The Norovirus: A Study in Puked Perfection


What is this fearsome bug, you may be asking, and why isn’t it the subject of a Hollywood horror movie?

Noroviruses are one of virology’s great open secrets. In a recent issue of The Journal of Infectious Diseases, Aron Hall of the Centers for Disease Control declared, “Noroviruses are perhaps the perfect human pathogen.”

Here’s what inspires awe in scientists like Hall.

Each norovirus carries just nine protein-coding genes (you have about 20,000). Even with that skimpy genetic toolkit, noroviruses can break the locks on our cells, slip in, and hack our own DNA to make new noroviruses. The details of this invasion are sketchy, alas, because scientists haven’t…

8 Symptoms of Norovirus

Amongst the most common of viral gastroenteritis in human beings...

CDC

Norovirus is a very contagious virus that can infect anyone. You can get it from an infected person, contaminated food or water, or by touching contaminated surfaces. The virus causes your stomach or intestines or both to get inflamed. This leads you to have stomach pain, nausea, and diarrhea and to throw up.

MayoClinic

Typically, people with norovirus infection develop diarrhea and abdominal pain and begin to vomit within 24 to 48 hours of exposure. Norovirus symptoms may last a few days, but most people recover completely without treatment. However, in some people – especially infants, older adults and people with underlying disease – vomiting and diarrhea can be severely dehydrating and require medical attention.

Patient

Noroviruses are a group of viruses that can cause gastroenteritis. Gastroenteritis is an infection of the gut (intestines) which usually causes vomiting and diarrhoea. Norovirus is the most common virus causing gastroenteritis in adults in the UK. In most cases the infection clears within a few days, but sometimes takes longer. The main risk is dehydration.
