Viral Gastroenteritis

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: Studies estimate that 90 000–153 000 children die from rotavirus infection in India each year but these numbers are not based on nationally representative samples. 1 in 82 Indian children dying from diarrhoea before the age of 5 years.

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 research was funded mainly by Fogarty International Centre of the United States National Institutes of Health, the Canadian Institute of Health Research, the International Development Research Centre and the United States Fund for the United Nations Children’s Fund.
