Adenovirus: A group of viruses responsible for a spectrum of respiratory disease as well as infection of the stomach and intestine ( gastroenteritis ), eyes ( conjunctivitis ), and bladder ( cystitis ) and rash . Adenovirus respiratory diseases include a form of the common cold , pneumonia , croup , and bronchitis . Patients with compromised immune systems are especially susceptible to severe complications of adenovirus infection. Acute respiratory disease (ARD), a disorder first recognized among military recruits during World War II, can be caused by adenovirus infections under conditions of crowding and stress.

CDC: The Centers for Disease Control and Prevention , the US agency charged with tracking and investigating public health trends. The stated mission of the CDC is "To promote health and quality of life by preventing and controlling disease, injury, and disability." The CDC is a part of the U.S. Public Health Services (PHS) under the Department of Health and Human Services (HHS).

Dehydration : Excessive loss of body water. Diseases of the gastrointestinal tract that cause vomiting or diarrhea may, for example, lead to dehydration. There are a number of other causes of dehydration including heat exposure, prolonged vigorous exercise (e.g., in a marathon), kidney disease, and medications (diuretics).

Diarrhea : A familiar phenomenon with unusually frequent or unusually liquid bowel movements, excessive watery evacuations of fecal material. The opposite of constipation . The word "diarrhea" with its odd spelling is a near steal from the Greek "diarrhoia" meaning "a flowing through." Plato and Aristotle may have had diarrhoia while today we have diarrhea. There are myriad infectious and noninfectious causes of diarrhea.

Disease: Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.
Escherichia coli: Full term for E. coli, the colon bacillus.

Fever : Although a fever technically is any body temperature above the normal of 98.6 degrees F. (37 degrees C.), in practice a person is usually not considered to have a significant fever until the temperature is above 100.4 degrees F (38 degrees C.).

Flu: Short for influenza. The flu is caused by viruses that infect the respiratory tract which are divided into three types, designated A, B, and C. Most people who get the flu recover completely in 1 to 2 weeks, but some people develop serious and potentially life-threatening medical complications, such as pneumonia. Much of the illness and death caused by influenza can be prevented by annual influenza vaccination.
Gastroenteritis: Inflammation of the stomach and the intestines. Can cause nausea and vomiting and/or diarrhea. Gastroenteritis has numerous causes: including infectious organisms (viruses, bacteria, etc.), food poisoning, and stress.
Giardia: A genus of protozoa that infect the gastrointestinal tract of some animals, including humans. Giardia have a large sucking disk which permits them to adhere to the intestinal lining. The species that infects humans (and causes diarrhea ) is Giardia lamblia .

Headache : A pain in the head with the pain being above the eyes or the ears, behind the head (occipital), or in the back of the upper neck. Headache, like chest pain or back ache, has many causes.

Immune: Protected against infection. The Latin immunis means free, exempt.
Infection: The growth of a parasitic organism within the body. (A parasitic organism is one that lives on or in another organism and draws its nourishment therefrom.) A person with an infection has another organism (a "germ") growing within him, drawing its nourishment from the person.

Inflammation: A basic way in which the body reacts to infection , irritation or other injury, the key feature being redness, warmth, swelling and pain . Inflammation is now recognized as a type of nonspecific immune response .

Influenza: The flu is caused by viruses that infect the respiratory tract which are divided into three types, designated A, B, and C. Most people who get the flu recover completely in 1 to 2 weeks, but some people develop serious and potentially life-threatening medical complications, such as pneumonia. Much of the illness and death caused by influenza can be prevented by annual influenza vaccination.
Laboratory: A place for doing tests and research procedures and preparing chemicals, etc. Although "laboratory" looks very like the Latin "laboratorium" (a place to labor, a work place), the word "laboratory" came from the Latin "elaborare" (to work out, as a problem, and with great pains), as evidenced by the Old English spelling "elaboratory" designating "a place where learned effort was applied to the solution of scientific problems."

Norovirus: A group of viruses that are a common cause of food poisoning and acute gastroenteritis ("stomach flu") that can strike quickly with force and make a person feel very sick but which typically resolves within 2-3 days. The characteristic symptoms are nausea, vomiting, diarrhea , and abdominal cramping. The diarrhea is not bloody. Fever, if present, is low-grade. Dehydration is the main complication, especially in infants and the elderly, and may need medical attention.
See the entire definition of Norovirus
Norwalk virus: A family of small round viruses that are an important cause of viral gastroenteritis (viral inflammation of the stomach and intestines). Norwalk disease is a significant contributor to illness in the US. Only the common cold is reported more frequently as a cause of disease. About a third of all cases of viral gastroenteritis after infancy are due to Norwalk viruses.

Nursing: 1) Profession concerned with the provision of services essential to the maintenance and restoration of health by attending the needs of sick persons. 2) Feeding a infant at the breast.
Prescription: A physician's order for the preparation and administration of a drug or device for a patient. A prescription has several parts. They include the superscription or heading with the symbol "R" or "Rx", which stands for the word recipe (meaning, in Latin, to take); the inscription, which contains the names and quantities of the ingredients; the subscription or directions for compounding the drug; and the signature which is often preceded by the sign "s" standing for signa (Latin for mark), giving the directions to be marked on the container.
Rehydration: The process of restoring lost water to the body tissues and fluids. Prompt rehydration is imperative whenever dehydration occurs, from diarrhea, exposure, lack of drinking water, or medication use. Rehydration can be by the oral route or by the intravenous administration of fluids.
Rotavirus (RV): A leading cause of severe winter diarrhea in young children, RV each year causes an estimated 500,000 doctor visits and 50,000 hospital admissions in the United States. Almost everyone catches RV before entering school but, with rehydration (and good nutrition), nearly all recover fully. However, in poor countries it is estimated that there are at least 600,000 deaths of children under 5 years from RV diarrhea and dehydration .

Salmonella: A group of bacteria that cause typhoid fever and a number of other illnesses, including food poisoning , gastroenteritis and enteric fever from contaminated food products.

Stomach: 1. The sac-shaped digestive organ that is located in the upper abdomen, under the ribs. The upper part of the stomach connects to the esophagus, and the lower part leads into the small intestine.

Stomach flu: So-called "stomach flu" actually has nothing to do with the influenza (flu) virus. This term is sometimes used to describe gastrointestinal illnesses caused by other microorganisms.
Stool: The solid matter discharged in a bowel movement.
Viral: Of or pertaining to a virus. For example, "My daughter has a viral rash ."

Virus: A microorganism smaller than a bacteria, which cannot grow or reproduce apart from a living cell. A virus invades living cells and uses their chemical machinery to keep itself alive and to replicate itself. It may reproduce with fidelity or with errors (mutations)-this ability to mutate is responsible for the ability of some viruses to change slightly in each infected person, making treatment more difficult.
See the entire definition of Virus
Viruses: Small living particles that can infect cells and change how the cells function. Infection with a virus can cause a person to develop symptoms. The disease and symptoms that are caused depend on the type of virus and the type of cells that are infected.
