When a person becomes infected with norovirus, the virus is replicated within the small intestine. After approximately one to two days, norovirus infection symptoms can appear.

The principal symptom is acute gastroenteritis that develops between 12 and 48 hours after exposure, and lasts for 24—72 hours. General lethargy, weakness, muscle aches, headache, cough, and low-grade fever may occur.

Severe illness is rare; although people are frequently treated at the emergency ward, they are rarely admitted to the hospital. The number of deaths from norovirus in the United States is estimated to be around — [52] each year, with most of these occurring in the very young, the elderly, and persons with weakened immune systems.

Symptoms may become life-threatening in these groups if dehydration or electrolyte imbalance is ignored or not treated.

Specific diagnosis of norovirus is routinely made by polymerase chain reaction PCR assays or quantitative PCR assays, which give results within a few hours.

These assays are very sensitive and can detect as few as 10 virus particles. Tests such as ELISA that use antibodies against a mixture of norovirus strains are available commercially, but lack specificity and sensitivity.

Due to a lack of specific therapy, the need for expensive stool diagnostics is being questioned by experts if gastroenteritis by noroviruses has already been detected in the environment.

After infection , immunity to the same strain of the virus — the genotype — protects against reinfection for between 6 months to 2 years.

In Canada , norovirus is a notifiable disease. Hand washing with soap and water is an effective method for reducing the transmission of norovirus pathogens.

In health-care environments, the prevention of nosocomial infections involves routine and terminal cleaning.

Nonflammable alcohol vapor in CO 2 systems is used in health care environments where medical electronics would be adversely affected by aerosolized chlorine or other caustic compounds.

In , the CDC published a clinical practice guideline addressing strategies for the prevention and control of norovirus gastroenteritis outbreaks in health-care settings.

The guideline also identifies eight high-priority recommendations and suggests several areas in need of future research.

LigoCyte announced in that it was working on a vaccine and had started phase 1 trials. Since there is no RNA in this particle, it is incapable of reproducing and cannot cause an infection.

The norovirus can survive for long periods outside a human host depending on the surface and temperature conditions: it can survive for weeks on hard and soft surfaces, [71] and it can survive for months, maybe even years in contaminated still water.

Routine protocols to detect norovirus in clams and oysters by reverse transcription polymerase chain reaction are being employed by governmental laboratories such as the Food and Drug Administration FDA in the US.

There is no specific medicine to treat people with norovirus illness. Norovirus infection cannot be treated with antibiotics because it is not a bacterial infection.

Treatments aim to avoid complications by measures such as the management of dehydration caused by fluid loss in vomiting and diarrhea, [5] and to mitigate symptoms using antiemetics and antidiarrheals.

Age and emergence of new norovirus strains do not appear to affect the proportion of gastroenteritis attributable to norovirus. Norovirus is a common cause of epidemics of gastroenteritis on cruise ships.

Epidemiological studies have shown that individuals with different ABO H histo- blood group phenotypes are infected with NoV strains in a genotype-specific manner.

The ABH-antigen produced is thought to act as a receptor for human norovirus: A non-functional fucosyltransferase FUT2 provides high protection from the most common norovirus strain, GII.

Homozygous carriers of any nonsense mutation in the FUT2 gene are called non-secretors , as no ABH-antigen is produced.

The norovirus was originally named the "Norwalk agent" after Norwalk, Ohio , in the United States, where an outbreak of acute gastroenteritis occurred among children at Bronson Elementary School in November although an outbreak had already been discovered in in Roskilde, Denmark, where it is commonly known as "Roskilde syge" or "Roskilde illness".

In , electron microscopy on stored human stool samples identified a virus, which was given the name "Norwalk virus".

Numerous outbreaks with similar symptoms have been reported since. The cloning and sequencing of the Norwalk virus genome showed that these viruses have a genomic organization consistent with viruses belonging to the family Caliciviridae.

This was also a public response by ICTV to the request from an individual in Japan to rename the Norovirus genus because of the possibility of negative associations for people in Japan and elsewhere who have the family name "Noro".

In addition to "Norwalk agent" and "Norwalk virus", the virus has also been called "Norwalk-like virus", "small, round-structured viruses" SRSVs , Spencer flu and "Snow Mountain virus".
