A clinical syndrome characterized by acute infectious gastroenteritis with watery diarrhea, vomiting, malaise, and abdominal cramps with a relatively short incubation period (12–36 h) and duration (24–48 h). A viral etiology is suspected when bacterial and parasitic agents are not found. In the United States, no etiologic agent can be found in 70% of the outbreaks of gastroenteritis. Most of these may be due to viral agents, such as the Norwalk, Snow Mountain, and Hawaii agents, astroviruses, caliciviruses, adenoviruses, nongroup A rotaviruses, and paroviruses. Epidemics are common worldwide and have occurred following the consumption of fecally contaminated raw shellfish, food, or water, although the virus may be spread by airborne droplets as well. Epidemics are most frequent in residential homes, camps, institutions, and cruise ships. Many individual cases of mild diarrhea may in fact occur in epidemics for which the source of the infection cannot be found. Epidemic viral gastroente

Winter Epidemic of Viral Gastroenteritis

Norovirus is one of the frequent causes of a seasonal rise of viral gastroenteritis in Hong Kong during September through December. Norovirus is occasionally mentioned as “winter vomiting disease”.  Two different epidemiological patterns are winter vomiting disease most prevalent. The first type of winter vomiting disease is transmitted and mainly affects adults, and frequently associated with eating up undercooked bivalve shellfish like raw oysters. The second type is spreads person-to-person. After the incubation period is completed, a vomiting incident is started followed by an acute gastroenteritis among patients. This type is more commonly found among attendees and residents of schools and nursing homes. Some viruses like rotavirus, enteric adenoviruses, astrovirus, and sapovirus have been proved to be as agents of acute viral gastroenteritis. These gastroenteritis agents are frequently cause intermittent diarrheal infections and are fewer connections with epidemics. Rotavirus is

Drinking Water Guidelines - Dehydration

The U.S. National Research Council advises that 1 mL of water for every calorie is advisable. Therefore, person who consumes 2,000 calories a day should be drinking 2,000 mL of water/fluids. Other suggestions include fruit juice, soda, ice tea, caffeinated beverages, like coffee, tea, and green tea. It is also advisable to drink more water while exercising and in hot weather. Drink an extra quart of water every hour of exercise. Avoid drinking before sleeping at night: To drink water in the evening may cause waking up during the night to urinate, consequently an uncomfortable sleep at night. Avoid drinking at least two hours before bedtime. Drink Filtered Water Drinking water can be contaminated with heavy metals, microorganisms, chlorine, fluoride, and other impurities. Therefore use of reasonably priced water filter on the market, such as Brita or PUR is advisable. Quality of drinking water can also be improved by filtering it with a reverse osmosis mechanism, charcoal, ceramic,

Treatment of Travelers' Diarrhea

You may have severe travelers' diarrhea if you have three or more loose stools in 8-hours along with cramping, nausea and vomiting, bloody stools, or fever. Travelers' Diarrhea is treated through Oral replacement therapy (ORT). In this therapy body fluids are replaced through ORS. If ORS is not available, drink water along with salty crackers. You can also make your own ORS by mixing one liter of water with 6 level teaspoons of sugar and 1 level teaspoon of salt. A combination of ORS and anti-motility medications and/or antibiotics is recommended. Treatment for Severe Travelers' Diarrhea The travelers' diarrhea should be treated with ORS and medicines like fluoroquinolone antibiotic, (e.g., Noroxin® or Cipro®). Imodium® AD or Lomotil® may be used in conjunction with the antibiotic as explained below, if the fever or bloody stools are not present. If possible, seek physician advice for severe travelers' diarrhea rather attempting self-medication. Absorbents: Absorben

Mucus in Stool - Symptoms and Remedies

The presence of Mucus is to ease Bowel Movement out of our bodies. Mucus membrane of large intestine produces a clear, white, or yellow jelly like substance, Mucus. Other organs of the body such as lungs also produce Mucus. In intestines, the prime object of mucus is to protect inner lining of the intestine and to ease the passageway of stool. The following some reasons associated with prevalence of mucus in stool:- Irritable Bowel Syndrome during Ulcerative Colitis As already written, mucus is a normal function of intestines for smooth passage of stool when produced in a reasonable amount. But in IBS, mucus production is increased by the lining of the intestine. Mucus membrane of the intestine develops inflammation and become ulcerative. The ulcerative intestine then starts bleeding and produces pus and mucus. Mucus is often connected with diarrhea-predominant IBS. Mucus is not as recurrent as with Crohn's Diseases (CD), but can be related with the development of an anal fissure
