Gastroenteritis is an inflammation of gastrointestinal tract that usually presents with abdominal pain, diarrhea, nausea and vomit. In some cases, dehydration and fever may also occur.
The most common causes of gastroenteritis are usually bacterial and viral infections. Each pathogen may manifest major role in different seasons especially in summer that food is usually spoil rapidly. Ingest of low hygienic food increases risk for diseases especially cholera (Vibrio) from seafood, Campylobacter from chicken, and Salmonella from raw eggs. Some pathogens are usually contaminated in water supply including various types of enteropathogenic E. coli (e.g. EAEC, EPEC and O157) and also amoebiasis (Entamoeba histolytica) and dysentery (Shigella). Norovirus, on the other hand, is the most common pathogen in winter that some may call winter vomiting bugs because of severe diarrhea and vomit. In addition to bacteria and virus, protozoa can also cause gastroenteritis for all year.
