Pathophysiology: Viral gastroenteritis is an intestinal infection where inflammation of the stomach and intestines occur from a virus. It is also known as “stomach flu”. This infection may lead to watery diarrhoea, abdominal cramps, nausea or vomiting, and fever. It occurs by contact with a diseased person or by intake of contaminated food or water.Clinicians have categorized it into: Sporadic gastroenteritis, Epidemic gastroenteritis (food-borne or water-borne pathogens), and Acute gastroenteritis.
Disease Statistics: As per the statistics of 2010, the rate of acute gastroenteritis is increasing dramatically to 26 per 1000 per annum in China. All of the norovirus strains belonged to GII genogroup including GII.3, GII.4 and GII.6, of which GII.4 (61.2%) was the predominant genotype. Higher rates of norovirus infections were detected from September to November.
Treatment: Viral gastroenteritis is diagnosed by physical exam such as stool sample to test for virus. There are no specific medical treatments and initially it involves lot of self-care measures. Antibiotics aren?t effective against viruses. The illness may be due to parasitic or bacterial infection. Primary goal is to prevent dehydration by providing enough water and fluids to the diseased body. Food is offered in small amounts. In case of small children, food is supplied intravenously.
Research: The major research on viral gastroenteritis is supported by by grants from the Natural Science Foundation of Shandong Province, National Key Programs for Infectious Diseases of China and the Public Welfare Research Programs of Technology Application of Huzhou.
