What Are Some of the Symptoms of Norovirus?

Symptoms of norovirus infection include nausea, vomiting, abdominal pain, cramps and loose diarrhea, according to Mayo Clinic. Other symptoms include general malaise, fever and muscle pain.

Norovirus symptoms usually begin 24 to 48 hours after the patient is exposed to the virus, notes Mayo Clinic. Symptoms often last from one to three days, and the body continues to expel the virus for up to three days following recovery from primary symptoms.

Norovirus causes stomach and intestine inflammation, or gastroenteritis, notes WebMD. The virus is contracted by ingesting contaminated food or drinks, such as raw or undercooked oysters, fruits and vegetables. It is also transmitted by touching infected objects or surfaces and then touching the nose, mouth or eyes.
