What is Norovirus?

The norovirus causes gastroenteritis, which is a severe stomach illness. It is sometimes called the “stomach flu”, although it is not caused by influenza. The norovirus is very contagious and can easily spread from person to person.

Norovirus is found in the stools and vomit of infected individuals. Similarly, it can be found on contaminated surfaces such as door handles or countertops. 

Norovirus can be spread by touching contaminated surfaces and then touching their mouths or eating contaminated foods.

Norovirus is characterized by the following symptoms:

  • Vomiting
  • Diarrhea
  • Stomach pain
  • Nausea

Norovirus symptoms in adults include:

  • Fever
  • Headache
  • Pain in the body

There is an inflammation of the stomach or intestines caused by norovirus. The condition is known as acute gastroenteritis.

Norovirus symptoms usually appear between 12 and 48 hours after exposure. It usually takes one to three days for a person with norovirus illness to recover.

If you have norovirus illness, you may feel extremely ill and have diarrhea or vomiting several times a day. It can cause dehydration, especially in children, the elderly, and sick individuals.
