General Information About Norovirus
Disease Details and Frequently Asked Questions
It is a highly contagious type of virus that causes inflammation of the mucosal lining of the stomach and intestines.
It spreads rapidly by touching surfaces contaminated with the feces or vomit of infected individuals, bringing contaminated hands to the mouth, or consuming virus-contaminated food (especially seafood and unwashed vegetables).
Symptoms include projectile severe vomiting, watery diarrhea, stomach cramps, mild fever, and muscle aches that begin suddenly 12 to 48 hours after the virus enters the body.
The virus itself does not cause permanent damage to organs; however, the severe vomiting and diarrhea it induces lead to sudden and potentially life-threatening fluid and mineral loss (dehydration) in the body. This condition is particularly dangerous for the elderly and infants.
Clinical symptoms and outbreak history are generally sufficient for diagnosis. Definitive laboratory diagnosis is established by detecting the genetic material of the virus through a PCR test on a collected stool (feces) sample.
Because it is a viral illness, antibiotics are ineffective. There is no specific antiviral medication. The primary treatment relies on replacing the fluids and electrolytes lost by the patient orally (ORS solutions) or intravenously via serum administration.
