What is the disease?

Noroviruses are the most common cause of viral gastroenteritis. It can also be called the stomach flu, but it is not related the flu. Their high incidence and importance in health care facilities result in a great impact on public health. A norovirus is a small virus that contains RNA and is surrounded by a protein coating.There are over 25 strains of the virus.


The symptoms are similar to those of a common viral infection. So therefore they have to do specific tests to determine if it is a norovious.

Tests used:

-Using RNA in the virus they can use polymerase chain reaction(most common)

-Enzyme-based immunoassays in stool samples

- This is the newest type of test and it is used when you are trying to detect a norovirus that contaminated a group of people(used a shared food source or location).

** Your body makes antibodies that work against the norovirus, they can be identified with immunoassay testing of blood samples



- Fever(occurs is over 1/3 of infected people

-Cramping abdominal or stomach pain



-Muscle Ache

- Thirsty( because they loose fluids through diarrhea, vomiting)

- Children might not be thirsty but may appear listless or lethargic from dehydration

** Usually the cases of norovirus are mild but in severe cases, there might be a need for hospitalization because of dehydration.

Freuency and Target Audience

Like mentioned above it is the most common frequent causes of acute nonbacterial gastroenteritis. Sometimes it will occur is an outbreak, or just randomly in people. It can happen in any public places, like a school, job.. etc. Approximately 20% of adults who go to the doctor for a acute infectious diarrhea have norovirus. It can happen to anyone, kids, adults, and elderly.

How long will it last?

Norovirus can have a prolonged infection period that starts before the patient is even sick. there is a short lag or incubation period ( up to two days) between the time that people get the virus and the time they get symptoms.All people are contagious while they are having symptoms. Even when you are free of all symptoms you are most likely still shedding the virus in your stool, and during this time period you are still infectious to others.
