What is another name for norovirus? What disease does norovirus cause?

Norovirus, also known as the winter vomiting bug in the UK, is a highly contagious virus that is the most common cause of gastroenteritis. Gastroenteritis is an inflammation of the stomach and intestines, which leads to symptoms such as stomach pain, nausea, diarrhea, and vomiting.

Norovirus is named after the original strain “Norwalk virus,” which caused an outbreak of gastroenteritis in a school in Norwalk, Ohio, in 1968. Since then, many similar viruses have been identified, all of which belong to the Norovirus genus. These viruses are classified into different genogroups and genotypes. For example, the strains that most commonly infect humans belong to the genogroups GI and GII.

The disease caused by norovirus, often referred to as “norovirus illness,” is characterized by acute onset of symptoms, which usually last for one to three days. The virus is transmitted through the fecal-oral route, which means that you can get infected if you consume food or water that has been contaminated with feces from an infected person, or if you touch contaminated surfaces or objects and then touch your mouth.

Despite its unpleasant symptoms, norovirus illness is usually not serious. Most people recover fully without treatment within a few days. However, it can be dangerous for people who have a weakened immune system, the very young, or the elderly, as they are more susceptible to severe dehydration. Therefore, if you or someone you care for has norovirus illness, it’s important to drink plenty of fluids to prevent dehydration. If symptoms persist or are severe, seek medical attention.
