loose or watery diarrhoea
a minor fever
Typically, signs and symptoms appear 12 to 48 hours after your first norovirus encounter and last 1 to 3 days.
After healing, you may continue to pass the virus in your for a few weeks.

When infected with norovirus, some persons may not exhibit any symptoms at all.
They can still spread the infection to others because they are contagious.
The most typical reason for gastroenteritis is norovirus, sometimes known as the winter vomiting disease.
 Non-diarrhoea, vomiting, and stomach pain are symptoms of infection.
 Other symptoms include fever or headaches.
 Symptoms often appear 12 to 48 hours after exposure, and recovery normally takes place between one and three days.
Complications are uncommon, but may include dehydration, especially in the young, the old, and those with other health problems.
The virus is usually spread by the route.
 This may be through contaminated food or water or person-to-person contact.
 It may also spread via contaminated surfaces or through air from the vomit of an infected person.
 Risk factors include unsanitary food preparation and sharing close quarters.  Diagnosis is generally based on symptoms.

Symptoms and signs
An infection with the norovirus is characterised by nausea, vomiting, diarrhoea that is watery, abdominal pain, and, occasionally, loss of taste.
The typical incubation period for gastrointestinal symptoms is 12 to 48 hours after norovirus exposure. It is possible to experience general weakness, muscle aches, headaches, and low-grade fevers.Severe illness is uncommon and the disease typically has a self-limiting course.Even though the norovirus can be unpleasant, it is usually not harmful, and the majority of people who get it recover completely in two to three days.
Immunocompromised individuals, such as those with common variable immunodeficiency or those whose immune systems have been reduced following donation, are more susceptible to developing a long-lasting infection from norovirus.
These infections may or may not present with symptoms.
Indications and Symptoms
The symptoms of a norovirus infection include nausea, vomiting, watery diarrhea, abdominal pain, and, rarely, taste loss.
After exposure to norovirus, the average incubation period for gastrointestinal symptoms is 12 to 48 hours.
There’s a chance you’ll feel generally weak, and have headaches, aches in your muscles, and a low-grade fever.
Rare cases of severe illness occur, and the condition normally progresses in a self-limiting manner.
The majority of those who contract the norovirus recover well within two to three days, despite the fact that it can occasionally be unpleasant.
Norovirus infections can linger for a long time in people with impaired immune systems, such as those with common variable immunodeficiency or those whose immune systems have been compromised as a result of the donation.
The cytoplasm is where viral replication occurs.
Attachment to host receptors, which triggers endocytosis, allows entry into the host cell.
The process of replication is a transcription by positive-stranded RNA viruses.
Leaky scanning and RNA termination-reinitiation are the methods used in translation.
The natural hosts are people and other mammals.
