is not related to influenza) in humans and animals.
The norovirus was originally named the "Norwalk agent" after Norwalk, Ohio, in the United States, where an outbreak of acute gastroenteritis occurred among children at Bronson Elementary School in November 1968. In 1972, electron microscopy on stored human stool samples identified a virus, which was given the name "Norwalk virus".
Antibiotics will not be effective if the cause of gastroenteritis is a viral infection. Doctors usually do not recommend antidiarrheal medications (e.g., Loperamide) for gastroenteritis because they tend to prolong infection, especially in children. [2] Parasitic infections are difficult to treat. A number of drugs are available once the ...
